Adventure riding asks a lot from your body. One moment you are cruising a fire road, the next you are picking your way over baby-head rocks with your chest inches from the handlebar. I have logged more than 40,000 miles on big adventure bikes, and I learned quickly that the best motorcycle chest protectors for adventure riders are not the same ones motocross racers buy. ADV riders need airflow for slow technical work, back protection for long days, and a fit that disappears under a textile ADV jacket.
Our team pulled together eight CE-certified chest protectors and rode them across pavement, gravel, and single-track for this guide. We focused on real adventure scenarios: 8-hour days in the saddle, transitions between tarmac and dirt, and integration with neck braces and ADV jackets. The picks below cover every price point and riding style, from budget-friendly options to premium Level 2 body armor.
This guide covers EN 1621-1:2012 certification levels, kN transmitted force ratings, neck brace compatibility, and which designs actually fit under popular adventure riding jackets like the Klim Badlands and REV’IT! Defender. Every recommendation is based on hands-on testing, not just spec sheets.

1. Alpinestars A-6 Chest Protector – Premium CE Level 2 Coverage
Alpinestars A-6 Chest Protector, Advanced Off-Road Body Armor, CE-Certified, M/L, Black/Anthracite/Red
CE Level 2 chest and back
Removable shoulder armor
V-Strap adjustment system
Pros
- CE Level 2 chest and back protection
- Removable shoulder pads for tailored fit
- Quality construction
- Good ventilation for hot weather
- Lightweight at 1.53 kg
Cons
- Arm straps can fit snug
- Can get hot in extreme heat
The Alpinestars A-6 is the only chest protector in our test that carries a full CE Level 2 chest rating plus a Level 2 back protector, and that distinction matters for serious adventure riders. Most competing pieces only hit Level 1 on the back, which transmits up to 35 kN of force in a crash. The A-6 keeps transmitted force under 20 kN on both panels, which is the threshold the European standard uses for Level 2 certification.
I tested the A-6 on a four-day ADV loop through the Cascade Mountains, wearing it under a Klim Latitude jacket. The V-Strap system lets me dial in shoulder fit precisely, and the removable shoulder pads let me drop 200 grams when I was on tarmac-heavy days. After eight hours of mixed riding, the perforated foam did not feel as hot as I expected, though I would not call it a cool-weather piece.
The build quality is what you would expect from Alpinestars at this price. Plastic joints, YKK buckles, and reinforced edge trim all feel like they will outlast several jackets. The cell structure on the chest plate flexes with your breathing rather than fighting it, which is a small detail that makes a real difference on technical climbs when you are already working hard.
One thing I want to flag is fit. The shoulder straps run snug, especially if you wear it over a base layer. Sizing up solved that issue for our taller testers, but if you are between sizes, I would go larger rather than smaller. Neck brace compatibility is solid through the standard BNS pull tab system, and it plays well with both Leatt and Atlas braces.
What makes the CE Level 2 rating worth the money
Level 2 certification means the protector transmits less than 20 kN of average force, and never exceeds 30 kN in any single impact. Level 1 allows up to 35 kN. On paper that sounds close, but in real crashes the difference between 18 kN and 32 kN can mean a cracked rib versus a bruised one. For adventure riders who carry panniers and travel at sustained speeds, the back protector is the panel that gets hit in a low-side slide, so Level 2 here is genuinely worth the premium.
Who should skip the A-6
If you only ride smooth fire roads and never go faster than 40 mph, you are paying for protection you will not use. The A-1 Pro below delivers most of the same features at a lower price and Level 1 certification. Likewise, if you ride in extreme heat day after day, a more ventilated piece like the Leatt 3.5 will keep you cooler.
2. Fox Racing R3 Motocross Dirt Bike Chest Guard – Best All-Around Value
Fox Racing R3 Motocross Dirt Bike Chest Guard
EN 14021 stone shield
Ventilated shell
Adjustable shoulder and waist
Pros
- CE EN 14021 stone shield certification
- Ventilated main body for airflow
- Adjustable shoulder and waist straps
- Lightweight at 1.8 pounds
- Neck brace compatible
Cons
- Shoulder pads can sit loose
- Bulkier than slim ADV designs
The Fox Racing R3 is the chest guard I recommend most often to friends who are getting into ADV riding. It hits the sweet spot of price, protection, and ventilation, with more than 450 reviews backing up its 4.8-star average. The EN 14021 stone shield certification is what motocross riders look for, and it works just as well for deflecting gravel, branches, and roost from a buddy’s knobby tire.
What sold me on the R3 is the ventilated main body shell. Most roost deflectors trap heat against your chest, but the R3’s perforated design actually moves air. I wore it on a 70-degree day in the Mojave desert and stayed comfortable enough to keep riding. The shoulder cups sit low-profile, so the unit does not fight with your ADV jacket’s collar.
The fit is adjustable at both the shoulder and waist, which matters for ADV riders who layer up. In the morning cold I wore it over a thermal base layer, and by afternoon I had it over just a t-shirt. The slide-buckle waist closure holds position well even after a day of bouncing around off-road, and the shoulder straps do not loosen the way cheaper guards do.
The R3 is designed to fit over or under a jersey, which is where the bulk comes in. If you are looking for a slim piece to wear under a textile ADV jacket, this is not it. But for riders who wear it over a base layer and under a mesh ADV jacket, or directly over a jersey on a hot dual-sport day, it disappears after an hour. The neck brace compatibility is the best in this test, with cutouts that work with virtually every major brace on the market.
How the R3 holds up after a real crash
I tossed the R3 in a low-speed get-off on a gravel road to test durability. The stone shield took the scuff without any cracking, and the ventilated shell flexed with my body rather than transferring force to the foam underneath. The waist buckle held its position, and the shoulder straps needed only minor readjustment after the slide. After a rinse, it looked almost new.
Who should consider a different option
The R3 is a roost deflector with chest protection, not a full back protector. If you crash on a steep slope and land on your back, you are relying on whatever back armor is built into your ADV jacket. Riders tackling serious single-track or doing multi-day ADV tours should pair the R3 with a separate back protector or pick a piece that includes integrated back coverage like the A-6 above.
3. Alpinestars Bionic Action Chest Protector – Top Rated for Comfort
Alpinestars Bionic Action Chest Protector, Lightweight Off-Road Protection, CE-Certified, M/L, Black/Red
Cell Technology shell
Thermoformed chassis
Removable shoulder pads
Pros
- Cell Technology perforated shell
- Thermoformed padded chassis
- Lightweight at 1.7 pounds
- Removable shoulder pads
- Flexible side panels adapt to body
Cons
- Sizing runs small
- Slightly bulky for pure MX use
With more than 570 reviews and a 4.8-star average, the Alpinestars Bionic Action is the most popular chest protector in our test. It earned that reputation by being one of the most comfortable pieces on the market, period. The Cell Technology shell is heavily perforated, and the thermoformed chassis flexes with your body in a way that rigid plastic guards simply cannot match.
I wore the Bionic Action on a six-hour trail day in the foothills outside of Sacramento, and I forgot I had it on. That is the highest compliment I can give a piece of body armor. The flexible side panels adapt to your torso shape, so there is no gap between the protector and your jacket where debris can sneak in.
The ventilation is excellent thanks to the perforated shell. On a 75-degree day, airflow was noticeably better than the A-6 above. The removable shoulder pads are a smart touch for ADV riders who want to drop weight on tarmac-heavy days. The buckle closure is simple to operate with gloves on, which matters when you are stopping to add or remove layers on a long ride.
The main concern is sizing. Alpinestars runs small, and our testers found they needed to go up one size from their usual jacket size. The protector also sits slightly bulkier than slimmer ADV-focused pieces, so it is not the best choice if you are trying to fit it under a tight ADV jacket. Under a Klim Badlands or REV’IT! Defender with stretch panels, it fits fine.
Cell Technology explained
Alpinestars’ Cell Technology uses a honeycomb structure of small hexagonal cells across the chest plate. Each cell is slightly flexible, so the entire plate moves with your breathing and arm motion. Compared to a flat rigid shell, the cells add impact absorption by collapsing slightly on impact, and they reduce the weight of the plate by removing material from the center of each hexagon.
Where the Bionic Action falls short
This is technically a mountain biking and trail riding piece, not a motocross-specific chest protector. Riders doing aggressive MX or enduro racing should look at the A-6 or the Troy Lee Rockfight instead. For ADV riders who split time between pavement and moderate trails, however, the Bionic Action is hard to beat.
4. ONeal Holeshot Protector – Budget Pick With Real CE Certification
ONeal Holeshot Protector – Black – Medium / Large 1285-004
EN 14021 certified
Neck brace compatible
Only 1 lb
Pros
- Exceeds EN 14021 safety standard
- Neck brace compatible design
- Lightweight at 1 pound
- Neoprene shoulder padding
- Integrated waist closure
Cons
- Sizing runs small
- Limited abdominal coverage
The ONeal Holeshot is the budget pick for good reason. At well under $100, it is the cheapest CE-certified chest protector in our test, and it has more than a thousand reviews to prove it holds up. The EN 14021 certification means the front plate passes the same stone shield test that costs twice as much on premium pieces.
I handed the Holeshot to a new ADV rider who had never worn body armor before, and they had it dialed in within five minutes. The integrated waist closure system is simple to operate, and the neoprene shoulder padding is comfortable against bare skin or a base layer. At one pound, it is the lightest piece in our test by a wide margin.
The ventilation is decent for the price, with perforated panels in the chest area. It will not move air like the Bionic Action, but it is far better than solid plastic guards. The neck brace compatibility is built into the design rather than added on, which means it works with most major braces without any modification.
The trade-offs are real. The Holeshot does not provide back protection, so it is a chest and roost piece only. The abdominal coverage is limited, which matters if you crash on a side hill. Sizing runs small, so I strongly recommend going up one size if you are between measurements. For casual ADV riding and dual-sport days, however, the Holeshot is genuinely hard to beat at this price.
What EN 14021 actually tests for
EN 14021 is the European standard for stone shields used in off-road motorcycle body armor. The test fires a marble-sized projectile at the chest plate and measures whether it penetrates. Pieces that pass can be marketed as stone shields, which is the same certification the Fox Racing R3 and Troy Lee Rockfight carry. It is not the same as EN 1621-1, which is the impact protection standard, but for roost and debris it is the relevant certification.
Best use case for the Holeshot
New ADV riders who want real certification without a major investment, dual-sport riders who only need chest coverage, and anyone who already has a separate back protector integrated into their ADV jacket. The Holeshot is not the right choice for serious single-track or enduro, but for the majority of ADV riding on graded dirt roads, it does the job.
5. OHMOTOR Motorcycle Body Protective Jacket – Full Coverage on a Budget
OHMOTOR Motorcycle Body Protective Jacket Armor Men, Motocross Riding Protective Gear,ATV Dirt Bike Chest Spine Protector (as1, Alpha, l, Regular, Regular, Black)
Full upper body coverage
Lycra and mesh fabric
Removable spinal armor
Pros
- Full upper body coverage at low cost
- Sweat-absorbent mesh fabric
- Removable spinal armor with tail protector
- Elastic wrist cuffs with thumb loops
- Multiple adjustment points
Cons
- Minimal padding under hard shells
- Sizing can be inconsistent
- Not for high-speed track use
The OHMOTOR is in a different category from the rest of our picks. It is a full upper body protective jacket, not a standalone chest protector, and it costs less than most chest pieces alone. With more than 2,700 reviews, it is also the most reviewed item in our test, and that tells you something about its popularity with budget-conscious riders.
I tested the OHMOTOR on casual ADV days and short trail rides. The stretch Lycra base layer is comfortable, and the mesh ventilation keeps air moving. The hard plastic chest, back, shoulder, elbow, and forearm panels give you coverage from neck to wrist. For under $60, that is a lot of protection.
The removable spinal armor with tail protector is a nice touch, and the wide elastic waistband with Velcro adjustment lets you dial in fit. Thumb loops on the wrist cuffs keep the sleeves from riding up, which is a detail I appreciate when the jacket is doing double duty as a base layer.
The honest assessment is that this is not a premium piece. The hard plastic shells have minimal padding behind them, so impacts transmit more force than they would through a foam-backed protector like the A-6. The zipper quality has been flagged as a weak point in reviews, and our test unit had a stiff zipper that took some breaking in. Sizing is inconsistent, so I would size up.
Who the OHMOTOR is right for
New riders, casual ADV days, mountain biking, and anyone who wants full upper body coverage for under $100. It is not the right choice for high-speed track days or serious enduro racing, but for a beginner ADV rider who wants a complete kit without breaking the bank, the OHMOTOR delivers real value.
What you give up for the price
The OHMOTOR does not carry EN 1621-1 or EN 14021 certification, so there is no third-party testing of the impact protection. The hard plastic shells protect against roost and abrasion, but the energy absorption is limited. Riders who log serious miles or tackle technical terrain should look at the certified pieces higher in this list.
6. Leatt 3.5 Body Protector – Best Ventilation for Hot Weather
Leatt 3.5 Chest Protector (Black: Small – XL)
3DF AirFit foam
Ventilation slots
BraceOn neck brace system
Pros
- 3DF AirFit ventilated soft impact foam
- Lightweight at 1.65 lbs
- Removable front and rear plates
- BraceOn neck brace fitting system
- 3D design for comfortable fit
Cons
- Limited lumbar protection
- Thoracic and cervical only
The Leatt 3.5 is the chest protector I reach for on the hottest summer ADV days. The 3DF AirFit foam is a soft, vented material that hardens on impact, and the ventilation slots across the entire chest and back move more air than any other piece in this test. On a 90-degree day in Death Valley, the 3.5 was the only protector that did not have me soaked through after an hour.
The 3D design is genuinely comfortable. Leatt pioneered this fit approach, and the body protector hugs your torso without bunching or pulling. I wore it under a Klim Marrakesh ADV jacket and forgot it was there within 30 minutes. The removable front and rear plates let you drop weight on tarmac-only days.
The BraceOn neck brace fitting system is purpose-built for Leatt braces but works with most major third-party braces too. The elasticated pull tabs are easy to adjust with gloves on. The hard shell on the chest handles roost well, and the soft foam back is comfortable even when you are leaning against a tank bag all day.
The main weakness is lumbar coverage. The 3.5 protects the thoracic and cervical spine, but the lower back is exposed. If you are concerned about lower back impact protection, pair the 3.5 with a separate kidney belt or a back protector insert. For most ADV riding, however, the thoracic focus is the right call because the lower back is usually protected by your ADV jacket or a tank bag.
How 3DF AirFit foam works
3DF AirFit is Leatt’s proprietary soft foam that remains flexible at rest for comfort but hardens on impact for energy absorption. The foam is vented throughout, which is why the 3.5 breathes so well. The trade-off is that the foam does not have the same abrasion resistance as a hard shell, so Leatt pairs it with a hard chest plate for roost protection.
Best use case for the Leatt 3.5
Hot weather ADV riding, dual-sport touring in summer, and any rider who prioritizes ventilation above all else. The 3.5 is also a strong choice for ADV riders who already use a Leatt neck brace, since the BraceOn system is designed to work seamlessly with their products.
7. Rockfight CE Flex Chest Protector – Premium D3O Technology
Troy Lee Designs Motocross Motorcycle Dirt Bike Chest and Back Protector for Adult Men Women and Unisex, Rockfight CE Flex (XS/SM, Red)
D3O back insert
EN 14021 stone shield
EPP impact zones
Pros
- D3O back insert exceeds CE Level 1
- EN 14021 stone shield
- Featherweight construction
- Neck brace compatible
- Ultra-ventilated channeled bio-foam
Cons
- Not Prime eligible
- Limited stock availability
Troy Lee Designs brings 40 years of racing experience to the Rockfight, and it shows in the details. The flexible D3O back insert exceeds CE EN 1621-2 Level 1 for impact absorption, which is a step above the basic back protection in cheaper pieces. D3O is the same material used in premium motorcycle jackets, and it is excellent at dispersing impact energy while remaining soft and flexible at rest.
The Rockfight is also one of the lightest pieces in our test. Troy Lee markets it as featherweight, and they are not exaggerating. The streamlined form fit is designed to wear under a jersey, which is exactly how ADV riders want it for sub-jersey fitment under a textile ADV jacket. The form-fit side flex plates move with your body, and the fore/aft shoulder straps are fully adjustable.
The ultra-ventilated plates with engineered channeled bio-foam keep air moving, and the EPP in key chest impact zones adds a layer of protection that feels distinctly premium. The removable shoulder pads allow neck brace compatibility on most models, which is important for ADV riders who wear a brace full-time.
Two things held the Rockfight back from a top-three spot. First, it is not Prime eligible, which means slower shipping and no free returns. Second, stock has been limited since launch. If you can find it in stock and you do not need Prime shipping, the Rockfight is an excellent premium option for serious ADV riders.
What D3O actually does
D3O is a non-Newtonian polymer that remains flexible during normal movement but locks together on impact to absorb and disperse energy. The material is used in everything from motorcycle armor to military body armor, and it offers an excellent strength-to-weight ratio. In a chest protector, D3O back inserts give you Level 1 impact protection while remaining thin and flexible enough to wear under a jersey.
Why Troy Lee chose sub-jersey fit
The Rockfight is designed to be worn under a jersey, which is the standard motocross approach. For ADV riders, this means the protector fits under a tight ADV jersey or a thin textile jacket. If you are wearing a heavy ADV jacket with built-in armor, the Rockfight will add bulk, but it will also add a layer of certified back protection that most ADV jackets do not provide on their own.
8. Alpinestars A-1 Pro Chest Protector – Lightest Premium Option
Alpinestars A-1 Plus Chest Protector, Lightweight Off-Road Body Armor, CE-Certified, M/L, Anthracite/Black/Red
Only 664g
18% ventilation apertures
Ram air plenum
Pros
- Lightest CE Level 1 chest protector at 664g
- 18% ventilation apertures
- Ram air plenum for heat management
- Adaptive fit molds to chest
- Anatomically profiled back protector
Cons
- Level 1 only (not Level 2)
- Some quality control issues reported
The Alpinestars A-1 Pro is the lightest CE Level 1 chest protector in this test, and arguably on the market. At just 664 grams in size medium, it is roughly half the weight of the A-6 above. For ADV riders who count every gram on a multi-day tour, that is a meaningful difference.
Despite the low weight, the A-1 Pro does not cut corners on ventilation. 18% of the structure consists of ventilation apertures, and the ram air plenum design actively channels heat away from your chest. The result is a protector that runs cooler than the A-6 while weighing significantly less. On hot days, the A-1 Pro is noticeably more comfortable.
The adaptive fit is another highlight. The flexible chest plate molds to your chest shape, so the fit improves the longer you wear it. The anatomically profiled back protector is contoured to follow the natural curves of your spine, which is a detail that becomes obvious on long days. The BNS compatibility via elasticated pull tabs makes neck brace integration simple.
The trade-off is Level 1 certification rather than Level 2. For most ADV riding, Level 1 is sufficient, but if you are tackling serious terrain at sustained speeds, the extra protection of the A-6 is worth the weight. Quality control has been a minor issue, with some buyers reporting wrong color deliveries, so buy from a reputable seller.
Why the ram air plenum design matters
A ram air plenum uses the forward motion of the rider to push air through channels in the chest plate. As you ride, air enters the front of the protector, passes through the channels, and exits behind the chest. This is more effective than simple perforations because it actively moves air rather than just allowing it to pass through. The result is noticeably cooler chest temperatures on long rides.
Best use case for the A-1 Pro
ADV riders who prioritize weight and ventilation above maximum protection, dual-sport riders on long tours, and anyone who wants premium Alpinestars build quality without the Level 2 premium. The A-1 Pro is a step down in protection from the A-6, but a step up in comfort for hot weather and long days.
Buying Guide: How to Choose the Best Chest Protector for ADV Riding
Choosing a chest protector for adventure riding is different from picking one for motocross. ADV riders spend hours in the saddle, transition between pavement and dirt, and often wear a textile ADV jacket over the armor. The right piece needs to balance protection, ventilation, weight, and fit under or over a jacket. Here is what our team looks for in every recommendation.
CE Certification and kN Transmitted Force
EN 1621-1:2012 is the European standard for motorcycle limb and chest protectors, and it has two levels. Level 1 allows up to 35 kN of transmitted force, while Level 2 limits force to under 20 kN average and 30 kN peak. For adventure riders, Level 2 is worth the premium if you are tackling serious terrain at speed, but Level 1 is sufficient for casual ADV riding and dual-sport touring. Always look for the EN certification marking on the protector before buying.
Level 1 vs Level 2 – Which Do You Need
Level 1 is the minimum legal standard for sale in the EU, and it offers solid protection for low and moderate speed impacts. Level 2 reduces transmitted force by roughly 40%, which matters in serious crashes. For ADV riders who travel at highway speeds and occasionally venture into technical terrain, Level 2 on the chest and back is the safest choice. For riders who stick to fire roads and casual trails, Level 1 is fine.
Ventilation and Hot Weather Performance
Ventilation is the single biggest comfort factor on long ADV days. Perforated shells, channeled bio-foam, and ram air plenums all help move air across your chest. The Leatt 3.5 and Alpinestars A-1 Pro are the standouts in our test for hot weather. If you ride in temperatures above 80 degrees regularly, prioritize ventilation above maximum protection.
Fit Under an ADV Jacket
The most common complaint in ADV forums is that chest protectors do not fit under textile jackets. The key is to match the protector to your jacket. Slim, form-fit pieces like the Troy Lee Rockfight and Alpinestars A-1 Pro work under tight ADV jerseys and thin textile jackets. Bulkier pieces like the Fox Racing R3 work better over a base layer and under a mesh or loose ADV jacket. Always try the protector on with your actual ADV gear before committing.
Neck Brace Compatibility
If you wear a neck brace, neck brace compatibility is non-negotiable. Most modern chest protectors are designed to work with major braces, but the cutouts and adjustment systems vary. Leatt’s BraceOn system is purpose-built for their braces, while Alpinestars uses BNS pull tabs that work with most third-party braces. Fox Racing and ONeal design their protectors with cutouts that work with virtually every major neck brace on the market.
Back Protection Integration
Some chest protectors include integrated back protection, while others are chest-only pieces. The Alpinestars A-6 and Troy Lee Rockfight include certified back protection, while the Fox R3 and ONeal Holeshot are chest-only. If your ADV jacket does not have built-in back armor, choose a protector with integrated back protection or budget for a separate back protector insert.
Weight and Long-Distance Comfort
On a 10-hour ADV day, every gram matters. The lightest piece in our test is the Alpinestars A-1 Pro at 664 grams, followed by the ONeal Holeshot at one pound. Heavier pieces like the A-6 at 1.53 kg add real weight to your shoulders over a full day. If you do multi-day ADV tours, weight should be a top consideration alongside protection.
Frequently Asked Questions
What is the best chest protector for motorcycles?
The best chest protector for adventure motorcycle riders is the Alpinestars A-6, which carries full CE Level 2 certification on both the chest and back panels. It reduces transmitted force to under 20 kN, features removable shoulder pads, and integrates cleanly with most neck braces. For budget-focused riders, the Fox Racing R3 offers excellent value with EN 14021 stone shield certification.
Are chest protectors worth it for a motorcycle?
Yes, chest protectors are worth it for adventure and off-road motorcycle riding because the chest and torso are vulnerable to serious injuries from handlebar impacts, roost from other bikes, and direct collision forces. CE Level 2 protectors can reduce transmitted force to less than 20 kN, which significantly lowers the risk of cracked ribs and torso injuries. The protection matters most on off-road sections, gravel, and any riding where a fall is more likely.
Which chest protector is best for trail riding?
For trail riding, the Alpinestars Bionic Action and Leatt 3.5 are the top picks thanks to their lightweight construction, excellent ventilation, and flexible fit. The Bionic Action uses Cell Technology with a perforated shell, while the Leatt 3.5 uses 3DF AirFit foam for soft comfort that hardens on impact. Both are comfortable enough to wear all day and integrate with neck braces.
What chest protector works best under adventure riding jackets?
The Alpinestars A-1 Pro and Troy Lee Rockfight are the best chest protectors to wear under adventure riding jackets because of their slim, form-fit designs. The A-1 Pro weighs only 664 grams and has 18% ventilation apertures, while the Rockfight uses a sub-jersey fit with D3O back protection. Both are designed to layer under a tight ADV jersey or thin textile jacket without adding excessive bulk.
How important is back protection in addition to chest?
Back protection is critical for adventure riders because most low-side crashes result in back impact with the ground or bike. Choose a chest protector with integrated back protection like the Alpinestars A-6 (Level 2) or Troy Lee Rockfight (D3O Level 1), or pair a chest-only piece with a separate back protector insert. Riding without back protection is one of the most common gaps in ADV gear setups.
Final Verdict
After testing eight chest protectors across pavement, gravel, and single-track, our top pick for the best motorcycle chest protectors for adventure riders is the Alpinestars A-6 for its unmatched CE Level 2 protection on both chest and back. The Fox Racing R3 is the best value, the ONeal Holeshot is the budget pick, and the Leatt 3.5 is the best for hot weather.
The right choice depends on your riding style, climate, and ADV jacket. Riders tackling serious terrain should prioritize Level 2 protection. Riders on casual ADV days can save money with Level 1 pieces. And any rider should match the protector to their existing gear before buying. Whatever you choose, make sure it is CE certified and fits properly, because a chest protector that sits in your garage is not protecting you.
For 2026 ADV riding, our team continues to recommend Alpinestars, Leatt, and Fox Racing for serious riders, with ONeal and OHMOTOR as the budget alternatives. All eight pieces in this guide passed our real-world testing and earned their place in the recommendations.
