How To Choose The Best XXXL Motorcycle Helmet

Finding a helmet in 3XL is only half the battle; the other half is making sure it fits your head shape and riding style. Here are the three things that matter most when you are shopping in this size range.

Shell Size vs. Sticker Size

A helmet that simply pads out a medium shell to a 3XL label will feel heavy and bulbous. The best options use multiple shell sizes — a true 3XL shell that keeps the weight proportional and the center of gravity low, so your neck doesn’t tire on long rides.

Safety Certifications

DOT (Department of Transportation) is the baseline in the US, but ECE 22.06 is a tougher European standard that tests a wider range of impacts. If you ride aggressively or want the highest protection, look for helmets that carry both certifications or the newer ECE 22.06 rating.

Weight and Ventilation

Larger helmets mean more material, which adds weight. A heavy 3XL helmet (over 4.5 pounds) can strain your neck on a day-long ride. Good ventilation — adjustable top vents and exhaust ports — makes a big difference in comfort, especially in warmer weather, by preventing your head from overheating inside the shell.

In‑Depth Reviews

Best Overall

1. ScorpionEXO T520 Full Face Touring Motorcycle Helmet

Bluetooth ReadyDOT/ECE Certified

The touring veteran that balances all-day comfort with serious safety credentials.

The ScorpionEXO T520 is a crowd favorite for good reason. The thing everyone raves about is the fit — owners consistently praise how well it settles on the head, and the KwikWick ‘C’ moisture-wicking liner keeps you cool in the heat and warm when the temperature drops. The built-in EverClear fog-free shield and SpeedView drop-down sun visor mean you rarely have to stop to adjust for changing light. It is also Bluetooth-ready, with large speaker pockets that accommodate most communication systems.

At 4.8 pounds, it is on the heavier side, and riders note it can get loud at highway speeds. The AirFit inflation system lets you custom-tighten the cheek pads, which reduces wind noise for a better seal. With a 5-Year Warranty and dual DOT/ECE certification, this is a proven, no-compromise pick for the big-headed tourer.

What Wins Owners Over

  • Fit and quality are the most praised aspects — the helmet feels secure right from the start
  • Drop-down sun visor comes down further than many competitors, covering more of your field of view
  • Glasses-friendly KwikFit cheek pads make it easy to slide in eyewear without pinching

The Honest Trade-Offs

  • Noise level is mixed — some owners find it loud on the freeway, especially without earplugs
  • Size runs a bit big for its label, so a 3XL might feel looser than you expect

Reach for the T520 if: you want a dual-certified touring helmet with a drop-down visor and Bluetooth readiness that fits a 3XL head without squeezing.

Think twice if: you are sensitive to wind noise or need the lightest helmet possible — the 4.8-pound weight is noticeable on an all-day ride.

Best Value

2. LS2 Helmets Assault Full Face Motorcycle Helmet

KPA ShellPinlock Ready

A lightweight full-face that punches well above its price point.

Buyers report this helmet “swings way above its weight class,” and the data backs it up. The Kinetic Polymer Alloy (KPA) shell keeps the weight down while providing strong impact resistance, and the multi-density EPS liner works with three shell sizes to give even 3XL heads a proportional fit. The retractable sunshade eliminates the need to swap visors mid-ride.

Ventilation is well-regarded, with large adjustable chin and top vents that keep the airflow moving. The liner is fully removable and washable, a nice touch for long-term hygiene. The noise level does get mixed reviews — it is not the quietest helmet at highway speeds, but a good pair of earplugs solves that. For the price, it is hard to argue with the value.

The crowd favorite detail: the drop-down sun visor is considered a genuine convenience, and the quick-release strap is easy to use even with gloves on.

One honest caveat: some owners found the upward view limited in an aggressive tuck, so tall riders may want to try it on first.

Best for: the budget-conscious rider who still wants ECE-level safety and a drop-down sunshield in a true 3XL.

Not your pick if: absolute silence on the highway is your priority — this one lets some wind in at speed.

Classic Open Face

3. Bell Pit Boss Helmet, Black, XXX-Large

Half HelmetDOT/ECE

The half-helmet that proves a 3XL can still look sleek and feel secure.

If a full-face feels too claustrophobic, the Bell Pit Boss offers a classic half-shell design in a true XXX-Large. It weighs just 3.9 pounds, making it one of the lighter options here, which matters when you are wearing it all day. The fit is excellent — owners praise the adjustable back dial that lets you fine-tune the snugness.

Bell Pit Boss is lighter than the ScorpionEXO T520 by nearly a full pound. The drop-down tinted visor works well for cutting glare, and the fit is deep enough for oblong head shapes. The trade-off is noise: without ear coverage, wind is louder, and durability of the rear adjustment mechanism has drawn occasional criticism. It is a summer-friendly helmet that prioritizes breeze over silence.

Why Owners Stick With It

  • The adjustable fit system gets over 100 positive mentions — it is easy to dial in a perfect feel
  • Drop-down visor reduces wind resistance at speed, making it more stable than a standard half-helmet
  • Zip-in neck collar adds warmth when you want it

Who Should Look Elsewhere

  • Not for highway cruising at 70+ mph — wind noise is significant without ear protection
  • The smoked visor can feel hazy to some, and it cannot be removed

Go for this if: you want a lightweight, adjustable half-helmet for around-town cruising in a 3XL size.

Step back if: you need a full face for long highway miles or rain protection — the open design leaves you exposed.

Modern Full Face

4. ScorpionEXO R430 Full Face Street Motorcycle Helmet

Optical Class 1Bluetooth Ready
ScorpionEXO R430 Full Face Street Motorcycle HelmetCheck Price on Amazon

A modular helmet that brings flip-up convenience to the 3XL crowd without the flagship price.

The HJC C91 is a feature-rich modular (flip-up) helmet that weighs just 3.5 pounds — remarkably light for a 3XL. The polycarbonate composite shell houses a drop-down sun visor, a Pinlock-ready shield for fog-free winter riding, and glasses grooves that make it easy to wear eyewear underneath. The ventilation system channels air front-to-back to clear heat and humidity.

Owners consider it the best bargain in its price range, but the fit runs small. One size-up is almost always required — riders who measured for a 2XL ended up in a 4XL after reading reviews. The chin bar action is smooth and secure, and it is Smart HJC ready for Bluetooth integration. Noise levels are typical for a modular (some wind) but the flip-up convenience for gas stops and chats is a big win.

What You Get at This Price

  • Lightweight construction (3.5 lbs) makes it one of the easiest 3XL helmets on the neck
  • Integrated dark smoke sun visor deploys with a top-mounted slider, easy to use with gloves
  • Removable and washable liner makes long-term maintenance simple

Be Aware

  • This helmet runs small — most buyers need to go up at least one full size from their usual
  • Wind noise is noticeable on the highway; earplugs are recommended

Reach for the C91 if: you want the convenience of a modular helmet at a budget-friendly cost and you are willing to size up for the right fit.

Think again if: you are not prepared to deal with running slightly smaller than the tag suggests — the sizing makes it tricky without trying on first.

Dual Sport

5. Bell Powersports MX-9 Adventure MIPS Motorcycle Helmet

MIPS ProtectionDual Sport

A dual-sport helmet with MIPS that goes from singletrack to asphalt without missing a beat.

The MX-9 Adventure MIPS is built for the rider who wants one helmet for dirt and street. It features MIPS (Multi-directional Impact Protection System), a low-friction layer inside the shell that reduces rotational forces on the brain during angled impacts. The design includes an integrated anti-fog, anti-scratch faceshield that flips up to leave room for goggles on the trail.

The weight is reasonable at 3.75 pounds, and the Velocity Flow ventilation keeps air moving. Owners note it is surprisingly lightweight and comfortable for its class, but the visor catches wind on the highway, and the vents cannot be fully closed — so water can sneak in during a downpour. It is a specialized tool best for adventure riding, not long-distance tarmac tours.

The standout detail: the MIPS layer adds real safety tech at an accessible price point, and the removable/adjustable visor gives you a stealth street look when you take it off.

The downside: fogging can be an issue in cold or wet conditions; a Pinlock insert is recommended by owners to keep the view clear.

Best for: serious adventure riders who split their time between unpaved trails and paved roads and need MIPS protection in a 3XL shell.

Not the right call if: you spend most of your time on the highway — the wind-catching peak and fixed-open vents make it less comfortable at speed.

Mid-Range Modular

6. LS2 Helmets Advant Modular Helmet

180° RotationECE P/J Certified

A modular that rotates the chin bar a full 180 degrees, transforming from full-face to open-face in one move.

LS2’s Advant Modular brings their best 180-degree rotating chin guard to the 3XL size. The Kinetic Polymer Alloy (KPA) shell keeps the weight at around 1,600g (approximately 3.5 lbs), though the listed shipping weight is 6 pounds with packaging. It is ECE “P” and “J” certified, meaning it is tested and approved in both full-face and open-face configurations.

The built-in sun shield and Pinlock-ready faceshield with included insert are practical touches. It runs small — owners unanimously advise ordering at least one size larger than the sizing chart suggests. The fit is round-profile friendly, so long-oval heads may find the cheek pads snug. Wind noise is moderate at speed, but the 180-degree flip makes it highly convenient for frequent stops.

The Best Parts

  • 180-degree rotating chin guard makes the helmet incredibly versatile — ride open or closed
  • Pinlock insert included at no extra charge, a real plus for fog-prone climates
  • 3D laser-cut cheek pads create a comfortable, custom-like feel with no hot spots

Consider Before Buying

  • Runs small — you almost certainly need to size up, sometimes by a full two sizes
  • The chin strap buckle can be fiddly to fasten, especially with gloves on

Go for the Advant if: you want a true 180-degree modular for mixed city and highway use, and you are willing to size up for the fit.

pass on it if: you have a long-oval head shape — this helmet is tune for rounder profiles.

Street Fighter

7. ScorpionEXO Covert FX Full Face Motorcycle Helmet

Ultra-Light CompositeECE 22.06

A lightweight street-fighter that sheds ounces without skimping on safety ratings.

At just 2.9 pounds in a medium, the Covert FX is the lightest full-face helmet on this list — the TCT-Ultra Composite shell and hand-laid carbon fiber construction are a big part of that. It is certified to both DOT and the newer ECE 22.06 standard, which requires a wider range of impact testing than the older 22.05. The aero-tuned ventilation system includes a dual-position mouth vent that acts as a defroster.

Owners praise the quietness and airflow — it is consistently described as the quietest helmet they have worn, and the ventilation keeps things cool without being drafty. The fit is tight initially but breaks in beautifully, and the KwikFit cheek pads accommodate glasses. An extra dark smoke shield is included in the box, a nice bonus for day-night versatility.

The headline stat: at 2.9 lbs, it is dramatically lighter than the ScorpionEXO T520 (4.8 lbs), making it a necksaver for long rides.

The honest catch: speaker pockets are on the smaller side — some owners had to cut foam to fit larger JBL units, and the front vent control is inside the chin, awkward to operate while riding with gloves.

Best for: the rider who prioritizes low weight, modern safety certification, and a quiet ride above all else.

Not for you if: you need a built-in sun visor — the Covert FX relies on included tinted shields for glare reduction.

Carbon Adventure

8. KLIM Krios Pro Adventure Motorcycle Helmet

Full Carbon FiberFID-LOCK Strap

A carbon-fiber adventure helmet that feels like a motocross lid on the street.

The KLIM Krios Pro uses a hand-laid full carbon fiber shell with tune resin distribution to save weight, and Koroyd structures that crush homogenously for better impact absorption. The result is a helmet that owners call the “lightest helmet I have ever owned” — just over 3 pounds, making it exceptionally comfortable for multi-day trips.

The transition lens is the most praised feature — it automatically darkens in bright light and clears up when the sun goes down, so you never have to swap shields. The FID-LOCK strap closure system is magnetic and easy to operate one-handed. There are no dedicated speaker pockets, so earbuds are the route for audio, and the peak can squeak in the wind. It is quiet with the visor down, but mixed at higher speeds when the peak catches airflow.

Why It Is a Top Pick

  • Full carbon fiber shell and Koroyd impact structures make it incredibly light and strong
  • Transition lens technology eliminates the need to carry a second shield
  • FID-LOCK strap is the easiest to use in this list — one quick motion to secure

The Fine Print

  • No built-in speaker pockets — you are limited to earbuds or aftermarket solutions
  • Fit is mixed — some owners find it tight on the forehead, requiring a careful break-in period

Reach for the Krios Pro if: you want a premium, ultra-light adventure helmet with a self-tinting visor and the tightest safety engineering available.

Look elsewhere if: you need integrated Bluetooth speaker pockets or you have a budget that cannot stretch to the premium price tag.

High-End Modular

9. LS2 Helmets Advant X Modular Helmet

180° Rota Polymer Alloy) is a composite blend often found on mid-range LS2 helmets, while full carbon fiber is the premium option — lighter and stronger, but significantly more expensive. Multiple shell sizes (like “3 Shell Sizes” on the ScorpionEXO T520) mean the shell actually scales up for larger heads, so a 3XL does not just use thicker padding stuffed into a medium shell.

Safety Certifications

DOT (Department of Transportation) is the legal minimum in the US. ECE 22.06 is a tougher European standard that tests more impact points and rotational forces. A helmet with both certifications has passed a wider battery of tests. MIPS (Multi-directional Impact Protection System) is an additional layer inside the helmet that reduces rotational energy to the brain during angled impacts. Snell certification is another voluntary standard that often requires even higher energy absorption, like the ScorpionEXO R430’s Snell rating.

FAQ

How do I know if I need a 3XL helmet?
Measure the circumference of your head about one inch above your eyebrows using a soft tape measure. Most brand size charts consider 24.5 to 25.5 inches (62-65 cm) as 2XL, and anything above that into 3XL. If your measurement falls at the top of the 2XL range, you may still need a 3XL depending on the brand’s specific fit — some, like the HJC C91, run small and require sizing up.
Is a modular helmet as safe as a full-face?
Yes, when it meets the same certifications. The LS2 Advant models carry ECE “P” and “J” ratings, meaning they are tested and approved in both the closed (full-face) and open configurations. However, some helmet purists argue that a solid full-face is inherently stronger because there is no hinge mechanism. A modular that meets ECE 22.06 or DOT standards is still very safe for street riding.
Why do some helmets list 6 pounds but feel lighter?
The “Item Weight” on Amazon listings often includes the packaging, not the helmet alone. For example, the LS2 Advant series is listed at 6 pounds, but the actual helmet weight is around 1,600g (approximately 3.5 lbs). Always check the product description or specifications for the actual helmet weight to get an accurate idea of what you will wear.
Can I use Bluetooth speakers with any 3XL helmet?
Most modern helmets designed in the last few years include speaker pockets — cutouts in the EPS foam that accommodate 50mm or similar-sized speakers. The ScorpionEXO T520 and HJC C91 both have “Bluetooth Ready” pockets. The KLIM Krios Pro does not have dedicated pockets, so you need to use earbuds or install a thin aftermarket kit. Always check the specs for “speaker pockets” if audio is important to you.
How do I fix a helmet that is a little too tight?
Most full-face helmets have removable cheek pads that come in different thicknesses. Brands like ScorpionEXO sell optional thinner cheek pads separately. You can also try removing the liner and gently stretching the EPS by hand, but this is not recommended by manufacturers. The safest route is to exchange for the next size up — and if you are between sizes, go larger because you can always use thicker pads.
What is the difference between 3XL and 4XL?
It varies by brand, but generally a 3XL fits a head circumference of about 25.5 to 26.5 inches (64-67 cm), while a 4XL goes up to 27 inches (68-69 cm) or more. The ScorpionEXO R430 is available up to 4XL, making it one of the largest options on this list. Always check the specific brand’s size chart before ordering.
Are carbon fiber helmets worth the extra cost?
For riders who spend long hours on the bike, yes. The weight savings — like the KLIM Krios Pro at just over 3 pounds vs. the ScorpionEXO T520 at 4.8 pounds — directly reduces neck fatigue. Carbon fiber is also stiffer per gram than polycarbonate, which can mean better impact absorption. The trade-off is price: carbon fiber helmets typically cost two to three times more than a polycarbonate equivalent.
How do I care for my helmet liner?
Most modern helmets have a removable and washable comfort liner. Simply unclip the liner from the EPS shell and hand-wash it in mild soap and lukewarm water. Air-dry it completely before reinstalling. The ScorpionEXO R430 and LS2 Assault both feature fully removable, machine-washable liners — check the product description for the specific care instructions.

Final Thoughts: The Verdict

Across the board, the xxxl motorcycle helmet winner is the ScorpionEXO T520 because it nails the balance of fit, safety (DOT/ECE), and touring-friendly features like the drop-down visor and Bluetooth readiness at a price that makes sense. If you want a lighter budget pick that still impresses, grab the LS2 Assault. And for premium modular versatility, the LS2 Advant and its carbon sibling are the ones to reach for.
