LS2 Gates II Full Face MX Helmet 3XL

The LS2 Gates II is built with a KPA shell designed for energy management and impact protection, a critical consideration for riders who need a larger shell. Its wide eye port accommodates most popular goggles (goggles not included), helping maintain clear visibility during off-road sessions. An emergency release cheek pad system adds a layer of safety for quick mobility by responders in case of an incident. The helmet’s 3XL sizing ensures a more comfortable fit for riders with larger head measurements while preserving the snug seal around the jaw and cheeks necessary for protection.
In practice, the Gates II balances a sturdy shell with practical features suited to motocross and dirt track riding. Riders should verify their head circumference against LS2’s sizing charts to ensure an accurate 3XL fit, and consider venting performance during hot-weather rides. The design emphasizes safety without compromising visibility or comfort for larger head sizes.
O’Neal 5SRS Helmet 3XL

The O’NEAL 5SRS helmet uses an ABS shell combined with a Coolmax liner, delivering a comfortable, breathable ride. The ultra-plush removable/washable padded liner enhances long-term comfort, essential for riders that wear a helmet for extended periods. The listed weight for a large size is about 1380 grams (±50), which helps riders assess any potential head fatigue over longer sessions. This model’s 3XL option provides a roomy fit while keeping the protective seal needed for aggressive dirt riding.
For big-headed riders, the 3XL configuration of the 5SRS offers additional comfort without sacrificing safety. The liner system supports repeated washing, helping maintain hygiene on longer trips. When choosing sizing, consult the O’Neal sizing chart to confirm the best 3XL fit, especially if you wear high-cushion or volume-filled goggles beneath the helmet.
Daytona Glide Helmet – Silver Metallic 3XL

The Daytona Glide Helmet is a lightweight option designed for dirt riding, weighing about 1550 g ± 50 g and DOT certified for FMVSS 218 safety standards. It features an outer anti-fog electric heated dual-pane shield to prevent fogging, complemented by an inner retractable smoke shield that acts like built-in sunglasses for sun glare control. The 3XL size provides the needed room for larger heads while maintaining a secure fit around the cheeks and jawline, a crucial factor for protective performance in rough terrain.
Ease of use is another highlight: a nylon strap retention system and a quick-release lock enable easy detachment with one finger, while adjustable chin vents and a chin curtain help regulate airflow and reduce wind noise. For riders who want a combination of safety, visibility, and practical features in a single 3XL helmet, the Daytona Glide offers a balanced option with rugged, dirt-focused design attributes.
OUMURS Dirt Bike Helmet Gray XL

The OUMURS gray XL helmet targets larger fits with size options that include Adult-M, Adult-L, Adult-XL, and Adult-XXL, and it meets DOT FMVSS-218 safety standards. It is constructed from an ABS shell with EPS linings, providing a solid level of protection suitable for dirt bike and ATV use. The package includes goggles, gloves, and a mask, offering an all-in-one setup for riders who want integrated gear to complement their helmet and shield their face from wind, dust, and debris.
In addition to safety, this helmet emphasizes windproofing and UV resistance, with an adjustable sun visor to tailor visibility across different lighting conditions. The XL sizing gives riders a broader option beyond standard sizes, but potential buyers should confirm their head measurements against the provided size chart to ensure a correct, comfortable fit for longer rides.
OUMURS Dirt Bike Helmet Black Skull XL

The Black Skull XL variant from OUMURS follows the same design philosophy as the gray model, offering a large-fit option that includes goggles, gloves, and a mask, along with DOT/FMVS-218 safety compliance. The ABS shell and EPS liner provide reliable protection for dirt riding, while windproofing and UV resistance help maintain comfort during sunny or dusty sessions. The XL sizing makes this model accessible to riders who need more room than standard sizes, though customers should verify fit with their own measurements to avoid pressure points at the temples or forehead.
With similar features to the gray version, this helmet emphasizes practical on-trail use and all-in-one gear packages. Riders prioritizing a roomy fit and included accessories will appreciate the combination of protection, convenience, and the forgiving sizing the XL option provides for bigger heads.
Buying Guide
Key considerations when selecting a dirt bike helmet in large sizes include fit, safety, comfort, and practical features that matter during off-road riding. The following points help compare these top options and identify what matters most for 3XL or near-3XL sizing.
- Size availability and measurement: A helmet labeled 3XL is ideal for larger head circumferences, but not all models list 3XL. Check exact head measurements and compare to sizing charts. For riders requiring up to XXL, consider models such as OUMURS with XL-XXL options.
- Safety standards: Look for DOT FMVSS-218 certification or equivalent. All helmets listed here meet recognized safety standards, which is essential for dirt riding in unpredictable conditions.
- Shell material and liner: ABS shells with EPS liners are common for dirt helmets, balancing protection with weight. Removable/washable liners improve hygiene and comfort during long sessions.
- Visor and visibility: Some models include retractable sun visors or anti-fog/dual-pane shield systems. Heated shields or integrated shields help maintain clarity in varying weather and light conditions.
- Ventilation and comfort: Adequate venting reduces heat buildup and fatigue. Look for chin vents and well-placed exhausts that don’t compromise protection or fit.
- Goggles compatibility: If you wear goggles, ensure the helmet has a sufficiently wide eye port and compatible interior geometry to avoid pressure on the goggles.
- Accessory bundles: Some helmets come with bundled goggles, gloves, and masks, which can add value. Assess whether these extras align with your riding needs.
- Weight considerations: Heavier helmets may offer more protection but can cause neck strain on long rides. Compare weights (when provided) to find a balance between safety and comfort for your size.
- Maintenance and care: Removable liners and easy cleaning extend helmet life. Follow manufacturer care instructions to preserve fit and protection.
- Price-to-value: Bigger sizes can carry a premium; weigh the features, safety certifications, and comfort against price to determine overall value.
In summary, the best 3XL or near-3XL options combine solid safety standards, a comfortable interior, and features that support visibility and weather conditions on dirt trails. For riders needing extra room, models from LS2, O’Neal, and Daytona offer strong protection with 3XL sizing, while OUMURS variants provide generous XL-XXL options with bundled gear for added value. Always verify sizing with each brand’s chart and, if possible, try on helmets to ensure a proper, safe fit before riding.
