1Storm Adult Motocross Helmet HF801 Sonic Blue - Lightweight Full Face

Our review of the 1Storm Adult Motocross Helmet HF801 Sonic Blue finds it best suited for casual riders, BMX and dirt-bike enthusiasts who want DOT-approved protection without spending a premium. The single biggest reason to buy is the combination of a lightweight, aerodynamic thermoplastic alloy shell and a heavily cushioned interior that keeps the helmet comfortable for longer rides. Fit runs slightly small for some users, so riders who sit at the top of a size range should try before committing, but for many the helmet delivers solid looks, comfort, and value.

Key Features

• XL sizing: The XL shell (59-60 CM, 23.2/23.8 in) is aimed at larger adult heads and reduces pressure points for riders who need extra room.
• Lightweight shell: The aerodynamic thermoplastic alloy construction keeps weight down while maintaining a durable outer surface for riding at speed.
• Comfortable interior: Heavily cushioned padding provides day-long comfort and helps stabilize the helmet on bumpy trails.
• Removable padding: The interior pads are washable and removable, which makes it easy to keep the helmet fresh after sweaty sessions.
• DOT certified: Meets Federal Motor Vehicle Safety Standard 218 (FMVSS 218), offering required safety compliance for street and trail use where DOT approval is needed.
• Glossy UV finish: The Sonic Blue glossy coating resists UV fading and keeps the helmet looking sharp ride after ride.

Who It's For

The 1Storm HF801 is ideal for recreational motocross, BMX, ATV and quad riders who want a full-face design with DOT approval at an affordable price. It suits adults who prioritize a lightweight feel and a comfortable interior over premium ventilation or brand-name features.

Riders seeking a precision race helmet with custom fit options or those who need multiple size choices should look elsewhere, especially if they typically require sizes larger than XL or consistently find helmets to run small. For everyday trail use and neighborhood riding it is a practical, value-led option.
