Oumurs Adult ATV Dirt Bike Helmet Kit — 806 Matte Black, Size L, DOT-Certified & Ventilated

OUMURS Adult ATV Dirt Bike Helmet is a DOT-FMVSS-218 certified off-road helmet sold as a kit with goggles, gloves, and a mask for safer, more comfortable motocross and ATV riding.

This helmet kit combines an impact-resistant ABS shell and EPS inner foam with practical accessories so riders can hit trails with clearer vision and better protection. Designed for off-road, motocross, downhill, and ATV use, the OUMURS helmet balances ventilation, sun protection, and easy fastening to keep you comfortable during long rides.

What safety standards and materials does this helmet use?

The OUMURS helmet meets DOT FMVSS-218 certification and uses a durable ABS outer shell backed by EPS shock-absorbing foam. Those construction choices are common for motorcycle-rated helmets and offer a reliable compromise between weight, strength, and impact attenuation.

• DOT FMVSS-218 certified for road-legal motorcycle safety compliance
• Durable ABS outer shell resists abrasion and impact
• EPS inner lining designed to absorb and dissipate energy
• Quick-release chin buckle for secure, rapid fastening

How does ventilation and sun protection perform on warm or sunny rides?

Multiple air vents channel fresh air through the helmet to reduce heat buildup and keep you cooler on long runs. An adjustable sun visor blocks glare and sun rays while preserving visibility, and the vent design also helps lower wind noise.

• Strategically placed intake and exhaust vents for continuous airflow
• Removable/adjustable visor to shield eyes from sun and debris
• Optimized venting reduces wind noise for a quieter ride

What accessories come with the helmet, and how do they help?

Each kit includes goggles, gloves, and a protective face mask so you can ride straight out of the box with basic gear coverage. The goggles improve dust and UV resistance, the gloves protect hands and enhance grip, and the mask helps block wind and particulate matter.

• Goggles: windproof and UV-resistant lens for clearer vision
• Gloves: tactile grip and hand protection during off-road use
• Face mask: dust and wind protection to improve comfort
• Everything sized and packed with the helmet for convenience

Which helmet sizes are available and how do I choose my fit?

OUMURS offers a range of adult sizes from M through XXL; measure head circumference to pick the best fit. A correct fit should feel snug without pressure points—if between sizes, choose the larger size and use the helmet’s straps and padding for final adjustment.

• Adult M: 570–580 mm (22-1/2"–22-7/8")
