Oumurs Adult Dirt Bike Helmet Matte Black M — Full-Face ABS Shell with EPS Liner & Goggles Kit

The OUMURS Adult Dirt Bike Helmet is a full-face, off-road helmet kit that combines an ABS shell, EPS liner, adjustable sun visor, goggles, gloves and mask for safer, clearer riding.

This helmet package is built for riders who want a ready-to-ride dirt bike or ATV solution: a DOT-style, motocross-shaped helmet constructed from a durable ABS outer shell and energy-absorbing EPS liner, plus wind-blocking accessories to protect eyes, hands and face. It balances ventilation, retention security and sun protection so you can focus on the trail or track.

How does the helmet protect my head during off-road use?

The helmet’s hard ABS outer shell disperses impact forces while the EPS inner liner absorbs shock to reduce transmitted energy. Together these layers form the common dual-structure used in recreational motorcycle helmets to manage impact and abrasion on rough terrain.

• Rigid ABS shell for external impact resistance
• EPS liner for impact energy absorption
• Full-face motocross profile to shield chin and jaw
• Double D-ring chin strap keeps the helmet secured under load

Will the goggles, gloves and mask make a measurable difference on the trail?

Yes — the included goggles block wind, dust and UV to maintain clear vision, while the gloves improve grip and the face mask reduces direct wind exposure. These accessories turn the helmet into a more complete protective set for varied trail conditions.

• Goggles: anti-wind and UV-resistant lens for clearer sightlines
• Gloves: added grip and abrasion protection for hands
• Mask: windproof barrier to reduce inhaled dust and chill
• All included so you can ride immediately after purchase

How does ventilation and noise control perform in warm weather?

Multiple air vents are integrated into the shell to channel fresh air over the head and out through exhaust ports, helping to prevent overheating on long or intense rides. The vent design also helps reduce wind noise, making for a more comfortable ride at higher speeds.

• Front intake vents draw cool air in
• Rear exhaust passages expel warm air
• Vent routing designed to lower wind noise
• Better comfort for hot-weather and extended sessions

Which sizes are available and how should I choose my fit?

The OUMURS helmet comes in four adult sizes; measure head circumference at the widest point above the ears to match the correct size. A proper fit should be snug without pressure points and the chin strap should fasten securely using the double D-ring system.

• Adult-M: 570–580 mm (22-1/2"–22-7/8")
• Adult-L: 590–600 mm (23-1/4"–23-5/8")
• Adult-XL: 610–620 mm (24"–24-3/8")
• Adult-XXL: 620–630 mm (24-3/8"–24-3/4")

Who is this for: The OUMURS Adult Dirt Bike Helmet kit is aimed at recreational and commuter riders who want an affordable, ready-to-use off-road helmet package. It suits motocross and ATV riders seeking a combination of impact management, sun protection and dust control, and riders who prefer a packaged solution (helmet plus goggles, gloves and mask) rather than sourcing each accessory separately. If you need certified competition equipment or specialized racing gear, check the appropriate standards and certifications for your event before purchasing.
