Impact RACE Offset Air Draft OS20 Helmet With OFFROAD Wired Helmet Kit is built for comfort, safety, and overhead clearance. The OS20 features a 20° offset fresh air hose inlet that channels air into the helmet, ensuring cooling from top down and away from the eyes. The helmet comes with standard-width removable cheek pads, but offers a variety of thicknesses to customize fit. Helmet sizes range from XS to XL. The helmet liner, called Gray Matter, is covered in fire-resistant fabric. The OS20 has a large eye port for excellent visibility on the track, shielded by a durable 1/8-inch polycarbonate shield. The helmet is made in the USA with proprietary American space-age Carbon-Kevlar tri-weave composite shell construction. The chinstrap is fire-retardant Kevlar with a locking dual D-ring design. The helmet weighs 4.5 lbs and comes with a 3 position detent standard clear shield.
