Impact Racing Super Charger Side Air Helmets offer many of the popular features and benefits of Impact's Top Air version except with a side inlet for racers looking for the fresh air port to be directed onto their face or are limited by the overhead chassis clearance. Designed with an oversized wrap-angle eye port, the Impact Racing Super Charger Side Air Helmets offer a panoramic field of vision and features a heavy-duty 1/8" polycarbonate shield available in a variety of anti-fog and tinted options. Impact Racing Super Charger Side Air Helmets also feature Impact's exclusive "Intelligent Gray Matter" padding, which is a single-piece, variable-density inner liner. This Intelligent Gray Matter is upholstered in fire retardant soft-knit Nomex, and also includes interchangeable cheek pads for a customized fit.
