Brand: OMP Racing Products
Fire-resistant undergarments provide a dramatic increase in protection when worn with a driver's suit. Flame retardant underwear and socks are required by many race sanctioning bodies. Even if your racing organization doesn't require it, a protective base layer provides one more layer of safety that cotton or synthetic skivvies can't.
The ONE Evo underwear from OMP is made of a very comfortable single layer soft knit fire retardant fabric. The special tubular knitting process minimizes the number of seams, and the few seams that remain are so flat you'll swear the shorts are seamless. This is the same high-tech construction used in OMP underwear supplied to F1 teams.
These boxer-briefs feature a wide elastic waist and an athletic fit to prevent bunching. No front fly opening to compromise safety. Black with a grey OMP logo on the waistband. FIA 8856-2018 homologated.
Note: These shorts have a slim, athletic cut with increased elasticity to avoid bunching and bagginess. They are designed to be a tight stretch fit.
