SFI 3.3 Certified And Priced For The Weekend Racer. OMP OS40 Long Bottom Sport Nomex® underwear is breathable and comfortable for those long weekend days.
OMP OS40 Nomex® long bottoms provide a dramatic increase in protection when worn with a driver's suit. Flame resistant underwear and socks are required by many
race sanctioning bodies. This OMP long underwear bottom is made of a very comfortable single layer of soft knit Nomex®. This is not the rough "waffle weave" fabric!
SFI 3.3 Rated. Natural Optical White color to stay cool.

The OS40 Long Bottoms breathable suits and underwear facilitate the body thermoregulation, thanks to the innovative weave of the inserts, strategically positioned, that allow for high breathability whilst still maintaining their own fire-retardant properties (according to the FIA standard 8856-2000).
