Description
Brand: Sabelt
Fire-retardant undergarments 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.
The Sabelt UI-500 long underwear bottom is made of a very stretchy knit single layer blend of Nomex® and Lenzing FR (a plant-based, moisture-wicking, inherently fire-resistant fiber). This is not the old rough “waffle weave” fabric!The athletic cut makes full use of the two-way stretch, fitting you like a second skin to avoid bunching.Bottoms feature a very narrow elastic waist and no front fly opening to compromise safety.Black color.FIA 8856-2000 approved.
