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-100 long-sleeve underwear top is made of a very comfortable soft knit single layer blend of 50% Nomex® and 50% Viscose (a plant-based, moisture-wicking, inherently fire-resistant fiber). This is not the old rough "waffle weave" fabric! The cut is slightly generous for maximum comfort and less binding. The top has a low collar (between a crewneck and a mock turtleneck) and elastic knit wrist cuffs. Updated sleeve design moves the shoulder seams farther away from your harness or HANS collar. Available in bright White or black. FIA 8856-2000 approved.
