Sabelt UI-600 Slim Fit Underwear Top, FIA 8856-2018

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-600 Slim Fit long-sleeve underwear top 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! An innovative knitting process minimizes seams, and the few remaining seams are flat-sewn to minimize pressure points. The athletic cut makes full use of the two-way stretch, fitting you like a second skin to avoid bunching. The top has a mock turtleneck collar and low-profile wrist cuffs. Raglan sleeve design moves the shoulder seams out from under your harness or HANS collar. Choose White (off-white heather) or Black. FIA 8856-2018 approved.
