Alpinestars TECH ZX Short Boxer Briefs, FIA

Brand: Alpinestars Racing Safety Equipment

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 Tech ZX underwear from Alpinestars is made of a very comfortable single layer soft knit containing Lenzing FR®, a permanently flame-resistant natural fiber that insulates against extreme heat while allowing your skin to breathe. This is the same fabric used in Alpinestars underwear supplied to F1 teams.

These boxer-briefs feature an elastic waist and an athletic fit to prevent bunching. No front fly opening to compromise safety. Choose Black or White, each with a contrasting "A-star" logo on the front just below the waistband. FIA 8856-2018 homologated.
