Alpinestars RACE v3-24 Lenzing Bottom, FIA 8856-2018, SFI

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.

The Race v3 long underwear bottom from Alpinestars is made of a very comfortable single layer soft knit blend of fire-retardant synthetic aramid fibers and Lenzing FR®, a permanently flame-resistant natural fiber that insulates against extreme heat while allowing your skin to breathe. This is not the rough "waffle weave" fabric! This is the same fabric used in Alpinestars underwear supplied to F1 teams.

Bottoms feature a very narrow elastic waist and a slightly relaxed fit for extra comfort. 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. Tagged with dual FIA 8856-2018 and SFI 3.3 certifications.

Note: The 2024 Edition of the Race v3 bottom is cut to be a much closer and more athletic fit than the previous v3 generation. The addition of elastane fiber in the 2024 weave makes the fabric much more elastic so it can fit like a second skin. If you are between sizes, we recommend trying the larger size.
