Alpinestars ZX EVO v3 Bottom, FIA 8856-2018, SFI 3.3

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 ZX EVO series long underwear 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! The ZX EVO v3 series features more Lenzing in the blend for even greater comfort than the Alpinestars Race series.

Bottoms feature a very narrow elastic waist for comfort. The fabric is knit to be extra-stretchy because the fit is tight. No front fly opening to compromise safety. A distinctive "jacquard" (ask your wife) pattern, as seen on Williams F1 drivers, does more than just provide a racy look, it actually promotes sweat wicking and ventilation. Choose White with light grey pattern or Black with dark grey, each with a contrasting "A-star" logo on the front of the waistband. FIA 8856-2018 homologated and SFI 3.3 approved.
