Race Bottom V3 XX-Large White FIA

The Alpinestars Race Bottom V3 XX-Large White FIA is a professional-grade racing underwear bottom engineered for drivers who demand fire-resistant protection in the cockpit. Designed to meet FIA (Fédération Internationale de l'Automobile) safety standards, this garment is essential for circuit racing, endurance events, and any competitive motorsport application where driver safety regulations require certified flame-resistant base layers. The white colorway offers excellent visibility and blends seamlessly with any racing suit color scheme.

Constructed from Lenzing FR fabric, the Race Bottom V3 delivers superior fire resistance while maintaining comfort during extended driving sessions. Lenzing FR is a bio-based flame-resistant fiber that provides inherent protection without chemical treatments, ensuring durability through repeated washing and use. The V3 iteration reflects Alpinestars' latest ergonomic refinements, featuring a form-fitting cut that minimizes bulk beneath racing suits and reduces heat buildup in the driver's compartment. Seamless construction and strategic panel placement eliminate chafing points, critical when confined in a racing seat for hours.

Professional racing drivers, amateur circuit competitors, and FIA-regulated event participants benefit most from this race-specific garment. It pairs with Alpinestars racing suits and other FIA-approved race wear to create a complete protective system that satisfies tech inspection requirements at sanctioned events. The XX-Large sizing accommodates drivers requiring extended fit without compromising the close-fitting design critical to performance motorsport. Single garment purchase provides one race bottom; layering with matching race tops creates full FIA compliance for all motorsport disciplines.
