The Alpinestars Race V3 Underwear Bottoms, SKU ALS475-412, are FIA 8856-2018 certified racing underwear designed for drivers who want a reliable, comfortable base layer that does not add significant bulk under a race suit. They are the entry point to Alpinestars’ FIA underwear range and represent a practical starting choice for club and single-seater competitors.
The fabric uses Lenzing FR fibres, which are a viscose-based fire-resistant material that feels notably softer against the skin than pure Nomex. The two-layer construction adds depth to the flame barrier without creating the stiffness that single-layer fire-resistant fabrics often have. Flat seams eliminate raised ridges that cause pressure points during prolonged seat time. The fit is relaxed by the standards of the range, which suits drivers who find the close-cut ZX Evo underwear too restrictive on the thigh and knee.
The Race V3 Bottoms come in grey or anthracite in sizes S through XXL. The grey and anthracite colour palette is specific to the original Race V3 line; the 2024 update of the same model (SKU ALS475-712) comes in black and white and carries the additional SFI 3.3 approval for use at American-series events. If you race in UK club championships, either version satisfies the underwear requirement. At £76, these sit below both the 2024 model and the ZX Evo V2 Bottoms at £101.50, which use a higher-performance moisture-management construction for longer stints. We carry Race V3 Underwear Bottoms from our Nottingham warehouse; the standard lead time is 2 to 3 working days.
