The Alpinestars ZX Evo V2 Underwear Bottoms, SKU ALS475-5520, are FIA 8856-2018 certified racing underwear from the ZX Evo range, developed for drivers who run warm, compete in endurance formats, or simply find the entry Race V3 underwear too heavy and hot for sustained use. At £101.50, they cost more than the Race V3 Bottoms but use a construction specifically designed for heat regulation rather than just fire resistance.
The ZX Evo V2 construction optimises the driver’s core temperature rather than treating fire resistance and comfort as separate requirements. The fire-resistant fibre used is specifically chosen for its heat transfer properties alongside its flame resistance, so the material actively moderates how much body heat is retained rather than simply not burning. The compression-fit cut applies a measured pressure to the legs that promotes blood circulation and reduces the fatigue that develops in the quads and hamstrings over multiple stints without restricting movement in the hip flexors or behind the knee. Flat seams throughout.
The ZX Evo V2 Bottoms come in black or white in three size bands (XS-S, M-L, XL-XXL) rather than the five individual sizes of the Race V3. Most drivers find the three-band sizing works well for the underwear because the compression element of the fit accommodates variation within the band. At £101.50, they sit between the Race V3 Bottoms at £76 and the more recent ZX Evo V3 generation. For a matched set, the Race V3 Long Sleeve Top at £106 can be paired with these bottoms for a mixed Race V3/ZX Evo combination where budget is a factor. We hold the ZX Evo V2 Underwear Bottoms from our Nottingham warehouse; lead time is 2 to 3 working days.
