Collection: Racing Underwear

FIA & SFI-CERTIFIED BASE LAYERS FOR AUTO RACING BY BELL, OMP & HRX 

Wearing high-performance fireproof underwear beneath your racing suit is not optional — it’s imperative. For your suit to deliver full flame-resistance and thermal protection, you must pair it with FIA- or SFI-homologated underwear. Never wear synthetic athletic gear or untreated cotton beneath a fire suit. Even if your club, track, or sanctioning body doesn’t enforce base layer compliance, your safety is always in play.

This collection includes fireproof tops, bottoms, socks, and balaclavas from Bell, OMP, and HRX — all certified to FIA 8856-2018 and/or SFI 3.3. Designed for intense auto racing disciplines like road racing, rally, drag, and endurance, these base layers offer full-body flame protection, heat stress relief, and driver-focused comfort under pressure.
