Nomex Underwear
Nomex racing underwear is a critical part of a complete fire-protection system, not just an optional extra. These base layers are designed to be worn under your suit to add valuable seconds of protection while also helping manage heat and moisture during long sessions. At Capaldi Racing, we carry FIA and SFI-rated Nomex tops, bottoms, socks, and balaclavas from trusted brands, chosen for their comfort, stretch, and durability in real track conditions. Use this page to compare weights, fits, and certification levels so you can build a base layer kit that matches your series rules, your suit, and the demands of your racing program.
