Brand: Sabelt
Most racing organizations do not require "Personal Underwear" to be worn beneath fire-resistant long underwear, but the FIA requires that any PU must meet the FIA 8856-2018 homologation standard. The UI-300 Bra from Sabelt is designed to provide FIA-level protection in a comfortable package.
Like the rest of the UI-300 line of long underwear, this bra is constructed of a soft-knit blend of inherently fire-retardant fibers. The blend includes a high percentage of natural fibers for a soft, natural feel against your skin. Manufacturing techniques developed for F1 drivers' underwear are carried over, including variable-density knitting, which provides support in key areas and a more open mesh for breathability in others. The special tubular knit means no side or back seams. A wide elastic band at the base and racer-back shoulder straps keep the garment from shifting. Features a black-on-white Sabelt logo on the bottom front and an FIA 8856-2018 homologation tag on the back.
