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 Boxers from Sabelt is designed to provide FIA-level protection in a comfortable package.
Like the rest of the UI-300 line of long underwear, these shorts are 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. A wide elastic waist and an athletic fit prevent bunching. Per FIA requirements, there is no front fly opening to compromise safety. Features a black-on-white Sabelt logo on the front of the waistband and an FIA 8856-2018 homologation tag on the back.
