Sparco RW-4 Boxers

Sparco's entry-level RW-4 line of underwear is optimized for both comfort and protection while maintaining a budget price. Although not FIA or SFI approved due to their short length, fire resistant boxer shorts are great for adding protection on hotter days when rated-protection is not needed. Using Sparco's classic soft-touch fire resistant fabric, the regular fitting shorts are comfortable for all body types and offers excellent breathability.
