Sparco’s Delta RW-6 line of fire-retardent underwear is constructed using a “body-size” process wherein the garment is woven as a single piece with no seams at the sides. This process allows for the elasticity to be customized throughout the shirt, offering a second-skin fit for superior comfort under the racing suit. The mid-length “Bermuda-short” Boxers are perfect for races that do not require FIA/SFI underpants. A mesh structure is strategically applied to increase comfort and breathability in specific areas of the shorts. Elasticized, ribbed mesh waist band supports the flame-retardent cotton/modacrylic fabric that is naturally soft and breathable.
