The 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. 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, with finer stitching in the ankles for increased comfort.
