Traqgear's top of the line performance base layer, the Ultra Underpant Bottoms are engineered to stay comfortable and dry in the toughest race conditions. The perforated AirMesh fabric offers superior breathability while maintaining an SFI certification for fire protection. Lightweight and comfortable, the Ultra bottoms quickly wick sweat away to help keep you cool on the hottest days. With a soft feel that rivals that of Cotton, the pants have a contoured shape specifically designed for driving with a no-rise elastic waistband and compression fit.
