Staring with Traqgear's top of the line Ultra Long Sleeve performance base layer, the Ultra Liquid Cooled Top adds over 50 feet of cooling tubing by F.A.S.T. to help combat heat stress. The perforated AirMesh fabric offers superior breathability while maintaining an SFI certification for fire protection. Lightweight and comfortable, the Ultra shirt quickly wicks sweat into the air to help keep you cool on the hottest days. With a soft feel that rivals that of Cotton, the shirt has a contoured cut specifically designed driving with an extended back and compression fit.
