CRAMSTER HyperFlex base layer upper, a long-sleeve riding top worn next to the skin under riding gear on hot rides. Its fabric offers 4-way stretch, breathability, odour control and sweat-wicking comfort, which keeps the rider cooler and fresher on hot-weather rides. It comes with a 6-month warranty. The top is black with a crew neck, a close body fit and long sleeves with thumb holes at the cuffs. A finer mesh-textured panel covers the upper back, and contoured panels run down the sides, with a small CRAMSTER logo on the chest.
