If the body cools down, the muscles do not receive a sufficient blood supply. As a result, accidents and deterioration in performance can occur. The materials used for temperature control are highly wicking on the inside, offer ideal insulation and are extremely soft to the touch. A rapid escape of perspiration prevents the body from cooling down due to evaporation and the fabric from sticking to the skin. In this way, you can keep your body warmer and drier Buy Gore Bike Wear Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
