Craft Sportswear Men's Active Extreme Long Sleeve Base Layer Lightweight Fitness Shirt: cooling/sport/bike/ski/run/sun/protection/top, Multi-Color, 2X-Large

Craft Be Active Extreme is made of a thin, lightweight and extremely elastic fabric that is channel stitched with two high-tech polyester fibers. A hexa-channeled fiber against the skin enhances moisture transport, which cools the body down. On the outside, a hollow fiber offers insulation as well as transport of moisture to the next layer. CoolMax Extreme fabric keeps smell and odor away.
