Silk Weight Polartec Power Dry® fabric. This high tech fabric wicks moisture better and dries faster than any material we've seen. It is a very light material with a smooth, silky feel. Two distinct fibers are used to create two unique surfaces (a "bi-component" knit). The inner face uses normal polyester fibers to pick up sweat from the skin, while the outside face is knit from smaller microfiber polyester, which spread sweat out over a wide surface for rapid evaporation. This patented construction works like a dream - the fabric readily absorbs sweat from your skin, but still feels dry because moisture is immediately passed through to the outer surface, where it is free to evaporate or pass into your next layer. Provides a Sun Protection Factor (SPF) of 20+. Wash cold and hang dry to avoid shrinkage. 100% Polyester.
