Polartec Power Dry is a low bulk base layer insulator designed to keep athletes dry during strenuous activity by wicking moisture away from the body. This fabric is a two layer system, an inner layer designed to wick moisture and an outer layer designed to dry quickly.This fabric is highly breathable to aid in the movement of vapor. The tow layer system wicks moisture and vapor with the inner layer where is collects on a quick drying outer layer so the base layer stays at least 30% dryer than single layer wicking fabrics.
Overall you get a superior breathable wicking fabric that keeps your skin dry when you sweat. To top it all off, this stuff is machine washable
