North Peak Lightweight Inner Hollow Medium Men's Tights, Warm, Moisture-wicking, Quick-drying, Fiber, NP-8075 Black,

Lightweight and flexible, it uses hollow fibers that are highly heat-retaining, absorbent, and quick-drying. Capillary action allows for both moisture absorption and quick drying. It absorbs sweat and releases it to the outside, so you can always feel dry. The inside of the yarn is hollow, making it lighter and more comfortable than it looks. Air is trapped in the hollow space inside the yarn, providing heat retention.
