This versatile crew provides warmth in the mountains or wicking on a trail run, along with superior breathability and the fastest dry time of all their Capilene® fabrics. Worn alone, it keeps you dry and cool during high-exertion activities in warm conditions. Worn under a shell when a chill wind blows, it wicks perspiration and helps to insulate. With a soft, self-fabric neckline, modified raglan sleeves for the full-range of motion and overlocked, offset seams to eliminate chafe. Made with 4-oz 100% polyester (54% recycled) with Gladiodor® odor control for the garment. Recyclable through the Common Threads Recycling Program.
