Take control of your inner thermostat with this warm, quick-wicking zip-neck, made with our new Capilene® 3 Midweight fabric to provide excellent insulation and next-to-skin comfort. The most versatile and fastest wicking of our performance baselayers, its new fabric offers even better stretch, durability, wicking and breathability, and has faster dry times. Brushed on the inside for warmth, it's soft and compressible, and the smooth jersey exterior glides smoothly under layers. The low-bulk zip-neck makes for easy venting. Details include raglan sleeves and underarm panels for unlimited mobility and offset shoulder seams to eliminate pack-strap chafe. Made with Polartec® Power Dry® 5.4-oz polyester (65% recycled) double knit with Gladiodor® odor control for the garment. Recyclable through the Common Threads Recycling Program.
