The most versatile and fastest wicking of Patagonia's 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. Details include a rib-knit collar, raglan sleeves with underarm panels for unlimited mobility and a tuckable hem. 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.
