A stretchy, smooth-faced technical layer for everyday activities the Patagonia R1 Daily Men's Zip-Neck is made from a soft 94% recycled polyester fabric. This feels like traditional fleece next to the skin, is, of course, wicking and quick to dry, with a brushed fleece interior that traps warmth. Built to keep you comfortable in the cold this is an alternative to a conventional baselayer for men looking for more from their core wardrobe. HeiQ® Pure odor control, a half zip for venting, and Capilene® Cool Lightweight fabric in the high-sweat zones along the collar and back of the neck for additional next-to-skin comfort and wicking this is a piece designed for the everyday feats, and the high energy, adrenalin pumping, adventures. With shoulder seams set for pack comfort and all the stretch for movement, there’s no mountain you can’t climb.. or trail you won’t want to ski.
