This is your piece for early morning powder shots, spring bouldering sessions, summer alpine routes and late-fall trail runs. Patagonia's most versatile performance baselayer, soft and compressible Capilene 3 Midweight stretches, dries quickly, resists wear and provides excellent insulation and next-to-skin comfort. The fabric is brushed on the inside for warmth and has a smooth knit face that glides smoothly under layers. Details include a reversed self-fabric collar, tuckable drop-tail construction and thumb loops for secure hand coverage. Made of a 5.4-oz Polartec Power Dry 100% polyester double knit, with Polygiene permanent odor control. Fabric is bluesign approved.
