The Patagonia Women's Capilene® Midweight Crew Long Sleeve hits the sweet spot of weight, breathability and wicking. Wear it alone, or under layers to stay dry and comfortable during high-exertionactivities in cool-to-cold weather. Constructed with Polartec® Power Grid™ fabric, Capilene Midweight has a smooth face for easy layering and a brushed-back grid that aids in wicking as well as warmth. Solid-colored fabrics have 93% recycled-polyester content, heathers have 63% and both are treated with Polygiene® permanent odor control. Features include a rib-knit collar with internal neck tape for chafe-free comfort, full underarm gussets for unhindered shoulder mobility, elastic thumb loops to cover your hands, flatlock seams to minimize chafing, raglan shoulder seams and offset side seams that lie smoothly beneath pack straps, and a drop tail for additional coverage.
