The Men's Patagonia Capilene Midweight Bottom is a next-to-skin layer for cold weather days in the outdoors. Whether hiking, skiing, climbing, or other, the smooth, soft face makes it easy to layer and head out for some adventure. The fabric is treated with HeiQ Mint odor control to keep things fresh, while the diamond-grid pattern provides warmth, breathability, and moisture-wicking performance. The gusseted crotch is for comfort and unimpeded mobility with a functional fly and flatlock seams to minimize chafing and a stretch for added comfort and improved fit during movement.
