Versatility is the name of the game with the Patagonia Capilene Midweight Zip-Neck Top. For the winter athlete who wants to wear the same thing for running, climbing, skiing, and hiking, this 1/2-zip baselayer is made from hollow-core yarns and a diamond-grid pattern next to skin helps to trap warm air and wick moisture for all-day comfort. Patagonia treated this top with odor-fighting HeiQ Fresh Tech for fresh comfort on full or multi-day adventures. Raglan sleeves and a flatlock construction minimize chafing, while the underarm gusset keeps your range of motion uninhibited. When you're layering on extra cold mornings, the elastic thumb loops help secure the sleeves so you can stay nice and comfortable throughout your day.
