Patagonia W’s LW A/C Buttondown

Beat the heat in the Patagonia Lightweight A/C Buttondown, a long-sleeved shirt that somehow keeps you cool even when temps are climbing. The 95% organic cotton/5% hemp blend breathes like a dream and feels light enough that you'll forget you're wearing sleeves. Summer shirts don't need to be short-sleeved when they're built like this.
