We fell in love with the Patagonia Capilene Cool Lightweight Short-Sleeve Shirt after a summer trip through Moab sent temperatures into the triple digits. Its recycled fabric wicks moisture after working up a sweat on the trail and dries quickly to prevent you from looking like a sweaty soggy mess. Best of all the built-in odor protection fends off unwanted funk so you can rock this tee for a few days before your friend begs you to wash it.
