ExOfficio Sol Cool Boxer Brief

Just what you never knew you needed: rocks in your underwear. The Sol Cool’s defining feature is nylon fibers that have been infused with crushed jade particles, which resist heat and wick moisture. These boxers dry quickly and are perfect for hotter climes, or whenever you’re working up a sweat. “It felt like I was catching a beautiful alpine crosswind instead of sweltering in oppressive humidity,” said our tester after a multi-week trip through Australia. The nylon/cotton/spandex blend remains comfortable over multiple days on the trail, and the briefs retain their shape without being constrictive. Bonus: An antimicrobial treatment fights odor.
