Outdoor Research Echo Boxer Brief - Men's

At 2 oz with AirVent™ moisture management and ActiveFresh™ odor control, the Outdoor Research Echo Boxer Brief is the kind of base layer you don't think about, which is exactly the point. Flat-seam construction keeps chafing out of the equation on long days out, and they dry fast enough to double as a swim brief when the trail passes a lake too good to ignore.
