Max lifts, peak bags, negative splits-the ExOfficio Give-N-Go Sport 2. 0 9in Boxer Brief keeps us cool, supported, and mobile through our grittiest pursuits. The 4-way stretch gives us a snug fit and follows our every move, while the smooth flatlock seams and mid-thigh inseam prevent chafe from slowing us down. As the sweat flows, the treated, ultralight mesh staves off the stink and quickly moves moisture away for the only bit of comfort we'll feel in our training sessions.
