The 3D pouch actually keeps everything in place on long runs, which I didn't expect from a boxer brief. Waistband is thicker than my old pairs and doesn't roll down. Wore them three days straight in Whistler and no chafing.

These are snugger than my usual boxers, which I actually like for hiking since nothing shifts around. The 3D pouch does its job, and the limited edition print is a nice change from plain black.

The thicker waistband really holds its shape all day without digging in, and the 3D pouch keeps everything comfortably in place during my long bike rides. The Whistler artist’s design gets compliments every time I change at the gym.
