These are the first boxers I've owned where I actually forget I'm wearing them. The 3D pouch keeps everything separated and supported, which cut way down on the chafing I used to get on long runs. Ordering more.

I wore these for a full day of moving boxes and never had to adjust once. The separation from the pouch keeps things from sticking, which I didn't know I needed until now.

The 3D pouch really does its job—everything stays put without any shifting or bunching when I’m moving around all day. They’re the first boxer briefs I’ve worn where I genuinely forget I have them on.
