The 3D pouch actually keeps everything separated instead of sticking, which I didn't expect to notice so much. Fabric is thin enough to breathe during workouts but hasn't stretched out after a dozen washes.

Wore these on a 12-hour travel day and forgot I had them on, which never happens with my old trunks. The 3D pouch keeps everything separated without any shifting or chafing.

The 3D pouch is a game changer—everything stays put without that clingy feeling when you’re out of the water. I’ve worn these on long beach days and they’re just as comfortable after hours of swimming as they are dry.
