Wish I’d found these sooner—the cotton feels genuinely soft against the skin, not that stiff fabric you get with most trunks. The 4.5” length sits right between a short and a brief, so they work for both lounging and the gym without riding up. Already ordered another pack.

The 4.5" inseam hits that perfect sweet spot between a short and a brief, and the cotton somehow stays breathable even after a full day of wear. I ordered these for lounging and ended up wearing them to the gym too.

The cotton feels genuinely softer than your average pack, and the 4.5” length sits right between a short and a brief without riding up. I wore them for a full workday and forgot I had them on.
