Hazel ★★★★★ Sep 11, 2026

Wore these straight out of the box on a bouldering session and the twill held up great against the rough granite. The heavier organic cotton blend doesn't stretch out or sag after a full day of climbing, and they still look decent enough for grabbing coffee after.

The fabric on these is noticeably heavier than most shorts I’ve tried, yet they don’t feel stiff at all. I’ve worn them on a few bouldering sessions and then out to lunch without changing, and they held up great.

These are my new go-to shorts for gym sessions and grabbing coffee after. The organic cotton twill is heavy enough that they don’t feel flimsy on the wall, yet they still breathe fine on a warm walk home.
