The fabric feels impressively light for something that still holds up against brush, and the stretch moves with you on steep climbs. I've worn them three days straight on a prairie trip and they breathe well enough that I forgot I had them on.
The fit is spot-on even after a full day of scrambling through creeks, and the lightweight fabric breathes way better than my old pair. Pockets hold a phone securely without flopping around on the move. Wore them from dawn till dusk and never once felt the need to change.
Took these into the backcountry for a weekend and the lightweight fabric moved with me through brush and creek crossings without any drag or stiffness. They dried off quick after a splash, which made the hike back a lot more comfortable.
