Fantastic shorts for on and off the bike
The shorts fit true to size, the zipper pockets are fantastic, and they are much more durable than the original AT shorts. Mine look like they’re still brand new after a few spills on my local trails.

Bombproof shorts
Comfy, stretchy, super durable - I didn’t expect to like them this much. Only wish there were a few more colors!

Durable, affordable, comfy
Just wrapped up a 5-day bikepacking trip in these shorts. Solid/trim fit (follow the size chart), durable in the crotch & seat (may hours in the saddle and sitting on rocks/ground), and they don't break the bank to get in them.

AT plus Shorts
Love the fit. The only improvement that would be nice is a cell phone pocket that’s more on the side of the leg. A phone in the front pocket isn’t real comfortable

Almost perfect
Great fit, super comfy, seem to hold up well. Could do without the silly zippered pockets, though
