Nice material. Like the built in undies. The zipper pocket is great for stashing a key when running. Colors go well with things.

Hey, there! So sorry to hear our shorts didn't provide you with the pocket size you like! We totally get it — those big-pocketed classics have a vibe all their own. We do offer other shorts with bigger pockets, like our UA Tech™ Play Up. I'll send you an email so we can get you the right gear.
PLEASE BRING BACK THE ORIGINAL ONES

I like the looser, comfortable fit and that this has a zipped pocket, but I wish it were bigger. It can fit a single key.
