I need more pairs

I've used it several times
Size Bought:
6' 3"

I’ve lounged, worked, and hit skatepark on 115°F day and this underwear is comfortable everywhere. They are super soft and lightweight without feeling flimsy. I want a pair in every color.

These... are not great.

I've used it several times
Size Bought:
6' 1"

I was very excited about these, as I have some older (different model that they don't make anymore) boxer briefs from Patagonia that are great, and the soft fabric and fun patterns of these impressed when shopping and feeling them after arrival. At first they seemed great: comfy, stretchy, good construction... but after a few hours of wearing them I noticed they continually "ride up" on my legs, and I have to pull them back down - I'm sure not everyone will have this problem, but it's very annoying, and I don't struggle with this issue on SAXX or OR underwear (my go too's), so something about the cut or fabric of these isn't working that well for my (large thigh-ed, hairy) body/leg type. To add a real punch to it, after wearing them occasionally for a few weeks (in a vane hope that the ride up issue might go away, since I didn't feel like I could in good conscious return a pair of underwear after wearing them) the fabric has already started to pill. Not impressed by Patagonia on this one - I'd say steer clear until they change the fabric and maybe the cut of these, unless you know they work for you.
