This is an interesting pair of shorts. The welded seams and material remind me of a wet suit but it's clearly not.
Pros - Very comfy, they feel good when wearing them. Very light weight as well. Size seems to run true for me. I'm 5'10" 175lbs and I'm wearing a medium. Great for wearing as casual wear.
Cons - I've run in them a couple of times and I'm not real thrilled with them for that. I think it's because of the leg length. I like my running shorts to be above the knee and these are not. Not much in the way of storage capacity for a wallet or keys, pockets are small.
Bottom line? I like them and will wear them as casual shorts. For running? No. I'll probably get another pair or two.
