It seems that stretchy is all the rage in board shorts. If that is what you want, then these aren't your shorts. These remind me of old school "B-well Beach Britches" type shorts. They are made of heavy nylon, no liners, a couple of pockets and nice and loose in the legs. I have cycle and do cross-fit and have large thighs, so some of the shorts are too tight for me. The fit in the waist is true to size. I like 'em so much I bought a pair in black too.  Nice rugged quality, I expect them to last for years to come, so long as I keep them in the salt water and away from the pool.
