The fit is true to size and I like the stretch. The fabric is soft to the skin and does NOT irritate my legs even with sand. They also are very durable and haven't had any problems with them.

Husband is a repeat buyer of these shorts - loves the fit and stretch

These shorts are great not only for surfing or water sports, but they are also great for working out, riding your bike around town, etc. The material is very comfortable and allows for some flexibility. I have a size 32" waist, but I purchased the 34" to accommodate for my larger quads/glutes.

These are great boardshorts. The stretch makes them really comfortable. They are cut nicely so that I don't look like a teenager in oversize shorts but also not like I stepped out of the Land's End Catalog. My only complaint is that the fly is a little weird in that it only has one button and doesn't open very far. Otherwise perfect.

Great pair of board shorts. The stretch fabric is great for mobility. They are cut small, I had to return and size up.

I like this board short but had to exchange them for a size up. I wear a 32 in most shorts but had to get a 33 in these. The stretch fabric makes them a lot more comfortable than the non-stretch version of this short.

I bought a pair of these a few months ago from backcountry. At first, I though they were great- they fit well (although Patagonia sizing is all over the place: I got these in a 34, and they are pretty loose around my hips. I got two other pairs of the normal , not-stretch shorts in the same size and they would barely pull over my thighs).
I used them most weekends for a range of water-based activities from water-skiing/wakeboarding to kite surfing, or just chilling in the pool. They looked great ... then the stitching around the hem started to come undone, before the seat blew out when I was kite surfing.
I get that gear like this can't be bomb-proof but I am really disappointed that these failed so quickly. These were big on me, so it's not even as though I was putting the seams under a lot of load. I love the Patagonia branding, functionality and styling, but this is not what the brand- or the pricing- stands for.

I guess the search goes on for the perfect board short. This certainly isn't it.
