Rated 4 out of 5 by from Nice-looking shorts Very nice-looking shorts, but too small. I usually wear a 32-34 waist in shorts and pants. However, the 34 in these shorts is too small.

Rated 2 out of 5 by from Great shorts but lacking in design I bought these shorts because I needed something comfortable made with a stretchy material. The shorts were great but stretched a bit too much and stayed way too loose. One thing that would have really been nice with these shorts and that should be included on all biking shorts is a draw string waist band. Once these shorts got stretched out there was no way to tighten them back up.

Rated 2 out of 5 by from Nice design but durability is questionable Bought these less than two months ago, and I've been wearing them mostly as casual shorts. They're showing signs of wear (fabric seems to scuff and wear thin) without really using them as anything other than daily shorts. For the price, I'd expect a little more quality and durability. These will likely end up as yard work shorts.

Rated 5 out of 5 by from Great fitting and very functional shorts I never write reviews, but I like these shorts enough to make an exception. These shorts are great for commuting by bike and still look good in a casual setting. Fit is accurate, material is durable and has some stretch, pockets are deep, and the product labeling is subdued. Nice job on these, REI!

These shorts don't appear to have any belt loops. Is there any way to adjust the fit around the waist?

​These shorts do not have a waist adjustment.
