Complete fail
Waistband is incredibly stiff & digs/cuts in. Plus it’s so thick that it reminds me of cheap 80’s gym shorts??! OR was definitely overzealous in adding length to the belt too - because - if one had a waist that was so large it warranted using that much belt then they definitely wouldn’t be able to squeeze their big waist into this tight waistband. The excess “belt” just hangs like a limp noodle. Not a good look. Comparing to previous year’s model, it’s a complete fail. The material is slightly thinner, more roomy around the hips & leg holes, but the waist band is wider, tighter, & more rigid (as I mentioned above). Does anyone even try these things on? Who is designing these?!
Very comfortable
My wife enjoyed these shorts. They fit very comfortable, breathable, and even have functioning pockets. The built in belt was useful.

Belt is too short to get shorts over butt
These would be great except the built in belt is too short to get over my butt without losing it, it disappears into the waist band and then I have to fish it out for 10 min. Great shorts if you have no butt. It’s an easy fix—make the built in belt longer, but for some reason both times I’ve bought these (2nd time hoping it was fixed) I have the same issue.
favorite shorts
I practically live in these shorts during the warm months! The material is comfortable, the colors are fun, and they don’t restrict my movement. I have an athletic build and often struggle to find casual shorts that don’t feel too tight on my thighs—but that’s not an issue with these. I wear them for everything—gardening, running, biking, hiking, and more.
Great shorts for just about everything!
I love these shorts. The fit is a bit more relaxed which is good for people like me with athletic thighs. Great for hiking, water sports and every day wear. People complained about the long belt, but I think that is just the style these days! I am going to buy again in another color!
