Comfortable and breathable!

I love these shorts. The only thing is that I think they run slightly smaller than I thought they would be. Still fit, though!

No Stretch AT ALL

I normally wear an XS and went with that this time as well. The shorts look nice but I couldn't get them over by hips very easily. Once they were on, they didn't look too small but there was absolutely no stretch in the waistband. Sizing up would have made them easier to get on but then they would've looked pretty baggy. Underwear lines are also very visible as there is no built-in underwear. Wouldn't repurchase.

Astro Shorts

[This review was collected as part of a promotion.] These shorts appear to be as described. They're super comfy for hiking, other physical activities and as leisure wear. I will be buying another pair!

Zero stretch in waist

If there's zero stretch in a waistline it needs a zipper, which this does not have. It was nearly impossible to get these over my hips.. I'm well within the size medium measurements according to the size chart. Once past the hips they feel good, but I'm not going to make myself struggle every time and maybe rip them.. I heard a few threads snapping when pulling them back off... these might work if you have narrow hips in comparison to the rest of your measurements, otherwise no. I don't know why I didn't heed the other reviews saying the same thing about the waist..

Ridiculous Shorts

As others have said (which I should have heeded) the waist is tiny with no give. Couldn't get them over thighs. Followed suggested sizing, and still had this issue. Wouldn't recommend these to anyone, unless you're very vertically uniform.

I'm wearing them now!

These felt great the moment i put them on. they are a bit snug getting over the bum as others have mentioned, but then they sit perfect on my hips. they're just the lightweight material i wanted and felt awesome on an impromptu run as well.

not enough stretch in the waist

I love the idea of these shorts, and once i managed to get them on they fit fine. However, it was a serious struggle to get them up over my thighs and butt (which are not tiny but also not huge!). Given how roomy the leg of the short is it was not a sizing issue. Not worth the struggle to take them on and off, so unfortunately i am returning them. For reference- I ordered a small, which is my usual size for active wear (5'8" 125lbs, pant size 27/4). If these shorts are redesigned to have a stretchy waist i will definitely re-order!

squeeze to get it on but once its on, the fit is great!

I really love these shorts. as the description states they are a tighter fit in the waist. I am curvy with a small waist and it is a struggle to get them over my butt, but once they are on, they actually stay up at my waist and look so nice. they also have a built in drawstring but i think this is the first pair of shorts ive owned i dont even need it. Thanks OR!

Waistband fits small

I like the shorts, they're light and have great pockets. However, the sizing is a bit weird. Definitely size up if you want to be able to get them on. I have quite a few OR items and ordered my usual size small. They fit once they were on, but the waistband is small and not very stretchy, so they were very awkward to pull on and off. I ended up returning them and getting medium ones.
