Inconsistent sizing
I have loved these shorts in years past so I bought another pair this season but the sizing is different and the shorts don't fit, despite claiming to be the same size. I'm incredibly disappointed and I wish that OR would at least let its long-term customers know if there is going to be a sizing change in the same model of shorts from year to year.
awesome
I wore these on a 4 day thru hike. I was going with minimal gear and these were the only shorts (or bottoms for that matter) I brought. They were great while hiking, I slept comfortably in them, and they were drenched with sweat everyday. They dried quickly and surprisingly didn't smell bad at all at the end of the trip. I got a size small, I am 5'4" and 125lbs. They were a little big but I was able to tie them tight enough. I am ordering a second pair because I really liked them, but I'm going with an XS this time.
Great all around shorts!
Love to wear these shorts on the trail or around the house. The colour is fun and bright, love the draw string waist, pockets and they are the perfect length.
Small shorts
(This review was collected as part of a promotion.) These shorts run small and I found they rode up in the front. I ended up wearing them mostly with swimwear. Probably won't wear them hiking because they're so short. I'd order them a size up from normal.
Absolutely Amazing Shorts!!!
[This review was collected as part of a promotion.] OR does it again. Stretchy, durable, moves with you, & doesn't ride up. Was hiking and sliding up and around on boulders with not a fre or tear.
Great pair of shorts!
[This review was collected as part of a promotion.] These shorts are fantastic for any outdoor activity. The material is flexible and moves easily with your body.
Exactly what I was looking for!
Perfect fit. Lightweight and super comfy. I'll be getting more colours!
