Fabric is thin and clingy

The fabric is not how it looks in the photos, it's thin and clingy and out lines the linings of the pockets and any dimples you may have in your skin. Waist is large while runs small through thighs and hips, fit like poorly made leggings and hold onto body odor despite use of laundry disinfectants/borax etc. Not even worth the sale price, definitely do not buy full price, you could do so much better with that money.

Great basic climbing pants!

This is great staple climbing pant option for those looking for a water-resistant (not waterproof!) and full length climbing pant. I got caught in the rain with these and they held up for about a minute before my legs got soaked through. Overall, slightly stretchy which is nice for climbing, and the regular length doesn't result in a cropped pant which I like as someone with longer legs. I bought this in a size 2 but it was too big for me; I use the inner drawstrings to tighten them all the way. I'm 5' 8" and 110 lbs.

Great Travel Pants

I wore these pants multiple days in a row while on a walking tour in Japan. They were super comfortable and fit well. Every few days I washed them and hung them to dry overnight. Great choice for the active traveler.

These are the greatest!

Wore these on my 2 week trip throughout Slovakia. These were the only pants I took and they washed out nicely and dried overnight. Wearing these, and taking only 1 extra shirt I was able to travel with only a bookbag! And so very comfy, too!

Comfortable and durable

I wear these for field work and they are comfortable and have held up well. I typically but a size 12 in pants but find the waist snug in OR products so I sized up and am glad I did.

Awesome waterproof pants

I've gone through a lot of outdoor/field pants, and these are my favorite so far. Today I submerged my legs in flowing water up to my knees for about half an hour, and the pants remained completely dry. I didn't buy these because of the waterproofness, however, these will definitively be my go-to pants for rainy/wet days. Other than that, they are very comfy and look nice. The only small downside I've found is that they seem to have stretched a bit after only a few days of use? I'm hoping they'll shrink in the wash.

Lightweight, good stretch but poor wear

The pants are comfy and lightweight. However after wearing them for about a dozen times they are showing a lot of wear. The threads have gotten fuzzy, and the fabric is no longer as smooth. They also seriously stretch out after about an hour of wear, almost to another size. Greatest concern is they will not last

Love the pants, with two flaws

Love these pants so much I bought them in two colors - the verde, which is gorgeous, and the orange. Two big flaws: first, they stretch out so. Much. I returned a size 4 initially because while they looked nice standing, it was hard to get things into the pockets and they cut into my thighs and waist in an uncomfortable/unflattering way when sitting and kneeling. The next size up fit great! until I wore them around for the first time. They stretched out so much they are now baggy and deeply unflattering, although the pockets are still too tight! Other more minor flaws - one of the back pockets is zippered, which feels like a waste. I'm not going to put anything in the back pocket like keys that I would want to zip up, because I'd sit on them. The other thing is that I really wish the OR logo was not printed on the leg. I think they'd look so much nicer without that. Nonetheless, if not for the unpredictable fit from first wear of the day to the end, I'd probably have 5 more pairs. The material is light but still seems durable and repels a very light rain.

Love the pants, hate the customer service

Other reviewers said that sizing runs small, so I ordered both a size 12 and 14. The size 12 fits great, and the pant is really nice for hiking. In fact, I've ordered another size 12. My problem is with Outdoor Research's customer support. I need an order number in order to return the size 14. I keep calling, but for over a week, no one has answered the phone (there's just a message saying to send an email). I sent an email, and it took four days for a response. Unfortunately I was given an order number that doesn't work. Now what? Wait another four days for an email? Why doesn't OR have people we can talk to??
