Rated 5 out of 5 by from comfortable fit and nice material These caught my eye and of all the pants I've tried at REI, these are by far the best fit and fabric. Most of the pants fabric seems too thin or stretchy, but this was just right. I'll admit, my primary use is casual / travel vs hiking. These are comfortable and stretchy enough to add a base layer (or base + mid). Mid rise gave me enough coverage without being tight on the waist, and there is a drawstring in the waistband as well. I took a size 6 pet, and am 5 ft 120 lb, 34 waist and 37 hip. Hope this helps and they come out with more colors, I've already bought a second pair

Rated 5 out of 5 by from Tough, comfortable, warm & quick to dry... Just bought these and tested them on a tough Arctic Alaska hike right away. Scrambled up and down steep slopes, through willow thickets, across a calf-deep snowmelt stream, wore them in wind and rain and stayed dry, warm & comfortable. I never felt constricted; they also never felt loose. These may be the best pants I've ever bought. Going to surprise my partner with a pair of the men's.

Rated 3 out of 5 by from Sizing runs too big I am disappointed in the sizing of these pants. I am a consistent 2P across brands of clothing, but these pants were way too big. I had to double-check the tag because I didn't believe that these were a size 2P. They would not have stayed up with a backpack on. Very bummed to learn that REI is not offering these in a smaller size because other reviewers make them sound so great, but if you are typically a size 2, these are unlikely to work for you. I am 5'2" and 117 lbs.

Rated 1 out of 5 by from Nix the plastic buttons Unfortunately I bought this 1 year and 3 days ago so am not eligible for refund. The plastic buttons were getting more difficult to snap, but these pants were great, so I kept them. Yesterday, my husband had difficulty snapping them on for me -- I tried any number of unsuccesful way to snap them. Once on, I could not get the pants off by myself and had to ask for assistance, again. Didn't want to imagine what would happen if I had to go. This morning, I checked my purchase records -- 3 days past 1 year. I'm stuck with expensive pants which I can't use -- it's great and a perfect fit, durable and comfortable. REI needs to replace the fasteners. If you are finding it difficult to snap, return before your 1 year is up.

Rated 5 out of 5 by from Great Pants! I can move around in this pants! My favor pair of pants. I am 5' short. The petite length is still an inch longer, but it is my height problem. The material is so soft and stretchable. I don't mind to pay full price for a great pair of pants after returned all purchase from online and tried more than 10 pair of pants at the store.

Rated 5 out of 5 by from Great purchase Wow I'm impressed with these pants. Super comfortable and light. Great fit and durability. I will recommend and also consider these in another color.

Rated 5 out of 5 by from Beautiful pants, I love it This pair of pants is stylish (sometimes I wear to office), comfortable and practical. Many compliments I had received about it. It is stretchable, wind and water resistance, these features work well for my outdoor activities. I look forward to other colors to become available in near future for selection. Will love to have more pairs.

Rated 1 out of 5 by from Not Worth It After 2 washes (cold water, hang dry), the water resistance seems to be going. Went for a 4-mile hike while it was sprinkling today, and about a mile in my thighs started getting wet. After 3 miles I was soaked. They're also not very flattering on me; I'm 5' 2", size 10 in these, and the legs are a lot wider than they look on the model. Not practical and not stylish = not worth it.

I already have the REI Sahara Roll-up pants and love them but I'm looking for something a little heavier to hike the Tour du Mont Blanc in August. Are these heavier or comparable to the Sahara-style pant?

Asked by: haleynoelle
​These pants are slightly heavier than the Sahara Roll-up pants.

I just bought a pair of these pants and I like them very much, but the waistband is a bit too big and does not seem to have a drawstring (as mentioned by another reviewer). Or is it hidden somewhere?

Asked by: Runjenn
These pants do not have a drawstring on the waistband.

I am confused by your sizing chart. I would like to buy the (petites) Medium but not sure if that is petite 12 or petite 14?

Asked by: clay362
You can order your specific size of 12 or 14 petite respectively. Our size chart is a generic reference that groups two sizes representing a size range.
