REI Co-op  Flash Pants - Women's

Wore these pants on cool- & warm-weather hikes carrying a 25L pack, and loved everything except the dorky hiker style. Con: they’re baggy and not cute, so if you’re out to impress squirrels these aren't the pants for you. The extra fabric may be annoying to some. However… Pros: very lightweight, no “swishing” noise from the wider legs, quick drying (thanks in part to the bagginess), very comfortable waistband including under a heavy pack, 3 deep pockets, breathable, and non restrictive for hiking or even climbing. Comfortable both on their own and with a base layer underneath for colder days. Will be wearing them backpacking next month!

Very breezy lightweight pants , soft ,stretchy and durable Nylon+Spandex combo. Quick drying but soft material which is hard to find combination. One zipper pocket on right thigh , big enough for iphone 15 ProMax. Two outside pockets with a small inner pocket inside one of them). Tie front drawstrings at waist, cinch waist for ankle so you can cinch the ankle bottoms and tuck it in to socks if hiking in mountains with fleas. Crotch and inner thigh area has vented material for airflow. Came out of wash with out any shrinkage . Good pair of outdoor pants from REI. Please see photos.

These pants are so comfortable that I end up lounging in them around the house after hiking. I got a size XS but typically wear a size Small. I think the Small would fit my waist better, but the waist band is stretchy enough that I can get away with the smaller size. The pockets are a good size and my phone easily fits in the zippered side pocket for secure storage or in the main pockets. The right pocket has an internal, more secure compartment for storing smaller items like keys. This is helpful since the main pockets are pretty loose. The length of the pants is perfect and the drawstrings around the ankles are convenient if you prefer them higher or when hiking with boots. The relaxed fit along the legs feels good when hiking and moving at faster paces. I've used them on multiple hikes in PNW winter weather. They are super lightweight and breathable, yet warm enough that I didn't need another layer of pants when the temperature was in the mid-40's. I even wore them in the upper 30's but I would have preferred leggings underneath. These will be very versatile since they are so light and easily packable. I will pack them in my running vest as a backup layer for mountain runs and use them for hiking year round since the UPF rating makes them convenient for summer adventures.

The sizing of these pants are odd, as the waist has a traditional fit, but the pant legs are extremely baggy. The material is lightweight, very comfortable and soft, similar to a scrub-style pant. They have movement and stretch, but are very thin, so I do have concerns about long term durability. The side pockets are nice and big (can easily fit a phone), except there are no back pockets (which is a pet peeve of mine). I’m assuming REI intends for these pants to be a more casual option? Unfortunately, I can’t see myself wearing these in public, and they would not be my first choice for on trail. It’s a miss from me.

Excellent range of movement. Lightweight, quick-drying fabric. I can see these becoming a backpacking staple in warm and temperature climates. Unforunately it's cold and snowy in AK right now and I have not been able to try them on the trails. Looking forward to taking these on summer adventures!
