Rated 5 out of 5 by from Perfect Fit And Great Warmth Let me start by saying I'm 6'0", weigh 115lbs, and I have a 24" waist. So when I say it's hard to find long underwear that fits, I really mean it. I found these at REI on a clearance rack, and immediately fell in love as soon as I tried them on. I'm autistic, so I often have trouble with wool-based garments, but the texture of the material is soft and comfortable. These long underwear are light, but really nice and warm. I can hardly tell I'm wearing them. Plus, they're nice and fitted, so they trap heat really well. If you're looking for a pair of base layer pants, I highly recommend these.

Rated 5 out of 5 by from Great lightweight baselayer Fits me like a glove and definitely works to keep me warm. I am 5'5" and weigh about 118lb. With the elastic band covering my belly button, these pants stretch all the way down past my ankles but don't bunch up at the ankles. In other words, a perfect fit. The elastic band is not too tight and not too loose so quite comfortable. I intented to sleep in these but may opt to just wear them under pants when I go out because I like waistbands a lot looser for bedtimes.

Rated 5 out of 5 by from perfect fit and thickness Size is perfect as on size chart and they feel great. Not too thick and not too thin....juuuuuust right! I need something to keep me warm in TX, not in the arctic, and these are perfect.

Rated 5 out of 5 by from Comfortable light warmth Excellent base layer. I wore it under two additional mid-weight layers while winter camping and doing other outdoor activities for several days in a row in subzero temps. It felt like a second skin: hugged my body from waistband to ankle, gave where needed, and was relaxed enough to sleep in. Smelled fresh after wearing several days in a row and washed up easily. The petite fits me perfectly--I'm 5'4" and 140 lbs.

Would these be appropriate and comfortable to wear as leggings under a dress with boots or sneakers?

Asked by: rfergu
These are comfortable to wear under a dress. There are seams down the side which traditional leggings do not show; your comfort level with wearing these may be a matter of personal preference.

How are these to be washed? I don't see an instruction tag attached to the clothing.

Asked by: Lisa
REIservice · 2 months ago   ​We recommend washing this shirt in warm water on the gentle cycle with mild detergent and line dry. This is REIservicw reply under the top for this item. My guess is the recommendation should be same for bottoms.
