Customer Reviews Smartwool Merino 250 Base Layer Bottoms

I bought these for winter runs. They run a bit big and fall down quite a bit, but are still a quality product

Soft, cozy, and warm. The elbows bag and loose shape after each wear.

I thought this would be pants but they look like underwear. I decided to keep them to wear under pants when it's very cold. They are comfortable as fit well.

Due to nerve damage from a car wreck I wear Smartwool quite a bit even in the summer. These summer nylon socks are great for boots or dress heels when wearing my pants!

I really like their solid wool baselayer fabric, so I purchased one of the prints while it was on sale, but the fabric is not as soft and comfortable as the solid versions. The back rise/waistband also dips a lot, I have a fuller butt, so sometimes I get a little dipping on the back rise, but this was extreme, they are clearly designed for someone with no butt. But this also makes them not the most comfortable or snowboarding or other activities where I'm bending over. I also wish they offered different inseam lengths, I'm short and 25" is full length for me, I don't need that extra 3" to bunch up inside of my boots. Unfortunately I haven't been able to find another brand with as great of fabric as Smartwool, so I still wear these for the warmth and softness, but I deducted 2 stars for the fit and length.

Soft, cozy, good if its not too cold. I would have liked it more but it falls down even though it fits. I would have liked a higher waist that protects my lower back more. Also would have liked a heavier weight.

I have many smartwool items and usually love them. The fit of these is off. There does not seem to be enough room in the butt which makes the waist line drop as soon as you do any actual movement. If it had a higher waistband or different fit in the butt these would be better

I purchased these for my upcoming backpacking trip since I'm a HUGE Smartwool fan (socks). Looking at the measurements and some comments on sizing I decided to size up, which now I'm conflicted about. The waistband feels like it sits weird (especially from the back) and the center crotch seam lowkey digs gnarly when I pull them up. It's not a very flexible seam so I don't even know if the M would've been comfortable. Either way, it feels like a woman didn't design these. Lots of bunching around my inner thighs. I love this brand so much and aside from the fit, the leggings are warm and feel great but like if the fit sucks, I'm not going to wear them comfortably. I paid a lot for leggings that don't fit me the way I'd like. Maybe I'll opt for the M. I really want these to work. I recommend Smartwool products all the time, but these leggings just fit so weird.

These are very warm, but they don't last. I've worn them a total of about 12 days, I was not hard on them, I washed according to the instructions, and yet there are holes all throughout them. The first hole, by the ankle, came on day three of wearing. There's now a few holes in the outside of one thigh, and several in the back, above my butt, as well as the crotch area. I love that these keep me warm while skiing, but I cannot pay 100+ dollars on a base layer pants that do not hold up with basic use.

I love the fabric (soft and cute pattern) but the rise is a bit short at the back for me, and the side seam on one leg twists around to the front.

Leg length is extremely long.

Wanted to love these - but seems to run short in the rise but really-really long in the legs. Will do the job - but much too Long for me (5'4"). Band sits below natural waist and doesn't quite cover the parts I want to keep warm.

Good fit but felt a little itchy.

These are super comfy but run large. I am true small in all of my pants but the small in these are noticeably loose on me.

Bought these as a base layer for colder weather. I would size up if you are bigger in the middle. Feels a little constricting. I am hoping they will loosen up with more wear. Otherwise, very soft and warm.

I bought this base layer to go snowboarding. It's super soft but it fits big and after wearing it for a bit the bottom part stretched and look sloppy. It looses its tight fit and shape.

I have a pair from 2017 and a pair from 2023. Both were gifted to me for Xmas. Obviously the older ones have sustained more wear, but they also keep shape better, have an entirely elastic wasitband, and have not had any holes. However the newer pit gets stretched out and falls down over time under my pants because they don't have an elastic waist. I also got a hole in the lower leg where the fabric was worn thin. These are still the best merino leggings I've had considering the warmth and price point, I just feel like the quality has decreased over time.

Fits great - plan to use as base layer under drysuit undergarment for polar diving. I think it'll work great.

Haven't worn this snowboarding yet, but it's so soft and washed well. I just wish it was a higher rise! For my long torso ladies/theydies, I don't think these are gonna stay on correctly when sitting, bending, or kneeling.

The pants are cute and the fabric is warm and cozy, but they are going back. Unfortunately camel toe is a thing :-(, and I would never want anyone to see that. Maybe an extra layer of fabric in that area or a different construction would help? I'm keeping the quarter zip top- love it!

I can't say how these perform because they were too large. They seem fine, but be wary of the sizing chart: I used it and my underlayer was definitely too large.

Nothing wrong with the actual leggings. Just not the color shown. They're actually more of a light blue vs the expected heathered white with light blue seams.

It came in very dirty from the factory. It's tends to be on the small size and not too starchy. I'll see how it'll hold after I wash it, hopfuly it wouldn't shrink.

These are my second pair. The first pair was perfect in every way, very comfortable and warm. But after washing the new pair they were extremely tight fitting. I'm hoping they will stretch out more with use.

For reference, I am 5' 6" and weigh 110 lbs. The medium was the right size. The small may be ok if you don't mind really tight pants that constrict your tummy. I prefer comfort over sexy so M would be my preference. However, I ended up returning these because it was quite clear, after trying them on for a few minutes, that I am allergic to wool. There were very itchy for me. Your experience may differ.
