Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

I bought 5 more pairs this year in different colors

I love these. Keep me warm inside and out

Warm, not itchy, good fit

This is my first product from Smartwool. I bought a top and bottom together. I was very happy with how well they fit (true to size) and super surprised with how soft and warm the material is! I mean, it's merino wool, so it should be soft, but I've had other merino wool products that just aren't nearly as soft. I'm excited to have this for my next ski adventure!

The material is amazingly soft and comfortable, and warm without making me sweat on the slopes, hence the 4 stars. The waist is a bit big, and I am not a small waisted person. For me, they are mid to almost low rise, and I was worried that they would fall down during my day of snowboarding, but they stayed up, so that was good. I wish that they had TALL sizes. They are about 3 inches too short for me, which is covered by my socks, but not ideal. They would be more comfortable for us talls if they were higher (and slimmer) waist, and longer in the leg. I am 5'11", 170 lbs, athletic build, and got Large.

Great

Fit was fine but material quality has gone way down

Thin enough to go under jeans or pants. Kept me warm all day even in 20 degrees with 30 mph winds while hunting birds

Super soft and warm. Great blue color. Wore under pants while kayaking fjords in Iceland. I was never cold.

So far so good, I basically live in them.

These are thick enough to wear alone.

Definitely a great base layer but the arms are too long on both my roommate and I who ordered these together #sweepstakes

I always wear these not as a base layer, but instead like leggings over silk long underwear (1-2pr depending upon the weather) I have several pair from a variety of years. I think the sizing has changed slightly in that the Large size is a little longer and looser. Unfortunately, I also feel they have become a little thinner

I am 5'8", 150lbs and 62yo. I bought the large by viewing the sizing charts. So the bottoms are a little large but may shrink some after laundering. The warmth is amazing. The color is perfect. I was in a time crunch so couldn't try to exchange as the company so graciously provides w return labels. Well worth the $

I've used these for dog training, running and snowshoeing in windy, wet weather. I ordered my usual size and despite the yoga pant design felt they are cut too low and the waist too tight for where it hits. I returned them for one size larger which brings the waist up higher. The legs are loose but snug enough to fit under compression tights. If you're on the larger side of the size range, I'd consider ordering up.

We've had an unusually warm winter so I haven't been able to try this out, but I think they will keep me nice & warm. I'm looking forward to it.

kept me warm as a hiking base layer, but don't love to wear them without a lay over them. I also feel the waist band is slightly weird, it feels like it doesnt sit evenly, almost like it dips in the middle. material is not itchy.

I have worn them once. Wished I had the chance to try them on in a store to compare the medium and small, I might be an in between. They are warm and I am glad to have them.

This is my first purchase (outside of the gym) of "leggings". They are warm and fitted. But without the usual compression of most leggings. That may or may not appeal; it's fine with me. What's best is that they don't bag at the knees.

These are warm but feel a little bit itchy to me. I kept them because I tossed the tags and packaging.

I wear leggings around the house every day. I have some cotton ones with pockets for the summer, but when it's cold, I want merino. These leggings are a perfect fit, great fabric, but not useable for daily wear around the house because they DON'T HAVE POCKETS! I know they're a layering piece, but please make a pair with pockets! I looked at the moto tights, but people said they have too much polyester. I want something warm and soft. PLEASE MAKE A PAIR OF THESE WITH POCKETS!

I have previously purchased 30 bellow thermals and wanted to upgrade after they started to pill up and fall apart after a year or so of use. Overall these feel warm, fit smaller than expected and are a bit itchy. Would have expected more for the jump in price from my previous pair. I'm a size 8 short and should have bought a large instead of medium.

These leggings are comfortable and warm and seem thick and durable at the beginning of their life. About a year in they started to get runs and then numerous holes. They did get a lot of wear, around the house, town and trail, but I wish they had held up for longer than a year. I'm not interested in fast fashion and bought smart wool for the quality. I did recently buy another pair bc they are good leggings/base layer while they last. Hope this pair goes longer than the last!

I've had my 250 leggings for about a month. Overall, I love them and would buy them again. From my perspective, they're more utilitarian than anything else. Excellent for layering underneath a pair of hiking pants or jeans in cold weather. Very soft fabric - I did not expect that! I would categorize them more as women's long johns. Don't expect form fitting, booty flattering leggings. These are not those. The fit is perfection when you first put them on, but after a few hours, the fabric in the legs really loosens up. I wouldn't wear these leggings on a night out where I am trying to look cute, but will definitely use them every time I'm doing something outdoors in the cold weather. And, TBH, I do more of the latter anyway. So, if you're looking for a comfortable, warm, well made pair of ladies long-johns, I recommend the Merino 250. (Four stars because of the thin waistband. This could be improved.)

Its perfect i love it
