Customer Reviews Smartwool Merino 250 Base Layer Bottoms

These Smartwool base layer bottoms are perfect for camping and snowboarding! The 100% merino wool keeps me warm without overheating, wicks moisture, and resists odorsideal for long days on the mountain or chilly nights at camp. The fit is snug but flexible, making them super comfortable under snow pants or joggers. Whether I'm hitting the slopes or truck camping in the cold, these are a must-have. Highly recommend!

Fantastic base layer for spending many hours outside delivering packages on cold days.

Quality is good as usual for Smartwool. Shipping leaves a lot to be desired. It was supposed to be delivered 2/7 finally got it 2/14. Tracking wouldn't open at least half the time. Never on computer only on phone. Will look hard to buy some place else

Wonderful if working outside in the cold weather!

When it's 9 degrees outside wearing these under my jeans sure helps. I especially like that they don't pull the hair on my legs. I highly recommend this base layer or for just laying around home.

I got 2 pairs like 15 years ago and love them. The only wear is a couple of moth holes. I've worn them for everything from being outside all day doing commercial snow clearing, to hiking, to skiing. I finally got some more because I wanted to get another pair into my rotation when I'm on cold weather vacation when I don't have access to laundry.

I wear these on the slopes or just for chillin! So warm and comfy.

A good warm pair of thermals

Purchased for my husband to take on our trip to Iceland, along with the matching base layer top. Did not disappoint! My husband thought they fit perfectly and were cozy and comfy! Worked perfectly under his snow gear, and even just to lounge in! Will absolutely be ordering more!

Got these for my husband who skis. He texted me from Tahoe and said they are great and "even better than the other ones you got me." I got him a set a year or 2 ago. I used the sizing guide. Got him a medium even though he usually gets large boxer briefs. (He has enormous muscular thighs that impede his ability to wear certain clothes- lol) But he said these fit fine!

Warm enough for Montana winters without bulk so that it can be worn inside and for chores outside.

Great layer when it's cold. I work outside and these are great when it's winter time. Fit right and always keep me warm.

These thermals put all others to shame - Incredibly warm and comfortable, I've already ordered another pair!

Comfortable, warm, breathable. I was on fence about this purchase for a while but I'm glad I finally purchased them. Merino wool really is a game changer.

Perfect fit keeps me warm

Great base layer, well worth the investment to stay nice and warm. Definitely recommend. Works better than any other base layers I've tried.

Used on Utah ski trip in 5-10 degree (F) weather, kept my feet warm and comfortable.

Perfect! Works great tucked into socks and work boots over top.

These are the perfect weight, warm enough when it's cold, yet not too warm inside. Having a natural material on your skin makes all the difference.

I have a lot of synthetic long John's, but these wool ones are far superior. They just keep you warmer.

These are a huge upgrade from my previous non-merino wool base layers. I wanted to get away from the plastic fibers and these were better than I expected. The Medium sized fit my 32inch inseam perfect and the feel is so much better than my previous base layers!

Love the weight and warmth. I will keep supporting Smartwool.

My legs were cold, but now they are not. I wear them with normal boxer shorts underneath still, since they last longer in between washes that way. But without boxers they are also very comfortable. Sometimes I forget I'm wearing "underwear" and step outside to get the mail wearing just these and a shirt.

I bought this for my son who works outside in construction & he really likes them.

Amazing product. Keeps you warm without as many bulky outer layers
