Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

I am 5'3 and 125lb and these fit perfectly

Fit is great, true to size. Comfortable, warm and not itchy.

Bought these for my girlfriend. She loves how comfortable they are. I love how sexy she looks in them.

So soft and cozy! Fit is amazing. Girlfriend loves them, even though black and grey aren't her go to colors. Make more exciting prints and colors Smartwool!

I live in these base layers around the house and also use them as designed out on the slopes or when hiking in the snow. This particular pair has a great color to match the hooded base layer I purchased, as well, and I like the combo together.

It feels great, just like the older one I bought years ago!

Fits according to size guide, washed it and only minimal shrinkage after using the dryer (next time I will air dry). Comfortable in the legs and waistband stays up well. Good for a layer underneath jeans or other pants.

Great to get a new pair - always a favorite.

These are my new favorite base layer bottoms. They are on the thicker side of active base layers but they are so comfortable and have been great for skiing and days out romping around in the snow!

Feels true to size and not too thin, compared to other baselayers.

Cozy warm and lightweight.

I bought this as Christmas gift for my girlfriend. She really liked it. Excellent quality of the material. Sizing is perfect. Highly recommended !

I've had my original pair for almost 10 years! They've lasted and held up so well, I will continue to wear them, but am excited for some new colors.

Super comfortable and a great layer of added warmth.

Great base layer for skiing and hiking. Warm and soft. Keeps me dry!

I purchased these for a winter holiday. They arrived shortly after I ordered, so I was able to try them while lounging at home. They are completely cozy and not too hot in our tropical climate. Now I am on holiday in Northern Japan where the snow is deep, the wind chill is well below freezing and these leggings keep me comfortable and warm. I am so thankful to have these versatile and comfortable leggings!

Always the warmest. My daughter asks for a pair of these and socks for every Christmas

I got these for my girlfriend and it completely changed her experience on the mountain

Purchased for myself. I work on a ski mountain and spend a lot of time inside and outside. I love the comfort, the style & warmth. My only problem is I want more!

Great fit. Warm and comfy?

Got these for my MIL and they are perfect!

Great color and soft material.

I use this as a ski/snowboard baselayer. Functions perfectly, great fit and based on past experience with Smartwool, holds up well with heavy use.

No such thing as bad weather.unless you forget your Smartwool base layers! Just the right amount of thickness to wear under your clothes, leggings, ski pants, or by themselves in a sleeping bag! Fits true to size, wears exceptionally well- just remember air drying is best!

I needed a very warm base layer for an upcoming trip and since I've been pleased with Smartwool socks, I decided to try the merino base layers even though I'm exceedingly sensitive to wool. I recently wore these bottoms (and the top) underneath fleece pants while exercising outdoors on a single-digit temperature day to test them out. They were very comfortable (not at all restricting), didn't cause itching and kept me warm. I typically wear size 2 pants and the XS fit well. They're snug but I want a close fit since I'm wearing them underneath other pants. Having said that, they're very attractive and not too tight, so I can wear them alone if I choose. Very satisfied!
