Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

I love the color of this base layer. I wear the bottom/top underneath my work outfit as a clinician in healthcare. I will also be wearing them skiing when I get to the mountains. The pants are not too tight or too lose. They fit well on 5'6 frame. I enjoy the feel, warmth and the ability to not have to wash them after every use!

My go-to for cold wet weather.

Use as an undergarment for running in the cold weather. Absolutely love the warmth it provides

Love the patterned ones. Warm for skiing and for winter boating and look cute when you throw the insulated skirt over it for apres drinks or running around town! (I wear a large because I am an athlete but I'm not that tall, so they seem a little long for a 5'6 girl. But I don't personally mind it.)

Love these bottoms! Perfect for added warmth under clothes or as leggings with a longer top.

Good sizing, comfy, warm without being too bulky, and good moisture wicking properties. They are a bit on the longer side, but I have short legs, and it's not an issue. I've ordered another pair.

comfortable, quick drying, and doesn't hold smell after a day of wear!

The Women's Classic Thermal Merino Base Layer Bottom is a perfect base layer for winter adventures. The merino wool is soft, breathable, and incredibly warm. It fits like a second skin, providing excellent insulation without restricting movement. A must-have for staying cozy on the slopes or during any cold-weather activity!

So warm, so comfortable to put on and take off. Beautiful color. Feels good against my skin, no itch.

Love these warm bottoms.

Great fit, and I love the color!

So comfy! Not too warm as an active legging but keeps you warm even if you're sweaty!

I use this as a base layer in cool to cold weather.

I absolutely love the pattern and how cozy the fit feels!

Love these for skiing, snow shoveling, or hanging out on cold days. Fit and comfort has not changed. Snowflake pattern is cute.

I bought these to go to Nepal later this year. Haven't worn them in extreme climate yet, but here at home, they fit great, are snug but not tight, not itchy and comfortably warm.

This medium is a lot larger than last year's medium and the fabric is a lot heavier. Still works though.

These are my go-to base layers for both touring and resort days. They're warm, with a good fit and they're not itchy. No complaints!

Extremely comfy and well made. Wear them under clothes or with a long top. So nice.

These thermals are durable, comfortable, and most importantly keep me warm. The fit is good and they aren't itchy. Definitely a winter staple!

My go to for base layer cool weather long underwear. Love the fit and love the colors. Waist is not too constrictive and the fabric is soft and durable. I'm a size 10-12 and the large fits great with enough stretch to be active. Bicycle Happiness!!

Fit is very good, was looking for a companion lower set to go with my 1/4 zip top. Construction is top quality and can be layered for additional warmth.

I use these for sleeping while camping in cold weather. Also use for a base layer for hiking in cold weather. They keep me nice and warm.

In love with these pants/ layers! Best layering piece for any and all ice fishing in Montana!!

These will keep my legs warm as a comfortable and fashionable layer, paired with my new Smartwool Smartloft skirt. They fit perfectly!
