Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

They are wonderful !! I lived in them in Nepal for whole month.

I love smartwool base layers! Merino wool is the way to go. It keeps you warm even when you get wet. I can't wait to take these to Iceland this summer.

Love it

Beautiful print great for any activity

Cute, comfy and keeps me warm. Exactly as expected.

Now med due to 30 lb wt loss. Larges fit but are a little loose. Still warm, comfortable. Will not give them up. If need be will take the size large to a local seamstress for a little trim and tuck

Love the blueberry hill pattern. Really cute under an apres skirt after teaching skiing all day. Soft and warm!

Nice but a bit thick and stiff...too hot to wear beneath insulated pants , even on a sub zero day. And waist could be higher because it keeps slipping.

Love this product worn them today for skiing stayed nice and toasty! Love the fun colors and patterns

Just love these. Purchase at local sports shop depending on what they have and online. Like to support local shops.

Very soft and comfortable.

Great base layer, and I really like the updated style. Improved from previous versions.

I bought the base layer bottoms for use during cold weather activities. So far I have used them under my ski pants. I was plenty warm, but never sweaty, with temperatures ranging from about 10-30 degrees. The material is very comfortable and did not bunch up under my outside layer.

Amazing how keeps me warm. Nothing can ever be warm and comfortable. I grow up in London and I have tried many warm wear nothing can bit smart wool :)

These are nice except for the waistband. It is SO tight! Feels like unnecessary, super-strength elastic! I don't feel great after a couple hours of wear.

Very comfortable, love the material!

This was a gift to our daughter who lives in NYC. She typically has worn your merino base layer bottom for a base layer while skiing. However, the Twilight Blue Heather color is pretty enough to wear under a skirt with boots!

This one saved me. Running in the 30F (below zero C) and it's breathable but not cold. True magic. None of my other gear was as efficient. Thank you

I use this for walking or jogging in very cold weather, Keeps my legs very warm and worth the money.

It is so refreshing to find a truly high quality product - well designed, well made. I want them to last so I have been line drying them.

I live on the north coast of the Pacific Northwest and smart wool fits the bill to keep me warm, especially the base layers!

Matches my Thermal merino base layer pattern crew top. Love it! Super warm without being bulky. Perfect for skiing.

Great for hiking

I love the thicker pair and Smartwool quality.

I love this baselayer bottom! Living in Southeastern Pennsylvania the winter weather is often cold and windy, but this baselayer keeps me nice and warm during my morning walks with the dog.
