Customer Reviews Smartwool Classic All-Season Merino Base Layer Bottom

Wearing it under my black pants helps me stay warm and nice l. I love them.

I like to use these as a layering for colder day, early morning walks. They are not too bulky and when the temperatures are super cold, I like to wear them under jeans and pants.

I use this product to run in or wear underneath other clothing when it's cold. They are very comfortable, true to size and warm. This is my second pair. After two years of wearing them, I finally started getting some wear and tear around the knees.

I use these around the house when it is cold, or as PJs. Have not yet tried them as a base layer, but plan to in an upcoming trip to a colder area.

I am a biologist who works on boats in cold weather. The level of comfort and warmth is unparalleled. This is a staple piece to my winter wardrobe.

I have a mostly outdoor kindergarten. These leggings keep me warm and comfortable all morning! I love them!

Recommend as a base layer. Comfortable and warm for a day of skiing!

I have worn my first pair of these under leggings while walking outside with it in the 20-30s and stayed warm. I ask for a second pair for Christmas. Love them

As both a skier and all weather out of doors woman, I have always depended upon Smartwool to keep me warm from head to toe whenever the temps drop and the winds blow. I have not found better cool/cold weather products to keep me comfortable and warm.

I love these for wearing under skirts and pants -- and as PJ bottoms too. So comfortable and durable.

Comfortable and warm are the primary factors for choosing any clothing and these fit the bill exceptionally well.

Because I'll be on a ship for a couple weeks I need warm clothes that I can wear repeatedly and not worry about washing or odor. This layer fits the bill perfectly.

So soft and thin, perfect for summer backpacking, winter uphill skiing!

Comfortable. Durable and I love that it doesn't get "stinky" as quickly

I recently moved to the Oregon Coast and I wear my Smartwool top to toes year round. Comfy, warm, and also cool - easy to care for. It's my coastal "go to". The only decisions I make are how many layers today!

Excellent layer.

A great first layer. These feel great and are so comfortable I forget I have them on until I get too warm! I have not had them long enough to put them to the long term wear test though.

Soft, smooth, the perfect weight for under dress pants at school! Keeps me comfortable in warm and cold classrooms, and outdoors for 1/2 hour of recess in the snow!

I use this as a base layer for warmer days skiing! Great fit I am 5'7" weigh 128 ordered small perfect fit! Super comfortable, good quality

Great base layer!! Very warm - I wear these under my pants for my walking commute to work in the cold New England winter.

These are light enough to wear under my winter leggings, but very warm. I also love that they are easy to wash.

I love this. I wear it as under layer whe walking in the winter. Keeps me toasty.

These are great for around the house or under trousers outside- thin but warm

I bought these to use as pajama pants and they are great!

Very roomy, soft, warm
