Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

I love these leggings as a base layer under my pants in the winter. I just wish they were thicker.

Living in Alaska for 50+ years had many "long johns" and these are THE BEST. Fit great under clothing

This product is so warm and comfortable. I will definatly purchase again and have it every year for the winter season.

Bought these for my daughter to keep her cozy walking to classes. She loves the color too!

I wear merino tops every time I ski. I wear it all around in day to day life. Great for camping and riverside.

These are just like all of the Smartwool I own - perfectly comfortable and warm. I love them! I started with a pair of socks and now I'm a customer for life.

I wore it right out of the box on a cold day. It was comfortable and fit so well. It has the right amount of stretch and is 100% merino wool, what is this sorcery.

Paired with the patterned base layer top, I'm wearing it lounging around after the Thanksgiving holiday. Best at home casual outfit of the season!

Wool base layer is just about the only fabric that is breathable and warm enough for outdoor winters in Illinois/NW Indiana. For the hands and feet there's the trusty hot hands.

I love this base layer for sleeping in, as well as for under pants/skirts in the winter. High quality fabric and construction.

love these pants and Smartwool's thermals in general. My only complaint about these leggings is I wish the wait was a bit higher- this is more of a preference than a flaw though. I like wearing these for active exercise and feel lil they aren't going to stay in place well without a higher waist. Otherwise I love them! Very comfortable and warm, not itchy at all, beautiful fabric.

Planning to use for a trip to Antarctica in January Have worn other Smartwool products with great comfort and warmth

Solid product. They stopped listing g/sqft of material so its tough to compare to other brands.

I'm a skier and love how lightweight these base layers are, but warm! So very comfortable and the color choices are great. Absolutely recommend!

Easy to move, breathable and a great layering piece. I bought the pink and red set. It's adorable and happy with the purchase!

I like the product and I have numerous tops socks, and bottoms and I couldn't live warm enough without them. Had them for years and if a snag one I use embroidery floss and needle to quickly stitch it up. No worries. Any color and shape and my repairs are admired by many. My last product was a pair of women's thermal bottoms XL to replace one that the elastic in the waist had died. Kind of you to replace it but they were muck bigger esp the waist so I gifted them to a good friend with more girth than I. Win win. Love smartwool!

I love Merino wool!!!!

These fit great, look great, and feel great. I sometimes struggle to find wool clothing, especially base layers that aren't itchy or slightly uncomfortable but these are perfect. I bought these as a set with the Women's Classic Thermal Merino Base Layer Crew and I'm very pleased. Barely itchy at all and are substantial enough to keep me warm but thin enough to fit underneath other clothing (like any good base layer should). While I hesitant due to the price, I can confidently say these were worth my money.

My climate is moderate mostly but I was going north for some eagle watching in February. When I saw my first nest, I could not stay out of the car long because of the biting wind off the water. After checking into my cabin and adding my Thermal Merino Base Layer Bottom that fit true to size, I was able to stand the windy cold as long as I wanted. I was toasty warm and very comfortable. They have washed well and held up.

Once it is worn more than once, it stretches and sags. I had to wash in hot water and dry it in the dryer to get it to come back to its original form. Order 1 size down.

I use this as my layer under ski clothes and I'm never cold. They are so comfortable and fit true to size.

The pattern is really cute and they are warm. The fit is okay.

I got this in black and in a large size even though I usually take small or medium because I am liking a loose fit. They are comfortable indoors and also under pants or skirts in the current Eastern cold snap. Very soft.

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!

Super comfy, I just wish the waist was a bit higher
