Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

Very comfortable. Sizing is accurate. Very warm and cozy currently. Can't wait to see how warm they keep me all winter

I bought these for a trip to Scotland this winter as a base layer. They are very soft and not itchy like some wool base layers I have found.

I absolutely love these merino base layer bottoms. The pattern is so pretty and the material is super comfy. I look forward to wearing these (bought a solid colored pair as well) in the cooler New England Fall and Winter months.

Comfortable, keeps you warm. Excellent base layer for cold days or rainy days while camping. I love to sleep in them and add outerwear overtop in the morning.

These are super cozy leggings with just enough stretch to be forgiving. I love this pattern, too - it's almost black even with the snowflakes, which give it a little texture. I look forward to wearing these in Iceland.

I just LOVE this product. I wish I could wear it all the time. It's so soft, so comfortable, so cozy! And the colors are fantastic!

Wore them on a chilly day and wasn't chilly at all. Fabric is exceptionally soft. They are a bit long for me (and I have long legs) but I can live with that!

Quite comfortable! Doesn't lay as flat as leggings but obvious benefits over those as they are made of a natural material.

Great fit and warm.

I use these to ski so I don't freeze out there on the mountain.

I wear these by themselves as my bottom, under shorts, and under skirts. I wear them sometimes for PJ bottoms and ALL the time for day wear. They are PERFECT in the morning under my shorts and then get peeled off as the day warms up. The are like a hug for my legs. They are SO SOFT and comfy. I was wearing the foggy pines under my shorts at the athletic club and a friend was admiring them. She now has a pair of her own and is just as in love with hers as I am with mine. I have 5 of these in all different colors. My biggest challenge is deciding which color to wear in the morning.

Comfy sums it up in one word. I love, love, love these and have multiple pair in beautiful colors that I just wear like regular leggings many days of the week. I have gotten many compliments on them. One friend was looking at them from afar and just went on and on and on about how much she loved them. I, of course, told her how she too could have some. Cheers!

This is the best base layer or can be worn by themselves! Keeps my legs warm on trail runs overnight even down close to freezing. Best of all, they are so soft and cause zero chafing! Highly recommend!

Got these to use for a rock climbing trip. They feel warm, but light enough to fit under my climbing pants

I bought these leggings for stay warm on the mountain while skiing. They fit well and are cozy

I could probably throw out all my other leggings now that I own the classic merino thermal base layer bottom. I know this is a base layer, but the fit is so amazing that it has now become my go to leggings. I have a big booty and the way the back is designed accentuates my figure and makes my rear end look smaller. I tried to include an up close picture for reference. I wear them with outfits as well as hiking/workout pants, and of course it's intended use as a base layer. While the vibrant colors offered are pretty, I hope Smartwool will make these in more basic colors for every day wear. I will be ordering more black ones soon and I really hope to be able to get navy, olive, and burgundy soon.

My favorite base layer. Warm but not hot. Soft enough to sleep in too.

Love these. I use them when riding my motorcycle. The fit well and are very comfortable! I would buy them again.

Good quality, comfy and warm

Have purchased same product previously. Couldn't find any locally, so ordered online. Same great fit and look. Thank you!

I purchased these along with the matching top to wear as warm pajamas while camping in Utah this spring. The perfect solution.

I like the warmth and fit of the classic thermal merino base layer bottom. They are perfect for chilly mornings and pair well with my Smartwool socks.

very comfortable and warm

Love it the fit is perfect

I use these long underwear for skiing. They're perfect for cool winter days under my ski pants. I use a thicker pair for very cold days. I love the snow flake pattern on these pair that I purchased.
