Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

Best base layer I own!!! Good breathability and soooo warm and cozy. Will buy more! #Sweepstakes

Outside walking the dog, inside doing yoga. My second pair.

I use the merino base layer as tights/leggings, occasionally with pants over them. This weave of merino wool is wonderful, and I have allergic sensitivity to rough wools even to the point of getting hives from prolonged wear. These tights are soft, smooth, stretchy, and warm. I can wear them all day. They're a good fit too. I'm 5'9", 140 lbs, 35 inch waist and tummy, 38 inch hips, muscular calves. The large fits fine. I tried on my daughter's medium and that looks quite sleek and fits too, but starts to feel compressed in the waist and calves after awhile. The large is slightly looser, not much, but it's comfortable and attractive. I wear short merino wool skirts and boots with it, and that's a winter staple until temperatures get into the mid twenties and windy, and then we go for pants.

It's such a sleek fit that I'm wearing them with a skirt for dress up! I usually buy mens bottoms as I'm not very curvy between waist and hip and mens bottoms tend to have practical pockets. Love the color choices.

Warm. Comfortable. Great fit.

Perfect fit. Great warmth.

Okay, I'm basically always cold. I wore these on a shirt 'let's get the dog in the snow' hike yesterday and it was 24 degrees out. Over the base layer I had my lightly insulated snow pants (which I was cold in last year) and I stayed warm the whole time. And did not get too hot! Wool's warm when wet, temperature regulating amazingness has blown my mind again. I've worn these a handful of times now and they haven't stretched very much (and I know when washed will return). I am 5'3 and 110 and got the XS. I almost wish they were about an inch longer, but that's what socks are for I suppose.

Fits like a dream, and looks wonderful with a big sweater or tunic. The color is my favorite blue, with enough green in it so the leggings go with lots of color. And, of course they keep me warm but not sweatydang I love smartwool. Plus NO ecologically damaging spandex!

My first base layer so I don't have a lot to compare to, but I really like the fit (though I wish it was more high waisted) and it's kept me cozy so far. Sweepstakes review.

Great to go hiking in under a dress or jeans to keep you warm

These feel great, are comfortable, and look good alone or with a skirt or shorts over them. I have several colors. #sweepstakes

Soft and warm, marvelous to wear when the weather gets cold

I've used these several times under jeans mucking out horse stalls in 20 degree weather. Never once feel my legs ache like they usually do. I LOVE these base layer bottoms!!!! Thank you Smartwool!

Love these!

This is a gift for my sons girlfriend so can not comment on fit however it is beautiful and very very soft. I have purchased many "Smartwool" products over the years and have never been disappointed. Quality is always spot on and worth every penny

Love these! (So nice to have a replacement for my well worn original ones:) They fit well, are warm without itching! #sweepstakes

I am wearing them right now as a base layer under rain proof pants and smart wool sock and Sorrels as it is cold and rainy here in the Northwest California

The best base layer leggings ever! I hate to take them off!!

These are every day, every activity winter wear leggingswearable for both by themselves or layering for outdoor activities!

these are lovely underlayers. i have them in small and medium. my butt was a bit bigger last year so i got the medium for those days when i've eaten too many bread products. ;) i'm an athletic 5'6" 130lbs with a fair bit of booty at times. the medium is snug but gets baggy by the 2nd day of wear. the small fits snug and stays snug. i love them both though. really soft. my go tos for winter.

Soft, warm and comfy!

So comfortable. I love them. Fits perfect. Keeps me warm.

Smartwool quality! They are breathable and warm! Best socks and base layers out there! Smartwool, we love you, please don't change but pretty please could we have a mid rise and/or high rise base layer bottom option? Thanks xx

EXCELLENT fit for my curvy body! Very comfortablewear them constantly for leggings for everyday wear!

I had previously purchased some leggings from Welland, and had to return them because they were a little scratchy. I went looking for a higher percentage will contact, and found it with these leggings. Much softer! The only issue for me is that I am short (5'2") and so they are naturally baggy on my leg as they are meant to accommodate people who are taller than I am. So if you're looking for a sleek, fitted look, and your short, these are not for you. If you're taller, they might be perfect. If you are just looking for soft, warm leggings and you're going to be wearing boots so no one's going to see the excess fabric, go for it.
