Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

Thin enough so they don't compromise movement, fit easily under other pants. I wear these under goretex shell pants and am toasty through the low teens.

Very comfortable and warm. My only complaint is the length. I'm 5"8 and they should have longer lengths for us tall girls. I do wear my leggings with winter boots and tall wool socks so my ankles were covered. Taller lengths please!!!

Delightfully soft and warm. If I were an animal, this would be the fur I'd choose.

I love the quality of the smartwool products including these tights. They are warm, not itchy (and I am very sensitive to itch) and fit as expected. If in between sizes I think size up. I think they are expensive for what they should be. Also, the pick up every lint and hair, and u don't have pets. That being said, I love them but buy less because of price.

perfect for layering. i spend a lot of time outdoors. smart wool 250 base layer bottoms keeps me warm during the cold weather months. they are comfortable not scratchy like other wool garments I've worn. the fit is perfect. i purchased a small. 5' 5" 120 lbs.

Love everything Smartwool! When you live in the Icebox of the Nation, Smartwool is a must!

Very warm under layer

Perfect for under snow pants or lounging around. Comfy, not itchy true to size.

Great for skiing.

Perfect temperature control.

why have I denied myself these amazing leggings for so long? Regardless - I didn't have to regret my lag time one second more with three day shipping that was more like only two days. So comfy and warm. Might not take them off until spring

Sometimes I need to walk the dog before the sun comes up and I was so warm and toasty the entire time. Definitely purchasing more items from SW!

Incredibly comfortable and it kept me warm during cold rain while fishing. It also wicks away moisture really well which is a huge plus in the PNW.

5' 6" and 128, perfect fit with the medium. Fitted, flattering, comfortable. Great base for skiing - wore this under non-insulated snow pants and was comfortable on a 30 degree ski day.

Bought these to replace a VERY well worn pair of Smartwool longjohns, which got a little too much love from some woolmoths last year. I was happy to see these are even better fitting than my old ones. Same great level of added warmth under jeans.

you can wear these as leggings or a base layer

I wear them with dresses. When I received them, I thought they were not heavy enough to be warm, but they are. I love them . Well worth the money.

This was my first pair of base layer bottoms from Smartwool and I'm very happy with them. I've been wearing them when I walk with one of your tops and they are exactly what I've been looking for. They fit well and keep me very warm.

This was a gift for my daughter in law who lives in Portland, OR. She loves these, wears them all the time. She was so comfortable that she forgot to put her pants on !

I love these! I have 4 pairs. I have never been comfortable with synthetics. I have thin legs and tried to build them up to no avail. They get cold at 55 and I start wearing these. Yesterday took a long walk at 30 and these were nice and toasty. They are lightweight, so you can wear them under anything! One pair of 4 years old and just showing wear.

I used these for ski touring (under my waterproof layer) for colder days. They're comfortable and cozy and wick moisture well. #SmartwoolLove

Love this base layer. Super comfy, warm and breathes well. Great for ski touring.

These are very high quality base layers. Compared to my Icebreaker base layers they are much softer with no itch at all. They are considerably thicker and warmer than the 150 weight. I think they will be perfect to wear while shoveling snow and skiing. #SmartwoolLove

I use these for all my winter outdoor activities. I throw these on under a water resistant/windproof shell and they are fantatstic. I use them only for when it's getting down closer to -20 or else I overheat after a while of hiking. They are very comfortable and even though I have short legs it's easy to roll them up at the bottom #SmartwoolLove

These base layer pants get the most use in my wardrobe - they are an absolute must have piece for anyone who spends anytime outside in the negative temperatures. These are always on me when I'm skiing, snowshoeing, etc. but get the most daily use when I walk my dog in the bitterly cold Alberta winters. They keep me warm, without soaking me in sweat and are incredibly durable. Absolutely recommend these for everyone to have in the winter! #SmartwoolLove
