Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

Perfect fit and so comfy

These are some of my back country base layers and I love them. They fit well, keep me warm, and are soft.

Very comfortable and warm. I purchased the charcoal gray color and they fit better than the black. They are slightly loose in the knees and stretch a bit with wear but I’m okay with that. I could live in them all winter.

Order down a size they do sorta grow. But I brought a ton of layers skiiing and I just kept wearing this one the whole time. It hand washed up good in the hotel and was totally dry by morning. I used wool lite cleaner.

I like the bottom’s quality of material. Light and warm. But they are too long. I bought XL but probably I should have buy large. I am 5.4 and they are too Long. No opinions when I bought on line. One size. I kept them.

These fit well. They are not tight like compression leggings but they are nicely fitted. They are a little scratchy, which is normal with wool. I haven’t had a chance to use them yet; but I look forward to them keeping me warm in the cold weather and for layering.

Really soft and fits great

Warm, fits well, not itchy!

Fit is perfect. Lightweight and warm.

Excellent but we ordered the wrong size and returned it

Winter and skiing is on my mind with this rich new color as my base layer.

Love these, got the turquoise color. They fit nicely, the waist is a little low, but it's ok.

These are great on cold winter days and they fit well under my clothes without adding bulk. Just what I need to survive our northern winters.

Love the bottoms as well as the tops!! One recommendation is to please reinforce the groin area as it tends to get holes and tear.

Great fit, launder nicely and maintains shape. I have 4 pairs wear them 3 seasons.

Wonderful for winter hiking!

Needs a little more stretch for movement, but kept the warmth in!

under ski pants and outdoors for cold weather

Perfect ski underlay. Runs true to size. I am a size 4 and the small was perfect.

These are so soft an comfortable! They have so many options it was hard to choose. Everything is fairly pricey, but good quality and comfort. Haven't used them for skiing yet, but they seem warm.

Skiing, winter walks, evening tennis

1000 times "yes". Buy these. Warm, comfortable, super cute color, and able to fit underneath run pants or jeans. If you wanna be warm - BUY THESE! Fits true to size.

These are best tights for winter walking. They keep me toasty below 25 degrees; move with me in every direction and don't pill. Very grumpy when they are in the wash.

Wow. Exactly what I was looking for. Slim, legging style waist band, minimal branding, comfortable fit, and very warm. I'm 5'8", 125 lbs and the small is perfect. I bought these specifically for Nordic skiing. I wear them layered with athletic leggings on top, keeping me toasty in 25F weather but not overheating once in motion. The quality is wonderful. Super happy.

These are the BEST base layer pants I've ever tried. I wear them several times before washing them and I love them so much, I want another pair ASAP.
