Customer Reviews Smartwool Classic Thermal Merino Base Layer Bottom

I purchased this item so that I could dwindle down the amount of sleep layers I wear while winter camping. I wanted a quality, warm base layer that would hopefully eliminate 3 pairs of sweat pants/leggings. I have not tested the pants out yet, but just wearing them at home I can tell that I will 100% be satisfied with my purchase.

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

I am 5'11" have a hard time finding base layer pants long enough, these are plenty long.

Warm and cosy base layer. Fits well under clothing, without bulkiness. Washes well. Pretty color (pink!).

Works as advertised! I wear these underneath work pants to stay warm outside in below freezing temperatures.

Wear these under jeans or dress pants. Wide flat seamed waist is as comfortable as I'd hoped. Weight is thicker than silk or polyester leggings so if you wear with dress pants better to choose wide legged style not skinny or body hugging. Comfortable but am still aware I'm wearing wool.

I've been using these for cold weather walks and hikes. They're thin enough to fit under hiking pants but keep me plenty warm. I was borderline M/L, went with M and they fit so comfortably. Not too tight. Highly recommend.

It is a perfect product for winter

These were comfortable all day in the cold. Great fit. Glad I had them when it was so cold out! Love merino wool.

I admit I use these for bed. I get very cold at night and the base layers help me regulate body temperature. The small is a tiny bit snug but the xs didn't feel that snug which is why I didn't go medium. Such a high quality and to me, worth the extra price. I hope it lasts me for years to come.

These are great for all types of ski days. Just wearing these thermals and insulated snow pants, my legs never get cold! They also stretch so I can pull them up above my ski boots. Sometimes I wear them just out and about. Overall, great product and will definitely be getting another pair!

Great fit, perfect for under jeans or pants to add an extra layer.

I'm between a M and L, bought a M and it fits perfect/comfortably. Can't speak to the longevity but they feel very well made and are definitely warm.

Not itchy, very warm, and comfy! Bought my usual size of XS. At first, I was worried they would be too small but they stretched a little overtime so I'm glad I did not size up. Measurements: waist 24.5 inches and hips 35.5 inches. I bought these as a base layer for snowboarding but now I wear them around the house and at work when it's cold!

LOVE TO WEAR THESE SKIING AND SNOWSHOEING!

I can use these as a base layer when out in chilly weather, or casually at home. The moisture-wicking properties of Merino wool are second to none! Perfect temp always!

Nice waist design.

as leggings under skirts

Very comfortable and warm, they are worn outside in colder weather for walking and other activities

I'm 5'6" and 115 lbs and the XS fit me perfectly. Highly recommend for all winter activities!

Warm, breathable layer. Perfect for winter sports

Skiing, great warmth and comfort and moisture wicking

I love these base layer bottoms. This will be my third pair; they tend to wear through after a winter of hard use, but I like the way they fit.

Love love love! Not scratchy at all and so warm.

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.
