Why We Like The Smartwool Intraknit Thermal Merino Baselayer Bottom

There's so much to explore in the winter, so we suit up in waterproof shells, but not before slipping into the Smartwool Intraknit Thermal Merino Baselayer Bottom. These midweight baselayer tights keep us ultra-warm for snowshoe hikes and resort adventures. Merino wool offers its thermal magic, keeping us simultaneously warm and sweat-free. And Smartwool's innovative Intraknit technology enhances breathability and dry times for maximum comfort while we're on the move.

Warm but snaggy

Familiarity:
I've used it several times

Bought these for the husband, and he reports great things about comfort and warmth, but the fabric is fragile (yet fairly thick, oddly enough). He found several snags after just one wear and wash (and nothing in the laundry load could be blamed). A couple of the snags were significant. Future washings will be done in a mesh zipper bag.

Wear everyday for work, all winter long- Pennsylvania.

[This review was collected as part of a promotion.] These are the best base layer for work everyday. I am an arborist and own a tree company in Pennsylvania. These base layer bottoms are the best I've ever owned. Highly recommend.

Yes

[This review was collected as part of a promotion.] I bought them for my daughters boyfriend and we are returning them, as they are the wrong size. I know you are crediting my credit card and I gave him the money and they will be reordering them in a medium instead of small.

Life changing

[This review was collected as part of a promotion.] I live and work in Alaska, a lot of it outside. I no longer have to wear multiple layers underneath a uniform to stay warm. These are awesome.

Will buy again

First time purchaser of smartwool. Been committed to UA coldgear for years and still committed. After three weeks 240 miles of gravel bike riding unwashed leggings 30-50 degree temps I like them a lot. Super comfortable against the skin. Never gave odorless material any thought but for those who feel odorless is a plus these are def odorless. Great job wicking sweat off the body. I have the XXL, should've gone with the XL. But I'm a first time purchaser. They hold up well. I don't have to stop my bike and feel the need to pull them up. I'll be purchasing a second set XL I'm 6"1 215lbs. My guess, these with the UA it'll be more than a month between washes. I wash my UA's delicate/cold hang dry. I'll do the same with these

Definitely would buy again - very well made and watm

[This review was collected as part of a promotion.] This is another of my first smart wool products. Again, very well made and warm. My only quibble is that there is no fly. The other baselayers by smart wool that I purchased have a fly.
