The gold standard of base layers. Last forever and always do their job. Warm and dry, what else do you need on a cold day?

Easily my most used base layer from Smartwool. During my guide season, they are perfect in fishing waders-warm, comfortable and durable. In the winter, they are under ski pants, lightweights when snowshoeing, and under regular pants when shovelling snow! Couldn’t live without them!!
Scotty –
This base layer is great for being out in the field doing trail work especially during cold and wet days. The bottoms are comfortable and give me just right amount of warmth without restricting movement.
Joel –
Live in Michigan so weather is cold in winter, work outside and inside so I needed a base layer that was warm enough and at same time wouldn’t overheat when indoors ! Great product soft and fits perfectly.
TYLER –

Scott –
So comfortable and felt great in the freezing cold.
Kristin –
These pants are a game changer. I’m out in the cold a lot for work, and nothing has been keeping me warmuntil these! They’re thin enough to wear under other pants, and they keep me so warm. I absolutely love them!
Devin –
All day wear

I was very pleased with how well they fit. I’m now thinking about buying more when I get enough to pay for them. Thank you so much!
Matthew –
Excellent comfort and warmth!
Hazel –
All time favorite layering piece for cold weather.
Thomas –
Super comfortable and warm. I have been using the all weather bottoms and two different weights of the 1/4 zip tops for years now and have no complaints.
Alan –
Just wore them for the first time in 20 degree weather downhill and backcountry skiing in New Hampshire and they are fantastic! Warm, breathable, and comfy!
Thom –
I haven’t worn them for activity yet, but they feel great when I try them on. I feel like they’ll make a great addition to my camping gear. Thank you!
Greg –
These base layer bottoms are my go-to for cold day runs here in Maine (sub 15F). They are totally comfortable and keep my legs warm underneath my running tights. I also put em on at night at home: nothing better to lay around in on these long winter nights.
Nick –
Bought these to replace some polyester bottoms I’ve had for a while…these are softer and much more comfortable. I expect have them for years. I’m 5-10 and weigh 165…great fit.

Always the BEST in base layers and socks (and everything else!)
