Working man's best friend
I'm not a hiker or a snowboarder. I'm not likely to climb Everest or compete in a dog sled race across the straits of Alaska. I suspect a lot of you that have happened past this review aren't either. Probably, like me, you work in the cold in the winter, maybe sit in a deer stand on the weekends. I'...

Not as well made as they used to be
I have always loved merino wool stuff, namely smart wool stuff. I have several base layer shirts that I have had and used for years. They are durable and well made, and will last man more years. Because of this, I decided to buy a pair of 250 bottoms. Very comfy, standard long john bottoms. My ...

Great Baselayer!
Great base layer! Very warm and doesn't restrict movement! Highly recommend for anyone outside for hours during winter. Use them during winter days for delivering packages.
Loved it!
We were worried the medium would be too short for my 6'4 boyfriend, but it fits great! He's never owned Smartwool and was blown away with the comfort.

We believe Base Layers make the perfect gifts, although we are a bit biased. Thank you for the kind review too!
I can't get enough of these pants!
These Smartwool base layer bottoms are perfect for camping and snowboarding! The 100% merino wool keeps me warm without overheating, wicks moisture, and resists odors—ideal for long days on the mountain or chilly nights at camp. The fit is snug but flexible, making them super comfortable under snow pants or joggers. Whether I'm hitting the slopes or truck camping in the cold, these are a must-have. Highly recommend!
Fantastic Base Layer!
Fantastic base layer for spending many hours outside delivering packages on cold days.
Poor shipping
Quality is good as usual for Smartwool. Shipping leaves a lot to be desired. It was supposed to be delivered 2/7 finally got it 2/14. Tracking wouldn't open at least half the time. Never on computer only on phone. Will look hard to buy some place else
I would definitely be purchasing again!
Wonderful if working outside in the cold weather!
Best Base Layer Ever
When it's 9 degrees outside wearing these under my jeans sure helps. I especially like that they don't pull the hair on my legs. I highly recommend this base layer or for just laying around home.
Finally got more after 10+ years
I got 2 pairs like 15 years ago and love them. The only wear is a couple of moth holes. I've worn them for everything from being outside all day doing commercial snow clearing, to hiking, to skiing. I finally got some more because I wanted to get another pair into my rotation when I'm on cold weather vacation when I don't have access to laundry.
I have multiple pairs!
I wear these on the slopes or just for chillin! So warm and comfy.
