Perfect Fix

All winter long these babies did everything I asked. I originally bought them as a replacement to my age old under armor and thought I'd try out the 3/4 thing while skiing this time around. I'm never going back. They're warm when the temperature drops but they are a mid-weight layer so one cannot ask for too much. All in all a great buy! I'm 5' 10", 148lbs and the medium is a little loose but works well regardless.

Sheep are lucky

Well, I love these lonjohns. Warm, wicking, wonderful. Just great. They don't smell after days without washing, regulate temps like a champ, and are just all together very comfortable. I've worn them as a single layer under softshell pants for some stormy snowshoe camping which was a great idea. I've worn them under Carhartts for cutting wood, which was also a great idea. What I'm saying is you'll want to find excuses to wear them. One thing I did notice is you'll want to get some boot length socks, as hiking socks are a bit short to hold down the bottom hem from riding up. So, grab a pair of these or
and you are in for a treat.

Very dissappointed

These developed numerous holes and tears even though I've worn them less than 10 times.

Talk to Smartwool! You've got a lifetime warranty with them. I've got no holes after jeez...dozens of wearings.

I have a pair of these and like them quite a bit, but I would like to get something similar, with the boot top length, that is warmer as well (preferably wool, but that isn't absolutely necessary).

Snug and Toasty

Nice warm underwear that fit above your ski boot. Heard folks talk about not want to have your longjohns in your boots ... just your foot and socks. Well they were right. No tight spots, wrinkles, etc. in your boot. These fit and look more like a compression pant, but are amazingly comfortable in all the right places. I am 5' 8" and 185; ordered the XXL and they fit well. If I were you I would error by getting a larger size because of this. Tried several others like this; none as good. Great product.

Is this tight as the tech synthetic bottoms?
I'm looking for something that it's not tight or snuggly but not too loose so you can wear it comfortably under cargo/walking/street trousers and I like that they don't go all the way down.
I wear 38-39 waist trousers

Responded on

I really like the fit on these, but they do fit tight like tech clothing. I am similar in the waist size and they are snug all the way top to bottom. But I love them for warmth.

Responded on

If you want a looser fit you can upsize without being completely baggy. The stretchy knit of the wool will still work for you.

Hi. What size should I go if I'am 35-36"...

Hi. What size should I go if I'am 35-36" in waist. I read many reviews on the net about Smartwool baselayers and some people say that after washing, they get shrinked! Thanks!

Responded on

Large should be right. They only shrink a tiny bit and stretch right back. If you like your base layer to be loose go with XL.

Worked great for my husband on this ski trip (underneath unlined GoreTex pants). A bit tight in the calves area compared to the rest.

If I wear a Medium in Capilene 2 bottoms but have a 34" waist, what size should I order?

Responded on

You're on the border. Med if you want a snug fit, large if you want 'em loose. I'd lean towards the med.

How tight are they suppose to fit. My waist size is 31 inches, small or medium?

Responded on

Hi. You´re gonna need Medium cause its for waist size 31-2 in. Small would be a it thight , perhaps.

Comfortable, non-stink, and does not restrict movement. Way better than any synthetic I've ever used... keeps you drier, warmer, and doesn't stink as much. I use these as my general snowboard baselayer, as well as when I'm cold at work or running. Super versatile and well worth the cash if you have it.

Even with the hefty price tag, if you are in a position to use base layers often, you will actually SAVE money as you will not need to wash these as often thanks to Merino wool's inherent antibacterial nature. A lot of synthetics have something similar, but it will wash out eventually. With these, it's a part of the fiber and will last for the life of the garment.

Just got back from a winter camping trip in northern CT, and these pants were perfect! Temperatures at night dropped to 27 degrees, and with just shell pants over them I was comfortable. Very comfortable as well, great waistband and very soft feel. Temperature regulation was superb (from strenuous hiking and gear laden ascents and descents to peeing in the snow at night). Stink control is phenomenal, just washed them after a few weeks of wearing almost everyday, and they still didn't smell. Highly recommend, buy some now (better than capilene)
