[ I received these as a Christmas gift. I love them under my bibs for snowboarding! They ’ re tight but flexible and comfortable. They keep me warm on the mountain.

5 shellydk
[ I could go on and on about this whole line from Smartwool. It's their best thing in a very long time and I 've been a fan for years. The material is very soft, has a great but comfortable fit. These bottoms also have a nice wide and sturdy waste band so there is no bunching or other uncomfortable nonsense in that area. These are very warm, so perfect under a shell pant or bib for alpine skiing, but I do n't think I would wear them on a tour.

5 Hmae
[ Love the style. These are very warm and keep me toasty on those cold days. Would recommend to anyone looking for a quality under layers... very cute!

[ I highly recommend these for all of your snow adventures. I wear mine directly under my snow pants and they work perfectly for warmth and movement. This base layer helped me survive snowboarding in both Colorado and Canada. Buy a pair, its worth every penny!

5 Jordan

Hike, run, great fit! Happy with them. I am usually wear a medium but with this model maybe Large.

5 Kasi M.
These are great hiking and every day tights! Based on another review, I thought they 'd be softer. But make no mistake, these are technical feeling tights... like running tight material. Definitely not a bad thing, just not what I was expecting. Regardless, they 're amazing tights and fit like a glove.

5 RMFAM
[ These leggings were purchased as a go anywhere do anything legging and have certainly lived up to that expectation. I am very impressed with the quality and durability of the material, the seams are tight and executed very well. I would recommend these to anyone looking for a legging that is a cut above in all ways. They are built for adventure and yet are still very comfortable and enjoyable to wear.

Went hiking in the Lake District and discovered my abisko tights were too large. Fortunately, I found a Fjallraven vendor and found these tights, which turned out perfect as I need a bit more insulation. I love the feel of these. They kept me warm on some pretty brutal days. They dry quickly. I am absolutely in love with Fjallraven tights, and these are a new favorite.

5 Alain
After 2 years wearing these in most color( I own 6 pairs), I can promise to the guys out there the thickness of the tissue finally allows a pair of tights to be worn by men without the ‘ bump ’ showing. Humble yet sexy. I am 6 ’ 3 ” and 100kg and started with the L. Actually the M even fits. Pricy but unkillable.

5 Carmen B.
First let me say that I 'm not a person who wears tights- never have been- but these have changed my mind. I was on the fence about ordering for the longest time and I 'm so glad I finally did. They are thick enough that they feel more like pants to me and oh, so comfortable. The waistband is high, but not too high and the overall fit is just perfect. The leg pockets are deep and secure and the reflective piping at the ankles is a really nice touch. I had thought I might need to wear long underwear with them to be warm enough, but the wind proof panels are a life saver and they are plenty warm if you keep moving.(* An added bonus is that dog hair does not stick to them!) I 'm 5' 6, 140 lbs, average build and the Medium fits perfectly( In the Keb's I wear a 38EU)

5 Shellbell
[ These are great outdoor/hiking leggings! They are warm and seem durable so far. I live on the Northern California coast where it ’s cold most of the year. These leggings are perfect for exploring in! Love them:)

4 WWECO
[ Love the way these pants fit! I always love the look of Fjallraven pants, but these aren ’ t as warm as I hoped. I ’ ve used them in lower temps( 20- 30 ’s F) and my legs are cold to the touch. I definitely have less expensive rights that keep my legs warmer.

I already own many Duofold items and getting the leggings was a no brainer. I like the excellent quality and the warmth it provides. The fabric is very stretchy without being too constricting. It has a fly for those who use it. The fit is perfect.
