The Fjallraven Men's Bergtagen Long Johns is a comfortable pair of leggings in merino wool for alpine trips in the spring and summer. Wool wicks away moisture and helps keep you at a comfortable temperature when activity levels vary. It also has a totally natural resistance to bad odours. Just like all our Bergtagen base-layer garments, they are made from merino wool that is mulesing free and can be traced back to its farm of origin.

Perfect base layer in 100% wool. I use it in many winter activities, backcountry, alpine and Nordic skiing. Also great for colder hikes. Very breathable and doesn’t get too warm.

I was amazed by the quality and the fit . Great product. I might buy another set
I’ll need something a bit heavier for Jan Feb but these are great inside and out side up to about -10c. They fit so well that I forget I have them on.
These are sweet tighhhts
I already had the bergtagen thinwool ls shirt, I loved it so much I needed the long johns ! The material is very smooth and soft, quite elastic. It keeps me warm without hindering movements or feeling too hot, and doesn't get stinky. Just the perfect base layer for the winter.
Price is fair for a top quality productIn description it said for spring or summer but I use it in winter under my vidda pro or keb ecoshell trouser (fjallraven) and for a range of 10 to -15 celcius this long john is perfect. Just enough warm, Dry fast and very comfortable (like you wear a pyjama) Perfect for hiking, fatbike or cross country sking. For alpine sking or snowboarding I recommended the warmest long john from fjallraven with a isolate pants
