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.

These are a nice weight for fall and winter around the house. The elasticized waist is good and wide. Note that they sit a bit low on the waist. I’d be happier if they included proper belt loops as the string-to-tighten-method is never of much use if you put anything heavy in the pockets. Material is comfortable, and there is some nice detailing on the knees. Overall I’m happy.

These are my favourite long johns and nothing else even comes close. The fit is perfect for me, the wool is soft and they wash really wash. I’m so glad they come in black now!

These are the best cold weather tights I’ve ever owned, hands down. Great value for money, these lightweight but warm tights will keep you warm as the temperature plummets.

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.
Beautiful colour and fit, very lightweight but still warm and dry. I would wear these every day if I didn't need to air them out -- but like all high quality wool they only need occasional washing which keeps them available and extends their life dramatically. Highly recommend.
Fjallraven makes great quality clothing. This is no exception. Great mid base layer and true to size. I’m 6’3 and 190 pounds. Size medium fits perfect
I purchased the Bergtagen long sleeve top a while back, so when I saw these bottoms I had to complete the set, as the top is excellent quality and fit. I’m 5’9” 155 lbs, 30” waist, 41” chest, medium build and the fit is snug but not at all tight. Due to the finer yet tight weave of the fabric they hold their shape, smooth and comfortable texture, and hold up in the wash ( recommend short tumble dry time then hang to dry) you can’t get much better than Fjalraven!
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.
These long johns are like having a personal heater for your legs.
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
