An amazingly comfortable, really warm pair of longjohns that are ideal for the harsh winter conditions encountered in the mountains. Really technical pants which balance comfort and performance really well. 

Fjällräven says:

Comfortable base-layer long johns in merino blend. Four different fabrics with different knitting techniques for the optimal combination of warmth, ventilation and freedom of movement. Perfect for all kinds of outdoor pursuits with varying levels of activity, and extra practical on long trips as wool resists bad odours.

Fjällräven's Bergtagen Longjohns are a well designed and well made set of baselayer pants to keep you warm in the winter. The body-mapped design has resulted in different materials across different parts of the body to maximise warmth, breathability and comfort. They work really well but admittedly, they are so warm they need only be worn in the coldest conditions.

The blended material that makes up the warmest sections which keep you rear and lower legs particularly warm are made with merino and sysnthetic to balance the performance of warmth and breathability. The thigh and calf areas are covered in a wool mesh to allow maximum breathability when you are working hard up the hills and mountains while still providing enough warmth when you're at a standstill.

The extended elasticated sections up from the ankles does a great job of keeping them in place even when you're stretching out. The elasticated waist band is also really comfortable with a softer feel to the inner.
