What Our Gearhead(R) Experts Are Saying: "This is the piece I grab for ski tours or alpine approaches when I know I'll need insulation that's warm but never bulky. It layers easily over a shell or under a belay jacket, and the water-repellent face keeps it functional even when conditions turn."In the alpine, we choose our layers carefully. The Bergtagen 130 Insulation Jacket W from Fjallraven delivers the lightweight, high-performance insulation we need for fast-moving mountain missions. Whether we're skinning above tree line or racking up pitches on a cold north face, it offers warmth without weight, breathability where we need it, and durability where it counts. The recycled polyester shell fends off snow and wind, while the P. U. R. E.(TM)-powered PrimaLoft(R) Rise insulation maintains loft without excess bulk. Streamlined design keeps movement unrestricted with pre-shaped sleeves and a dropped rear hem, and thoughtful features like high-mounted pockets and helmet-compatible hood keep it alpine-ready. When we don't need it, the whole thing compresses down into its own hood and tucks away in the pack until temps drop again.
