What Our Gearhead(R) Experts Are Saying:"I keep the Bergtagen 60 stashed in my pack on every ski tour or alpine climb. It packs tiny, adds just enough warmth for the descent or summit push, and layers seamlessly under a shell without bulk."When we move fast in high alpine environments, we need insulation that's light enough to forget but warm enough to count on when the temps drop. The Bergtagen 60 Insulation Jacket M from Fjallraven hits that perfect balance. Designed for mountain activities and built with recycled materials, this layer keeps us warm with PrimaLoft(R) Silver Rise insulation engineered with P. U. R. E.(TM) Technology for more sustainable performance. The ultra-light Pertex(R) shell resists wind and light snow while staying breathable, and it compresses easily into a pack when the sun climbs high. Alpine-specific features-like the helmet-compatible hood, high chest pockets, and glove-friendly zipper pulls-keep this jacket ready for summit transitions, alpine starts, or early morning belays.
