Mountain Equipment Kryos Men's Jacket

Mountain Equipment's Kryos Men's Jacket is the optimum combination of warmth, protection, and minimal weight, purpose built for winter alpine climbing and super alpinism in the greater ranges. Informed by feedback from some of the world's best alpinists, it was designed to make the cut on the hardest routes at 6,000 and 7,000 m and the biggest modern alpine winter lines, whilst offering a much greater level of warmth and protection than anything that came before.

The key to this lies in the development of Firestorm construction: a Drilite Loft drop outer shell that radically reduces heat loss whilst offering a much greater level of weather protection, vital on the most committing routes. Underneath lies a hybrid layout of stitch-through and pleated baffles optimised to give the absolute maximum loft and warmth from 234 g of goose down. Up to 20% greater warmth with up to 20% lower weight, with far lower water and wind ingress.

The Kryos has been used on Paul Ramsden and Tim Miller's Piolet d'Or winning first ascent of Jugal Spire, Tom Livingstone and Matt Glenn's first ascent of the North East Pillar of Tengkangpoche, Freja Shannon's multiple hard first ascents in Arctic Norway, and Uisdean Hawthorn's Piolet d'Or winning first ascent on Mount Robson's Emperor Face.
