The Xeros Jacket is slightly light and more packable than the beefy Kryos but still super warm and up for any alpine adventure. The 800 fill power Down Codex ethically sourced insulation is the warmest on the market and highly compressible to create and small pack size. The Xeros jacket is part of Mountain Equipment’s extended research and Development project with some of the best alpinists in the world.
