Versatile, durable and with expedition-proven features, it excels whether backpacking at altitude or ski touring through winter mountains.

Inside the bag, a 100% recycled Supersoft 20D lining fabric with PFAS-free DWR offers breathability and durability for comfortable nights and a long lifespan, while a full-length Gemini entry zip baffle practically eliminates heat loss in this vulnerable area and is stiffened so it wont catch in the zip.
