Snowline SL

Based on our unparalleled Extreme range these bags have been designed for those pushing the limits of super alpine climbing on the toughest routes.

Moving fast at altitude forces you to pack as light as you dare and Extreme SL bags have been custom built for those who demand minimalism without compromise for the biggest projects. Superlight and highly water resistant fabric is combined with the finest down and innovative construction for the lowest possible weight and bulk. Designed for the last great problems on the most remote peaks, these are sleeping bags destined for the cutting edge.
