Thermal-mapped zonal insulation puts loft where its needed most. Lightweight, sewn-through construction in the upper half of the bag layers easily over a jacket and provides maximum versatility. Full baffles provide extra warmth from the waist down. Fill is eliminated in the back of the bag, where a mattress provides full insulation from the ground.

The design is ideal for side sleepers or anyone who wants more freedom of movement without adding extra weight to their pack.
