Built by request and in collaboration with our guiding friends in Nepal, the Halka, in both 55L and 70L volumes, are sewn up with a trusted blend of Dyneema Composite Fabrics and just the features required to safely summit the world's highest peaks. For going solo or with a group, the Halka 55 can accommodate a single oxygen bottle in its interior with plenty of room for other required essentials. In a guiding role, choose the Halka 70 with its exterior pockets that can carry two bottles. Both packs feature a removable lid with zippered storage, a dual ice axe carry system, a removable gear loop and pocket hip belt, and multiple other ways to secure tools and gear.
