The weight of a rucksack must lie in its contents and not in the sack itself. The rucksack can be folded away into its own inner pocket and only reappears when needed. It only weighs 455 grams! Made in Nylon Rip Stop in the exclusive Grivel yellow/black. All frills removed to reduce weight and bulk. New padded shoulder straps and padded back panel. Two ice axe attachments. The two straps on the front can be used to attach all means of equipment: skis, snowboard, poles, tent… This new standard will be appreciated where the air is thin and every gram weighs like a kilo.
