A medium/large sized rucksack for alpinism and ski touring made from original Du Pont Cordura. Yellow interior allows you to easily see the contents. Interior gear loops keep hardware close to your centre of gravity and prevent the rack from migrating to the bottom of the pack. Features include internal pocket for Hydration Bladder, two ice tool attachments, side compression straps and ski slots, top pocket has two compartments. Lower section can be split in two, with separate openings. The miniature rucksack called "Manu" may be attached to the front to increase capacity. The mesh back allows some air circulation and hollow at top of sack allows free movement for head and helmet. Length of the harness is adjustable and shoulder straps are contoured.
