The X Vent Zero system offers maximum control and the best possible ventilation with minimal contact with the back. Two x-shaped fibreglass rods on the back of the packsack combine with waist straps to make the supporting connection of the packsack. The tightening and releasing of the system is infinitely variable, which means it can be adjusted individually. If the system is loosened completely, then the backpack can also be positioned to fit close to the back. Thanks to the consistent reduction in the use of materials, this system makes every rucksack a lightweight. The Tatonka women’s backpack X Vent Zero carrying system has been specially developed for the female anatomy and includes curved shoulder straps.
