The X3 Backdoor is a 30-liter backpack for mountaineering and mountaineering skiing: the ideal model for "fast and light" tours. The Backdoor opening in the back allows easy and immediate access to all the material, even the one located at the bottom. Made of lightweight and resistant fabric, it has an attractive design. Its wide external and lateral net pockets, the large capacity pocket on the hood and the belt pocket allow you to have all the essential equipment at your fingertips. The Xpress system allows you to hook and remove the skis from the backpack without having to take it off. The belt and the chest strap have the EZ OP buckles (exclusive of C.A.M.P.) of easy opening. With EZ OP buckles, it is only necessary to remove the red bolt, which is easily operated even with gloves on, to open the backpack immediately.
