The Prolighter 60+20 backpack is designed for demanding use in high mountains and expedition use. However, it can also interest trekkers and fans of mountain crossings. This is mainly due to its extremely low weight. The upper fabric used and the lightweight X-Lighter back™ system play a major role in this. However, this does not mean that you have to treat it "like gloves". The durability of the backpack is ensured thanks to the special treatment of the honeycomb material. The outer material is waterproof, however, to keep things dry under all circumstances, you can add a raincoat or a waterproof bag to the backpack. The backpack has a narrow shape that does not restrict your movement, as well as an adjustable chest belt and waist belt with loops for material. You will also appreciate the adjustable lid with 2 pockets, loops for the ice ax and the helmet holder, a loop for attaching the rope and side straps for fastening skis, mats, etc.
