Millet Prolighter 30 + 10 is a robust and efficient trekking and mountaineering backpack, designed for high mountain activity all year round. Made of polyamide with water repellent treatment it is super resistant and light! The narrow and clean shape is very functional both for carrying all the equipment you may need, and for not hindering your movements, without hindering you in your vertical progressions in an alpine environment. From the top thanks to a lockable rain hood with buckles you will have access to the main compartment of 30 liters, expandable by an additional 10 liters for the outings in which you need more material. At the waist there is a removable belt with material holder rings, while the back is made of X-Lighter thermoformed foam, light and very comfortable. At your disposal there are several pockets that allow you to better organize the load and have quick access to what you need. Obviously there is no lack of supports for trekking poles, ice axes and skis, as well as compatibility with the water bag. Millet Prolighter 30+10 l mountaineering backpack
