Mammut Aenergy 18

"The Aenergy 18 from Mammut is the ideal companion for anyone who likes to travel light and fast, whether for hiking, leisure or everyday use. This versatile backpack impresses with its lightweight yet robust design, which is largely made from recycled materials. With a backpack volume of 18 liters, which can be expanded to 20 liters thanks to the practical roll-top closure, it offers enough space for all your essentials"
"The ergonomically shaped and wide shoulder straps ensure a high level of comfort, even on longer tours. The backpack is also water-repellent and offers optimum carrying comfort thanks to its breathable back padding. The well thought-out pocket concept with two spacious main compartments, a meshuuuu pocket and two chest pockets makes it possible to always have provisions and other important small items to hand. Additional safety is provided by the reflective elements, which ensure visibility even in the dark."
"Another plus point is the hydration system compatibility of the Aenergy 18, which allows you to stay perfectly hydrated on the go. With this backpack, you are well equipped for any adventure, whether by day or night."
