Ortlieb X-tremer 113L

"The X-tremer 113L from Ortlieb is the ideal companion for anyone who wants to take a lot of equipment with them on their expeditions or bike tours. With an impressive volume of 113 liters, this backpack offers enough space to store everything you need and more. Thanks to the contoured straps and the practical roll closure, the rucksack is comfortable to carry and can be securely closed. The rucksack is made from a robust 3-layer material, which is not only hard-wearing but also water-repellent and therefore fulfills protection class IP 64."
"This unisex backpack is specially designed for adventurous people who do not want to compromise on comfort and safety on hiking tours or other outdoor activities. The Drings are ideal for lashing or locking and also offer the option of safely roping down the rucksack. The height of the rucksack when closed is 3-4 times rolled up, for the unclosed height you should add about 15-20 cm, which offers additional flexibility when packing."
