I have ordered this backpack as a gift. Decisive for buying here was the power wall at the back and the included Rege shell and the good experience to date was Deuter backpacks. He makes a very good, solid impression. All seams are meticulously crafted. It is used daily, mainly riding a bicycle, which makes the network wall substantial returns on the back and the very low weight. The padding on the sides and shoulders top is. Nothing expresses or is uncomfortable, even if it is fully loaded. 22 liters are perfectly adequate for us. Through the breast and shoulder, he remains firm and stable on the back. Conclusion: like us, we reserve the right;)
