Wir lieben Berlin! The TXL Backpack is inspired by the Berlin-Tegel Airport (TXL) in Germany. The exterior is coated with polycarbonate and features a water-sealed zipper, making it resistant to liquid and dirt. The exterior has a front zip pocket and two side pockets, and the interior consists of one large chamber with two additional pockets and a built-in laptop sleeve. The straps and backside are padded for extra support and comfort. To carry by hand, just shorten the shoulder straps and use the top tote handles. Einfach!
