Ortlieb D-Fender backpack for touring riders The waterproof、 dustproof D-Fender backpack is constructed from extremely wear and crease-resistant material to Ortlieb’s tough quality standards. Its 38 litres of storage space are filled via a waterproof zip closure. Because the zipper faces your back、 you can put the D-Fender down and open it without getting grime on the carrying surface. Ergonomically positioned foam pads on the D-Fender channel air flow across your back for comfort. Padded shoulder straps with an adjustable chest strap ensure good load distribution. The D-Fender is an excellent choice for use as a luggage roll because there are no loose straps flapping about and the carrying handle makes handling easier. Six D-rings are attached to the D-Fender and are ideal for securing the rucksack to your motorbike.
