The black shirt or the blue one? Two pairs of shoes or three? Can’t decide? You don’t have to. Our largest waterproof bike bags offer enough space for everything that matters to you. The Back Roller XL bike bag is made of durable, waterproof, and abrasion-resistant material and, with 70 liters per pair, offers almost twice as much storage space as the classic Back Roller. It’s also the first ORTLIEB Back-Roller with an additional mesh front pocket. While this isn’t waterproof, it’s incredibly practical with an extra 4 liters of capacity per bag, perfect for water bottles, sunscreen, or wet items. The proven roll-top closure keeps the contents of the inner bag clean and dry at all times. Thanks to the ingenious Quick-Lock system with self-closing hooks, the bags can be attached to virtually any bike rack in a single step. We manufacture the bag at our factory in Heilsbronn. The design is repairable and built to last.
