When you think of waterproof bike bags, what name comes to mind? Ortlieb, of course. Ever since company founder Hartmut Ortlieb got soaked on bike tour of southern England in 1981, this German company has specialized in keeping bike tourists protected from the rain. The Back Roller Classic panniers are one of Ortliebs most iconic products. Durable polyester fabric and welded seams makes them a long-lasting touring companion, while the waterproof roll closure ensures safe and dry storage of equipment and food. With its QL-1 mounting system, it is quick and easy to take it on and off your rear bike rack. A shoulder strap provides carrying comfort away from the bike.
