This 100% waterproof travel bag has all the advantages of an easy to use dry bag: its flexible and variable packing volume adjusts to any situation and takes all the gear for travelling and sports. The roll closure with stiffener bar has its roots in stuff sack technology. It fits perfectly into bike trailers and sizes 24 L or 31 L can be combined with ORTLIEB Back- and Sport-Rollers Plus and Classic on the rack for bike touring. This robust multi-talent bag is also good on motorcycles. Comfortably carried with adjustable padded shoulder strap and carrying handles.
