The Ortlieb Saddle Bag Large is a compact and handy storage option which fits to your saddle rails and seat post. They all come in either Black, Blue, Green or Red. Providing room for equipment, snacks, innertubes and tools for long day tours. It tucks in nicely under the saddle, and often functions as protector on bikes without fenders. The additional fixation with Velcro around the seat post provides firm and vibration-free mounting. Reflective detailed trim is on either side and the backward facing part of the saddle bag which gives you great visibility on the road to other road users and pedestrians. The content you choose to put into the saddle bag will be dry and safe due to its 100% waterproof roll closure features buckles and D-rings for locking the bag.
