This is a duffel bag-shaped dry bag with carrying handles. The large opening makes it easy to load and unload items. It offers extremely high waterproof performance, is robust, abrasion-resistant, and has excellent weather resistance and durability. Attaching it to a motorcycle is as simple as placing the bag on the seat and securing it with the included shock cords. The hooks at the end of the shock cords are made of resin, so they won't scratch the frame. It also comes with a shoulder strap.
