Cruiseliner Inner Duffels are stitched to shape so they fit easily into the compartment of the hard bags. The generous size conforms to the inside cavity with room to spare. These well-constructed duffels are made from 600 denier polyester with a waterproof coating. Two-way zippers allows easy access inside the bags. These features, along with the sturdy nylon web handles, make it easy to remove and carry your items without removing the saddlebags from the bike.
