We've redesigned our deluxe cello bag and haven't left out a single bell or whistle. The deluxe cello bags are made of a highly protective 1680 Ballistic Nylon with thick 25mm padding. It includes accessory pockets, bow holder, and a comfortable backpack strap that can be completely tucked away into its own pocket. The backpack straps are designed with a clip harness to minimize movement while worn.
