The Gator Case GK-LT-25W Laptop/MIDI Controller Bag is a combination Backpack/Rolling bag designed to carry most 25 note controllers and a laptop. An expandable top allows up to a 37 note controller to fit within the padded interior and inserts that have been designed to protect your gear. Exterior zippered pockets provide additional organization and storage for interfaces, cables, and other recording accessories. To transport your gear, take advantage of the removable, retractable wheels and handle to pull along behind you. Or, remove the handle and take advantage of the backpack straps that can also be tucked into an exterior pocket when not in use. The rugged nylon construction protects your gear from the wear and tear of travel, dual zips ensure an extra level of security if you choose to take advantage of a small lock, and a built-in identification pocket allows you to put your information on your bag in case of accidental separation.
