The Odyssey Innovative Design BR312 Bag-style Rack Case (Black) is made of tough 800 denier ballistic nylon with fully padded 1/2" foam interior, and a carpet-covered hard shell insert. It is made to transport rackable gear up to three spaces (5.25") and 12" high. It features chrome-plated, lockable zippers that can be locked together for added security on the front and rear, allowing access without removing the interior shell. There is a roomy zippered pocket for storage of all the essentials such as mics and cables, etc. The rack bag allows removal of the interior hard shell from the padded bag so it can stack firmly on top of another without the bag getting in the way. The black carpet-covered interior shell is 'studio furniture friendly'---there are no rubber feet or metal edges to damage or mark surfaces. It includes a shoulder strap, along with a small bag of rack screws and washers.
