The shape and dimensions of the SUSTAIN Backpack have been carefully chosen to fit the most popular modern synthesizers and drum machines. Each SUSTAIN Backpack ships with 4 padded dividers with velcro, so you can customize the interior layout and provide excellent protection for each of your machines.

The premium backpack straps are comfortable and spacious. And there's also an extra-thick handle, for the times when you prefer carrying it in your hand. We've carefully chosen the highest quality zippers, durable exterior materials, and a super-soft interior lining.

With 3/4" of dense foam padding surrounding the entire interior, and rigid molded plastic panels incorporated into the exterior body structure, your gear will survive the rigors of the road.

Since no live show is complete without cables, there is an extra-large zippered pocket, which can also hold a laptop if you're so inclined. We've also included a large piece of flat foam that can attach to the interior lid wherever you'd like extra padding above sensitive knobs or keys.
