The BAM Cabine series are ultra small and compact-- they were designed around the idea of carrying it on to the cabin of a plane. These cases are tiny! The outside of the case features anti-shock textured ABS shells, with rings for the 2 included neoprene anti-slip backpack straps with security hooks. Closed via 3 soft-touch latches and secured with the included key. The inside of the case is made of injected high density polyurethane foam.
