IRR™ system utilizes a strong, yet light weight specialty material to construct the internal support ring. It helps the soft fabric air dispersion system retain inflated look without static pressure. The system is extremely light weight, and adds very little extra installation time. The patent pending sew-in pocket construction makes the system very flexible and easy to wash. Additional tension cables at the end of each straight section ensure fabric between rings is kept round and taut when deflated.
