The Sunbounce system consists of an aluminum frame that can be easily assembled and combined with different reflecting, light-reducing, or light-absorbing screens. This frame set includes the lightweight, stable, collapsible anodized aluminum 12x12' frame, 2 grip heads for attaching the butterfly to stands (not included), bungee "snakes" for attaching the screen to the frame, and a carrying bag for the whole kit. The frame holds the screen taut, giving you consistent shading and diffusion, with no "hot" or "cold" spots.
