The Sunbounce system consists of an aluminum frame that can be easily assembled and combined with different reflecting, light-reducing, or light-absorbing screens. The Medium Screen Saver Bag for Sun-Scrim from Sunbounce is a duffle bag designed to safely transport and store your Sun-Scrim screens (not included) up to 12x12'. Plastic windows allow you to see which screens are in the bag. There's also a small holder for insertable labels in the bottom. The bag measures 20 x 14" (52 x 36 cm) flat and weighs 0.57 lb (262 gr) when empty.
