This large-sized street pack is designed for medics who carry more. Boxy and compact, with ergonomic hauling, its unique design keeps the shoulder straps off the ground when accessing contents. Internal cells stack neatly and securely in many different configurations. This pack accommodates the First Aid QuickRoll Intubation Kit, Circulatory Kit, and Remedy Kit, as well as the stackable Cellular System. The aluminum track creates a bomb-proof secure point for the shoulder straps that allows for comfortable transport of most emergency medical equipment. Up to 4 of the Generation 3 standard cells will fit inside as this is the largest size of the EMS backpacks that are designed to use the Cellular System. Red.
