This All-Terrain Mobile First Aid Cart is empty so that you can fill it up from scratch to meet your exact needs, and get it ready to roll quickly to any medical emergency. This rolling Trauma First Aid Bag has a unique crush-resistant exoskeletal frame that offers an integrated seat and gear platform that can carry up to 300 pounds of additional gear. The external aluminum roll cage frame provides more packing space and durable protection from falling debris for your trauma first aid supplies. (Supplies and internal organization systems sold separately.)
