The Conterra Responder IV is the largest and most organized response bag of the Responder series. It is very similar to the Responder III (#10 coil zippers, SI-Tex fluid proof fabric, etc) though the main compartment is long enough to fit an oxygen bottle and will accept the Oxygen Caddy Insert. The Responder IV is built with side pockets on both sides (which are long enough to fit c-collars) as well as pockets on both ends. The inside of the bag is lined with velcro in order to support any of the MOS organizing accessories.
Features:
A great BLS pack
Made of indestrubtible ballistics nylon
SI-tex fabric protects against bodily fluids and water
