The Responder 72 Backpack is the pack you need when the call comes in and nothing can be left behind. Engineered for EMS, fire, and law enforcement personnel, the 50-liter capacity Responder Backpack comes with two vertical and four horizontal internal dividers to keep critical contents from shifting. The removeable dividers are fully adjustable to fit the load. Secure an oxygen cylinder (sizes D and Jumbo D) inside the main compartment with the non-slip, quick-release strap. If one O2 cylinder won't cut it, an internal slip pocket holds a second cylinder. Everything inside is protected by reinforced closed-cell foam panel construction. The light-colored lining adds contrast for low-light use. The full clamshell opening, with quick-pull tabs and optional color-coded snaps, speeds access when time is critical. Dual internal zipper pockets, an internal slip pocket with elastic bands and a clear divider keep smaller, quick-grab items staged for duty. On the outside, a large zippered pocket in front, two large zippered pockets on the sides, and a dual-access zippered pocket on top hold additional life-saving essentials. Padded shoulder straps and a removable sternum strap keep the pack where you want it when you're on the move. An aluminum frame and HDPE board back panel provide support for heavy loads, while grab handles on the top and front maximize carry options. The wipe-down-friendly exterior simplifies cleanup. Reflective strips on the shoulder straps and front panel magnify visibility. Fully compatible with our Responder Med Pouches, the Responder 72 Backpack is the top choice when you need to haul a full load of gear.
