The EVAC Systems Pre-Rig Rescue Backpack is a specialized deployment system that allows technical rescue operators to transport a fully pre-rigged mechanical advantage system and up to 300 feet of static rope, enabling sub-minute operational readiness at the anchor point.

The Pre-Rig Backpack is engineered around a single readiness principle: the system should be built before the team arrives on scene. By pre-staging a complete raising or lowering system such as a Z-rig or RPM inside the pack at the station, operators eliminate the on-scene assembly bottleneck that traditionally costs multiple minutes under stress. Integrated Velcro loops and retention straps secure every hardware component including pulleys, carabiners, and descent control devices in their exact rigged configuration, ensuring tangle-free extraction and immediate deployment upon arrival.

The pack's extended vertical chassis accommodates up to 300 feet of 1/2-inch (12.5mm) static rescue rope, flaked during pre-staging to guarantee clean, twist-free payout in the field. A semi-stayed internal frame manages the substantial weight of a fully loaded system, ranging from 30 to 50 pounds, by transferring load to the operator's hips rather than the shoulders. The narrow, low-profile chassis minimizes snag hazards in confined spaces, dense brush, and narrow canyons, keeping the load centered for stable movement across technical terrain.

Constructed from heavy-duty Cordura Nylon and manufactured in the USA to Berry Compliant standards, the Pre-Rig Backpack serves Rapid Intervention Teams, Mountain and Wilderness SAR operations, confined space rescue, and industrial standby rescue environments. Speed of deployment in technical rescue is a clinical variable, and this system is built to compress a multi-step field assembly process into a single, fluid extraction action from pack to operational in under 60 seconds.
