Compact Profile, Full Mission Capability

The PiggyBack Pack was engineered as a modular hydration and sustainment solution for field use. It attaches directly to your existing chest rig harness for a single-unit setup, or connects to any ruck or plate carrier with top and bottom tie-ins. Use it as a beavertail, day pack, hydration pouch, or comms carrier—the PiggyBack adapts without excess weight or footprint.

Drop your larger pack at base camp and keep moving with just the gear you need. Whether you’re covering distance, running drills, or setting up an overland cache, this pack punches far above its size.
