The F1 Mainframe Pack is what a great modular pack system is all about. It's one of the primary base-platforms in the Eberlestock® Modular System (EMOD) lineup, giving it true mix-and-match versatility. Add complementary accessories of your choice (not included), and the Mainframe can function as a freight pack, day pack, or all-around utility pack. Build a true ultra-light pack simply by adding on an Eberlestock J-Type Zip-On Dry Bag (not included). For hunting, it transforms into a meat hauler within seconds.
