      THE HOLY GRAIL OF

      MODULAR PACK SYSTEMS

      The F1 Mainframe represents what is arguably the greatest innovation in modern pack making, the holy grail of a great modular pack system. But unlike any other pack system, with this load bearing workhorse as a base, you can build a true ultra-light pack simply by adding one of our J2DB Dry Bags. 


      The F1 is one of the primary base-platforms for the EMOD -- the Eberlestock Modular System, and it works with an ever-growing number of complimentary accessories. Add components of your choice, and the Mainframe can function as a freight pack, day pack, or all-around utility pack. For hunting, it transforms to a meat hauler within seconds

          Everything I wanted in one pack!

          I love this pack! I love the price of this pack! I really like that I can configure the main frame to whatever I am doing. If it's shed hunting then I take the main pack off and go with the bat wings. If I am going in overnight then I take everything and drop the main pack at camp when I am hunting. No more packing around an extra large gear pack with nothing in it! Great idea Eberlestock!

          Better than expected!

          I did not realize the pack both zips into the main frame as well as uses tie downs. It is a great system to expand what you carry.
