      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

          An excellent frame

          If I am to mention a single backside, it's that the metal frame is hidden inside fabric and you cannot use it directly to strap things to it, but it's just a minor flaw of a great carrying system.

          Nice Pack

          Would be nice to have 4 anchor points on each side. Maybe 1 top and bottom also. Otherwise nice pack! Waiting on batwings to add.

          Best Frame Pack Ever!

          Haven’t had a chance to use it hunting but have been using for the MTNTOUGH 45-70 Fitness program to start getting ready for next year’s Colorado hunting trip. Extremely comfortable and the customizability of this pack is next to none!

          Looks good and fits good. It seems comfortable and light weight. Hopefully I will get a chance to test it out soon.

          Very versatile

          To be used as a back-country hauler for my portable capstan winch, and primarily as a rifle pack for regular ski trips patroling the property. Excellent quality, fit and finish.

          Great pack for a female hunter

          Female hunting gear is difficult to come by. I purchased this bag as a gift for a female hunter after an extensive conversation with the customer service team at eberlestock. This pack fit my girlfriend who stands at 5'6" and 130lbs at best. I must point out that I don't own one of these myself and I was envious of how comfortable she was hauling gear in Southern Arizona.

          Good quality very comfortable haven’t used in the field yet but no question it will do what it’s made for
