Watch the in-depth pack overview video below.

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

CUSTOMIZE YOUR PACK WITH COMPATIBLE ADD-ONS

ULTRALIGHT SETUPS

  • The Transformer is ideal for day or overnight hunt trips. Stay organized but still have a frame to haul meat.
  • Use 2 Batwings when you plan to go in light and come out heavy. Stay quick, light and mobile with the Batwings. They are intuitive and make packing out meat simple.

MID-RANGE SETUPS

  • Pair with the Spike Duffel or Dry Bag with Batwings for a 2-4 day hunt. Pack all of your gear into the backcountry and when you reach camp and drop your gear, unzip the duffel or dry bag and hunt in your ultralight Batwing setup.
  • If you like the organization and function of a backpack, the Little Big Top is the ideal choice for a 2-5 day trip. Allows for top-loading or front-loading access and use the Mainframe when it is time for some heavy lifting.

EXPEDITIONARY SETUPS

  • The Big Top is ideal for those who want to get out and stay out for extended 5-10 backcountry stays.
  • For a 5-10 hunt, use the Dry Bag and Little Big Top. Pack all of your gear into the backcountry and when you reach camp and drop your gear, unzip the dry back and hunt in your compact Little Big Top setup.

Compression strap issues

Why don't you guys let all of your loyal customers know that the compression straps are too short to go around the batwings and either; meat, dry bag, or super spike duffel? I have the batwings and a dry bag and there is no possible way to snap the buckles together. I know that you sell accessory straps, but unfortunately, they have the newer buckle system or whatever and are not compatible with this. I found some chinese 4 foot accessory straps on Amazon that were compatible with mainframe buckles, so I'm fine, but this is misleading at the least.
