      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.

      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

          First hunt packed out the head and front shoulder

          Pack was more than expected. Had the mainframe with two bat wings and got an elk the first hunt I took it out. Packed out the head and one front shoulder without use of any rope. Very handy

          Fantastic Setup

          I've done a couple trips with the f1 and Vapor 5k now and the pack was fantastic! One was hauling 6 gallons of water 4 miles to my buddies hunting spot, another carring 7 days worth of food plus everything I needed for the hunt and the last was packing half a deer plus all of my gear out. I highly recommend the pack.

          Best frame I’ve owned!

          Well thought out yet simplified design is great for endless configurations. Lightweight and very sturdy.

          My husband definitely needed this upgrade! He is 6’2” and I was happy to find this size for him. It was comfortable for his long hike and hunt!

          F1 Mainframe

          I recently purchased the F1 mainframe with the bat wings, 2500 cu. in. bag and rifle scabbard. I changed from a Lanner 5400. The fit of the F1 was far better and I like the modularity of the bags. I used it on a mule deer hunt in Wa. and it was great packing out. I just recently returned from an elk hunt in Montana and it was a joy to wear on long hikes. The rifle scabbard was a bit to get used to but once I readjusted it and got it set right it was great. I believe the F1 system to be a superior hunting pack. I would recommend the F1 to anyone who hunts.

          F1 Mainframe. Best pack I’ve used in a while.

          The F1 with the Vapor 2500 is a lightweight, incredibly versatile pack that has become a favorite of mine. Picked one up with the rifle scabbard running between the frame and the Vapor. I couldn’t be happier with this setup. Very comfortable, the frame is very adjustable and makes fitting easy. I would recommend this setup to anyone looking for a good, all around multipurpose pack.

          Very modular for many needs.

          HOW HUNTERS RUN THEIR F1 MAINFRAME

          ULTRALIGHT SETUPS

          • The Vapor 2500, 5000, or 7500c.i. for any length adventure with ultra-light considerations

          • 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 Super 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 new Vapor 5000 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

          • For a 5-10 day hunt, use the new Vapor 7500. Pack all of your gear into the backcountry and when you reach camp and drop your gear, the Vapor series with collapse nicely against your frame to allow you to day hunt out of your camp.
