      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

          Great Product

          I got Batwings and a mainframe and am very impressed. Solid construction, light, and comfortable. I recommend and will be buying a 50 liter pack next!

          F1 mainframe, batwings and vapor 2500

          I had never used any of the Eberlestock packs but after receiving the f1 mainframe, batwings and vapor 2500 I loaded it up…I was blown away by how comfortable it was and can’t wait to use it on my upcoming elk hunt!

          Typical Eberlestock Quality...

          ...which is excellent. Combined it with a vapor 5000 and a dry bag rifle scabbard. Love the modular options. Will be using it for backpacking this summer and hunting this fall. Will likely add a multi-lid to finish my setup.
          Would love to see something along the lines of a zip on tomohawk style pack become available for this frame.
          This is my 4th eberlestock pack. I have yet to see another company do such a good job at creating products that meets the needs of hunters/shooters/backcountry explorers.

          Haven’t used it for elk hunting yet but have taken it out rucking in preparation for some backcountry turkey hunts coming up and wow it’s awesome! Super durable and fits great!

          Good product but poor for the customer

          Pack frame appears to be of good quality… only issue being if I waited 30 days I could have saved almost $200 on the frame and vapor pack. Seems like it is just a crazy mark up and I would recommend everyone wait until march if you were to ever order from here so you don’t get ripped off.

          F1 Rocks

          Recently purchased F1 frame + Batwings + bolt action scabbard and love how well they work. The fit is perfect and I have been winter trekking with the pack loaded down many times. Love the modularity and the fact the frame allows the pack to stand vertical when I take it off. Thanks Eberlestock !

          Great fit I'm 5ft 10 inches 175 lbs and got a regular. I added the batwings and dry bag for the 2500 size for now. Looks like I'll have plenty of room for a 3 to 5 day trip!

          F1 mainframe

          This pack frame is well beyond my expectations. Super comfy even after loading it down with 40lbs and hiking 4-5mi. Would highly recommend this pack to anyone

          Not bad but need improvements!

          All the point of an external frame pack consists in attaching stuff to the frame. And in f 1 there s no access to the frame except for the bottom. I thing a good idea would be to expose the frame in 3points just in case if. Someone like me would want to have more attachment points or use much longer straps. Overall the pack is pretty good

          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.
