      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

          Only pack I will ever need.

          The Eberlestock F1Mainframe provides endless expandability options to take me from Whitetail hunting in the Allegheny’s to Elk hunting in the Rocky Mountains and beyond.

          Meat hauling pack

          I love that this pack is made for taller people. I am 6'6" tall and it fits my torso super great. I haven't healed anything with it yet except for a couple of neices and my son but it seems to keep the weight where it should be!

          Good stuff

          Only a few miles on the frame so far. I have used it with the vapor 5000, zip on dry bag, and zip on bay wings. Have not carried out an animal on it yet, but have been archery hunting steep country in the south San Juan’s of Colorado and it’s been a real back saver.

          I love it. I’m am not kidding I freaking love this frame.

          Very Comfortable

          Great frame that is extremely comfortable. I've used it on four trips now, all over 7 miles with about 40 lbs, and it's paired with the Vapor 5000 and bolt action scabbard. I haven't packed any meat yet, just scouting while carrying a rifle if I see a bear, but I have no reason to doubt it will function just fine. The rubber on the bottom part of the frame must have had something rubbing on it and it's worn off a little, but that's probably my fault as I didn't have the pack secure enough.

          65 yr old Elk hunter

          Will be using the main frame pack in a few weeks on my Wyoming Elk hunt. Hooked on back country hunting with packs and I’m sure I will love this pack. I will write or update this review after my hunt. This is my second pack from Eberlestock and I’ve always been partial to frame packs so when this came out I finally decided to get it. I’m selling my J34 to my buddies son at a great price it’s a great pack but I know I will love this main frame better and the versatility of it.

          An Absolute Workhorse of a pack!

          Just hauled out 265 lbs of elk in one 1.65 mile trip between two Eberlestock packs - my F1 mainframe handled 3 elk quarters in one trip and not a stitch popped or seam tear!!! The renegade fit the last quarter, backstraps, loins, and trim..Amazing Quality!

          Amazing gear

          I love mainframe and all the accessories. I hunt public land which means lots of hiking. I should’ve made the switch to Eberlestock a long time ago.

          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.
