      HOW HUNTERS RUN THEIR F1 MAINFRAME

      Eberlestock F1 Mainframe

      ULTRALIGHT SETUPS

      • Choose the Vapor™ 2500, 5000, or 7500 for any adventure with ultralight, multi-day performance.

      • 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 to use and make packing out meat simple.

      MID-RANGE SETUPS

      • Pair the Super Spike Duffel™ or the Zip-In 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. This pack allows for top-loading or front-loading access and then can separate from the Mainframe for game bag carriage when it’s 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 off your kit, the Vapor series will collapse neatly against your F1 Mainframe so you can day hunt out of your camp.

      I love the versatility of the pack frame. The ability to customize the frame for what kind of hunts you are doing from a day hike to a week out in the back country. The pack frame is very comfortable and it is easily adjusted to properly fit.

      I haven’t had a chance to try it out yet. I just got it last week but from what I can tell it fits great and seems like it will handle a lot of weight. judging from other products of bought from Eberlestock stock, it will do just fine.

      F1 Frame

      Fit and finish is what you would expect from Eberlestock. Second bag from Eberlestock and I can’t wait to get it out this Elk season

      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 !
