      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.

      Did not disappoint.

      Great modularity, lightweight, and well built. Whether you’re going on a day hike or an extended stay the F1 Mainframe has you covered from their long line of modular bags and accessories.

      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.
