      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.

      Great Pack

      Light, comfortable, and customizable. The system makes carry heavy loads easier and is very durable.

      Excellent modularity

      This is the best frame produced if modularity is your focus. Nothing else produced can touch it in that regard.

      Haven’t used it in the field but with the new bat wings it’s A sweet set up I can’t wait to try for elk and deer season

      The best

      If you’re looking for a good Shedhunting pack that can hold some weight, pack some horns, and camp gear.. look no further.
      Only thing I wish was if there was the ability to access the frame for bungees. This pack is the most versatile and best pack I’ve ever used.

      Main frame

      Main frame with the V5000. By far a superior product by eberlestock when it comes to frame packs in today’s market. I am excited to be using this set up for the CO first rifle elk hunt, it’s super comfortable with it being loaded down with about 56lbs of gear.

      Used for hauling a pelican cased medkit in the field. Added the batwings and ended up with the most modular rig I have ever used.
