      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.

      Excellent

      I bought this because I venture further then you would want to drag a deer and needed a quality pack frame. I’ve only used it for training hikes so far. (40 lbs max) but it’s performed flawlessly. It’s really easy to get my weight strapped down and it’s rock solid. If you’ve got a load, no matter the shape, that needs to be hauled this is the pack that can do it.

      Everything I wanted in one pack!

      I love this pack! I love the price of this pack! I really like that I can configure the main frame to whatever I am doing. If it's shed hunting then I take the main pack off and go with the bat wings. If I am going in overnight then I take everything and drop the main pack at camp when I am hunting. No more packing around an extra large gear pack with nothing in it! Great idea Eberlestock!
