      ULTRALIGHT SETUPS

      • Choose the Vapor™ 25005000, 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.

      Mainframe

      Very pleased with this purchase. Not only was the shipping and delivery very quick but this new mainframe system is perfect for what I need. A robust and sturdy frame to haul the heaviest loads of meat and or gear without sacrificing a bulky frame system and comfort.

      Flexible and Customizable

      Vapor is unbelievable. Lightweight and creates great flexibility. The additional pocket on the front has a flexible material which makes it easy to get items when the bag is compressed.

      Incredible

      The ultimate sustainment pack, truly. Very well built, well designed, & well thought out. Coupled with the vapor 2500, (2) batwings, top lid & scabbard, I can last quite a while out there if I had to. More than satisfied.

      Great pack!

      I love my main frame! It's modularity makes it great for quickly changing what my needs are at any moment. The pack reminds me of my time in the military using the Alice frame, but this pack is so much easier to disassemble.
