The F1 Mainframe represents what is arguably the most durable and versatile pack frame on the market. The F1 features a tubular aluminum frame to provide its unparalleled strength while maintaining ultra-light capabilities. Tested to hold more than 700 lbs., this ultra rugged frame utilizes YKK zippers to allow the attachment of a variety of packs and accessories to fit any backcountry hunt. Experience premium comfort unlike the rigid frames of the past, as the Mainframe was designed to fit ergonomically correct, distributing the weight properly across the hips and shoulders.

ULTRALIGHT SETUPS

  • The Vapor 2500, 5000, or 7500c.i. for any length adventure with ultra-light considerations. 
  • 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 and make packing out meat simple.

MID-RANGE SETUPS

  • Pair with the Super Spike Duffel or 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. Allows for top-loading or front-loading access and use the Mainframe when it is time for some heavy lifting.

EXPEDITIONARY SETUPS

  • For a 5-10 hunt, use the new Vapor 7500. Pack all of your gear into the backcountry and when you reach camp and drop your gear, the Vapor series with collapse nicely against your frame to allow you to day hunt out of your camp.

Best frame yet

I purchased the F1 frame to carry my climbing sticks and gear for saddle hunting. This frame is awesome. Weight is distributed evenly and very easy to adjust. Molle webbing all over for more packs. Best frame I’ve gotten.

F1 frame pack

Just received my pack last week . Wore out the other day to test out ... awesome ! Glad to support a free state manufacturing company! Spend the money for a well built pack and support a free state company . Vote with your dollar . I love the modularity of this pack system . Waiting for “batwing” pack accessory to come back in stock to add to my personal system . Am recommending to my hunting buddies.

F1 Mainframe and Vapor 2500 bag

I have been training with the pack on short hikes, 4 miles. Seems like a great pack weighing it down with water jugs. The only suggestion is that the downward adjustability of the shoulder harness be made three levels lower to get to the fit you describe in your fitting video. Otherwise waiting for your availability of the wider longer padded belt, the scabbard, some ties, and scabbard cover that you are running behind on production. Hope you get it all in before the fall. very happy with what I have so far and think the wider longer padded belt will be a great addition.
