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

Comfortable with heavy loads

Best fitting harness I've used bar none. When adjust right the pack feels better than any heavy load should feel.

Great Frame

After back surgeries, I got away from running, and found that 'rucking' is actually good exercise and not hard on the spine (promotes good posture, and makes you walk softly). I paired the F1 with 2 batwing pouches...put a weather proof sandbag in each bat wing pouch, strapped them down. It has been a great fit, the weight does not move around at all, makes it VERY stable, and comfortable to walk with / train with. For me it was about burning calories and keeping in shape, but I can definitely see this working to train for that big hunt that is coming up. Thanks Eberle Staff !!! Love your products.
