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.

F1 Mainframe

I have been looking at getting a new hunting pack for some time. I have spent far to much time researching, comparing, reading reviews etc than I care to admit. All my due diligence led me to the Eberlestock F1-Mainframe along with its many e-mod components. I ordered the Vapor 5000 pack and Vapor 2500 packs along with rifle scabbard and a few other accessories to go along with the F1 frame. I took the pack out in the field for the first time this past weekend on an elk hunt and could not have been more happy with it. I LOVE the versatility of the F1 e-mod system. I can easily convert the pack to a day pack with the Vaper 2500 or to an extended, multi day hunt with the Vapor 5000 pack. I absolutely love that about this pack system. Its many packs in one and suites all of my needs as an avid hunter. Could not be happier with my purchase.

HD tactical gear

Best of the best and top of the line, only downside is their quantities are always low or out of stock. Wished there was an overabundance of their gear especially in dry earth color. I now have a bunch of mismatched mission essential gear because it's all they had

It is great have not hauled anything,but grand kids I was going to order the bat wings,but instead I will just use another pack with compression straps,because when I ordered it,it had free shipping and 10% off when you used the promo codes,but it did not give me either one
