The primary base platform for the EMOD™ system with a constantly growing number of accessories. Build it up to be a multi-day expedition pack, or go in light so you can come out heavy.

Tested to hold more than 1300 lbs., this ultra-rugged frame utilizes top of the line zippers to allow the attachment of a variety of packs and accessories to fit any backcountry hunt. The Mainframe™ is fully adjustable and completely user configurable with endless combinations. 

ULTRALIGHT SETUPS

      • Use the Vapor 2500 or 5000 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.
      • The Bolt Action Scabbard and EMOD Lid are great options to carry your rifle and gear handsfree.

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.

Good solid frame. It was definitely an improvement over the FIBLE frame I was issued, and I even managed to get the FIBLE mainpack sack to work with the frame, even if it wasn't designed to fit.

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.
