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.

Anticipation !!

My review title is called “Anticipation” because I haven’t yet used in the field; and that is why I did not give it a five star rating yet. I’ll be using it for the first time in an upcoming elk hunt out west in October.

Mainframe utility!

The mainframe is easy to set up. With all the accessories, you can stack, move, and change the system in very little time. Overall quality is high. Do yourself a favor and get the additional buckles with the EMOD lid. Will have longer review after elk packout.

Most versatile bag I’ve ever owned

I got the Vapor 5000 and 2 bat wings to put on my mainframe. Just with these 2 sets of gear there are so many ways to configure them on my mainframe. Super excited to use this during hunting season!

40 lbs easy

Now I did get it for hunting but it's not hunting season yet but part of preparing is doing hikes here in wonderful utah. Well half way my 5 year old decided it was to much walking. Now she had a wonderful seat and then strapped to the frame as well. She made it half a mile before she passed out. So a 40 lb kid strapped to the frame with 10 lbs of other things thus thing felt great. Fits snug in the shoulders and high on the hips. Comfy and great airflow. Kiddo didn't complain much either. Here is to putting in all the extra miles.
