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 700 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 F1 Mainframe™ is fully adjustable and completely user configurable with endless combinations.


  • 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.


  • 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.

Well worth the money

Super comfy and versatile. Makes hanging my sets easy, hiking or packing out.

Kyle C. (Utah)
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.

F1 Mainframe

Initially ordered the tall, (6’1.5” 215lbs 19” torso for comparison) and it felt like majority of the weight was sitting on my tailbone even with the pack full adjusted up. The regular out of the packaged fit perfect for my torso. Weight sat right in the small of my back. Tall seems more for the tall tall folk. Recommend the regular if you’re right on the line like myself.

Excellent quality and comfortable

Seems extremely durable and comfortable. I can’t wait to put it and myself to the test on an upcoming moose hunt this fall. Combined it with the bat wings and the 7200 dry bag. Boatloads of room!
