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 Basin or 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.

The best

If you’re looking for a good Shedhunting pack that can hold some weight, pack some horns, and camp gear.. look no further.
Only thing I wish was if there was the ability to access the frame for bungees. This pack is the most versatile and best pack I’ve ever used.

Main frame with the V5000. By far a superior product by eberlestock when it comes to frame packs in today’s market. I am excited to be using this set up for the CO first rifle elk hunt, it’s super comfortable with it being loaded down with about 56lbs of gear.

Used for hauling a pelican cased medkit in the field. Added the batwings and ended up with the most modular rig I have ever used.

Mainframe and batwing pack

Haven't had a chance to use this yet but very comfortable and well built frame. Super light weight, the batwing pack is good for hydration pack or to keep game bags and knives in. Can't wait till September to try this out on a moose hunt!

Awesomeness

This pack is so versatile. I have used it for packing out meat, packing in Bear bait and hauling all my gear around while hunting. I strap a small pack on it while hunting that way I have the frame with me in case I need it. Light weight and super durable!! There is a lot of options as well to make it whatever you like.
