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.

Mainframe

Can’t say enough about the mainframe. I love the versatility and ease of which to change out bags and accessories depending on need. The frame is extremely durable and has held up to all the punishment I have put it through. The shelf makes hauling meat a breeze and comfortable. I liked it so much that I bought another for my daughter.

Truly does it all

I usually use Eberlestock bags at work, so instead of trying the competition, Kuiu, Stone Glacier, etc I gave eberlestock a shot. Not only does this frame come with options. It’s damn durable, I took a nasty spill while glassing off a cliff face. The frame didn’t snap or break after taking a large fall over multiple boulders - Yes, I was still wearing the frame (along with a 2500 series eberlestock bag (Vapor I think it’s called?) regardless, it didn’t bend or break. I still load it up with lots of weight and it performs like new everytime. At seriously a fraction of the cost of its competitors. I won’t say it saved my life, but I will say it saved my hunt. - that’s good enough for me.

Mainframe Replacement

I cannot be more satisfied with my new Mainframe or Eberlestock’s customer service. The first Mainframe pack that Eberlestock sent me had a defective attachment strap that I did not discover until I was in the field. I was able to jury rig the pack and still transport meat out of the field. I continued to use the pack for the rest of the hunting trip. It is by far the most comfortable pack I have ever used.
After analyzing the defect, Eberlestock replaced the defective pack for me promptly. Again, I am 100% satisfied!

Well Designed Pack Frame

I packed my first elk with this set up and it worked very well. Easy to set up, quarters stay put, and tough enough to hold all the weight I could handle. The batwings are a nice setup: once you’re packing I zipped them off and left them with the first load. Easy and fast, this pack made getting out of the bear woods with a pile of meat a breeze. I use a small dry bag loaded with my essentials as an additional part of the pack, if I’ve already tagged out and I’m going with another hunter who has his own knife, gamebags, etc I can just leave my dry bag in the truck to save weight. This pack will be perfect for antler hunting, I’m looking forward to simplicity and utility.
