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.

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.

One frame to rule them all

I finally got fed up with the cheap backpack straps my climbing stand came with and treated myself to this tank of a frame pack. First time loading up all my gear it was laughable that it took me that much suffering to finally pull the trigger on this pack. Wish I would’ve bought this thing YEARS ago. (Picture is first time strapping my climbing stand to the pack. I wedge my bandit pack in there and clip it on with a carabiner and I’m right as rain).

This pack out performed any pack I have purchased and used over the years from other name brands. I and 6’4” and weight a solid 300lbs. I added the padded shoulder straps and large padded belt for my set up. I was able to walk mile after mile without your typical pack fatigue on this years Elk hunt. The pack performed flawlessly and provided the customization everyone wants. I would highly recommend this to anyone!!

Like it alot

Big fan, I’ll be honest it doesn’t quite carry quite as comfortable as some of the others that I have, but when it comes to being able to take the ruck off the back and just utilize the rifle scabbard for glassing points, and the bat wings, I have found it to be the set up that I have. I had a piece of strong tree branch bust one of the waist belt retainer straps on the hip belt, which was a bit of a bummer seeing that it was brand new but……..OFW.

The Mainframe is a very well designed pack. Without the other EMOD components/options, this packet can and does stand on its own.

I found the shoulder straps and waistband to be more comfortable than other packs I have owned or used. All the adjustments (shoulder straps, distance between shoulder straps & waistband; waistband) allow you to adjust the pack to you and your preferences. I could wear this pack all day without feeling like I needed to stop and take it off. Even when I had it loaded down with an entire deer, I felt like I could have hike for hours longer without needing to stop because the pack was uncomfortable.

As a day-hunt setup, I paired the pack with two Batwings v2 and the Scabbard. The Batwings provided enough space and room for more. I used them to carry extras layers, hydration system, game bags, field dressing kit, emergency items, and food. They have plenty of small pocket to place those little items for easy retrieval. I was a little hesitant about the scabbard; namely the ability to retrieve and return the rifle without taking the pack off. These worries quickly disappeared after using it in the field. I found it easy to pull my rifle and return it with ease and not cause a ruckus when doing so. The Scabbard was also a life saver when both hands were need during steep ascent and descents. Not having to hand carry or sling carry my rifle was a feature/ability I didn’t realize is a must.

I will be adding other pack options to my EMOD for longer hunts or hikes.
