Customers say the frame is extremely comfortable, lightweight, and often mention the modularity and adjustability.
Highly rated for:Comfort Under Load, Modularity, Adjustability
With the Modframe™, we’ve taken everything that made the Mainframe great and rebuilt it from the ground up. This is more than an upgrade; it’s a next-generation hunting platform.
The Modframe™ is a purpose-built foundation for serious alpine hunters who demand performance, durability, and flexibility in their pack systems. Built leaner, stronger, and more customizable than ever before, it offers new levels of fit, comfort, and load control, and it’s fully compatible with every pack, bag, and accessory in the Hunt EMOD™ system.
When it’s time to pack out, detach your pack, strap your game bags into the load-panel, and reattach your pack. This keeps the heaviest weight close to your back and reduces fatigue.
Revamped Suspension System:
Modframe ™ features a reimagined shoulder and hip-belt harness with over 50% more padding than our previous design. It wraps the shoulders and lower back in form-fitting comfort, while extra-tall load lifters keep weight off your traps and over your center of gravity, allowing you to go farther without wearing down.
Integrated Load Panel:
At the heart of Modframe™ is a low-profile load panel that replaces the traditional L-frame shelf. This keeps weight closer to your center of gravity, improving posture, energy efficiency, and control during heavy pack-outs.
Supreme Durability:
The Modframe™ is engineered for years of hard use in alpine environments. The frame itself is built from aircraft-grade aluminum and polycarbonate, efficiently blending strength and flexibility. Its interior panel flexes laterally with your stride, allowing the pack to move with you, while the vertical frame structure keeps gear centered and tight to your back.

Know Before You Buy
Customers praised this highly comfortable, modular pack frame for exceptional weight distribution and versatility. Many compared it favorably to premium brands at a fraction of the cost. Reviews highlight its ability to carry 80-100+ lbs comfortably during mountain hunts. Some concerns noted: squeaking straps, durability issues, and waist belt sizing limitations.
This was my first season backpack hunting with my Eberlestock Modframe. I was fortunate enough to tag a nice muley on the first day of the Washington general season, but as the only guy in the group with a pack on me at the kill-site, I ended up hauling all four quarters back to camp. The Modframe carried the load like a champ. It's got enough straps on it that the load stays close and tight to your back and the robust waist-belt helps transfer the load to your hips. I definitely could not have done it without the Modframe.
The only upgrade I plan to make is a couple of Batwings to help provide a little more side-to-side stability, and to avoid having to carry the backstraps and grinder meat in my main pack strapped on top of the quarters where the load tends to sag a bit.
Overall, a great product that I highly recommend!
Just packed out my bull elk this weekend, mod frame, bat wings, and lid make a killer combo with. Couple boned out game bags!
i use this frame for the first time in my life bud i can only say what a perfect frame. i was so happy with this. give me all i needed in mountain hunting
Very impressed with this pack. I put about 12 miles on it during a horseback hunt, and it was easily the most comfortable pack I’ve ever used. I’ve packed around 50 lbs in it so far with two large Batwings, a lid, and my bow, and it carried the weight extremely well. Super comfortable and plenty of room for everything I needed.
Just what I was looking for.. Hopefully in the next couple weeks I will get to pack a deer out using this system. Over the past few years ive been using a pack that I was unable to remove the pack and when you have to make a second trip in it was horrible that I had to take the pack and not just the frame. This past weekend I was able to use the pack hiking with camera gear and a tripod. The mod frame was comfortable and the brooks pack did the job. I look forward to putting the miles on wearing this pack. I plan on doing a full review on my YouTube channel in the near future.
This is a mixed review. First, the pack did what I needed it to do during a five-day hunt. However, I’m disappointed with its durability and no longer have confidence that it will hold up to the use I expect from an Eberlestock pack.
During the hunt, the pack saw relatively little abuse. At some point, a tear developed on the bottom, although I’m not sure exactly when or how it happened. The pack was not exposed to anything particularly sharp. Its primary use was going from my house to my truck, to my ATV, to my back, and into the tent. I also made a point of not setting it down on sharp rocks or branches.
For a pack at this price point, and from a company whose products I’ve historically trusted for their durability, this is disappointing.
I’ll likely return to my Skycrane II with the Little Brother and Super Spike Duffle, which I’ve used for roughly ten years. Those pieces have been put through the wringer, and aside from some blood stains, they still look and function like new.
It seems that some durability may have been sacrificed in the move toward lighter-weight, more modern packs. While I may continue using the Modframe for hiking or camping, I don’t plan to rely on it for my hunts.
Overall, the pack performed well during my five-day hunt, but the early tear has significantly reduced my confidence in its long-term durability.
My personal complaints, I like to carry my 45 OWB and it seems that I will have to find another place to carry due to the massive hip belt straps.
The other engineering feature I can’t grasp is why the packs zip up to the frame and not down on the frame? Yeah you have a bungy that holds it, but it still pulls down and offers mediocre support for the heavy stuff up high.
Outside of the 2 things, the pack becomes awesome.
Haven't hauled anything heavy but this pack is of the best quality and comfortable also bought bat wings and the just one pack and that pack is awesome as well don't overlook it!!
Super comfortable. I love how easy it is to convert to meat hauling mode. Also love the modularity. The ability to switch out the bags is awesome. I have the brooks 3500 for day trips and the 7000 for extended hunts. 10 out of 10 would recommend!
I bought this pack for a Bighorn sheep hunt in CA. I was not able to use it much before the hunt (injury) and was concerned how it will perform. I wanted to get some miles on it loaded, but that didn’t happen. I’ve used eberlestock products before, but mainly EDC stuff. Was very happy with the performance of the pack! The load was well balanced with the way the pack is designed. Highly recommend this bag.
I got the Modframe in October, 2 days before they went on their Black Friday Sale. I asked Eberlestock if I could get credited for the price difference and they actually hooked me up! I love this company now...and I ended up spending more than that on their gear after I got the credit.
The Modframe itself is everything I was hoping for. I don't hunt at the moment, but I've been rucking and hiking with heavy weight trying to get back into shape. I started looking for alternatives to my Alice ruck after I had 75lbs in it and it rubbed a hole in my back that is now a scar. With the Modframe I usually carry 75-90lbs up a 1000 foot mountain in less than a half mile. This pack almost makes 90lbs seem light. Although I did try 125lbs 2 weeks ago and that was a little too heavy for me, but the Modframe handled it with ease. I don't know what they will ever do to improve it because it so comfortable to carry heavy weight. Putting bags on and taking them off is so easy it is almost unreal. I was even putting my 55-60lb kids in the brooks 7000 and swinging them around for a durability test. At first I was a little worried because the bags are so light, but me and the boys gained confidence in them very quickly and they wore me out and were having a blast.
I can't say enough good things about this frame and bag, they are everything that I was hoping for and more. I know that it will carry as much weight as my spine can handle and it will do this in comfort and not rub holes into my skin.
Used the Modframe Pack with the Batwings to pack out a whitetail buck over 1.5 miles in PA public land. Once you have the pack adjusted properly to fit your personal frame it is unbeatable. Packing out a buck that far is rough in general but I will never drag again!
Helped a buddy pack out his first ever elk using this mod frame. Handled the trek and the weight well. Comfortable to wear for hours. Also washed stains out well.
The Modframe is a truly versatile pack with endless options to mount storage and equipment and can even be used to add weight and train for your next hunt. Very strong out of well made materials, light and very comfortable. Completely satisfied
To start, the MODFRAME pack is the best pack I have ever used. I have used the Eberlestock Justone pack for several years now and the balance and weight distribution of a full pack compared to other brands shuts them down. But like all great things alot of the padding needed an upgrade but decided to get a better upgrade with the new Eberlestock MODFRAME. Being out in Hawaii we take gathering seriously and the product does not disappoint. I packed a large spike and a doe and it was the best packout I ever experienced. That day I also harvested a large bodied buck and the MODFRAME pack made it feel easy. In the past I got to sample friends high-end, super expensive packs that start with the letter "K", and they were great, but im declaring right now that the MODFRAME pack is superior compared to the ones I ever tried. Great product, Great company to say the least
Pack is amazing and very happy with all of your products. One thing that was very disappointing was that less than a week after I purchased it went on sale for Amazon prime days……. Would have saved money on the pack and the shipping….. frustrating because I actually spoke to a customer service rep and they said it wouldn’t be on sale until Black Friday, which my hunt is this coming week so I had to just go for it. Live and learn I guess. Should have been more prepared.
Everything you could want. Can't see it ever letting me down and I definitely see what all the rave was about
I just packed out half an elk and it worked perfect!
good frame
Definitely one of the more comfortable frames I’ve used. I have had stone glacier, kifaru, mystery ranch, and a couple other brands. This frame is on par with kifaru in terms of comfortability at a fraction of the cost.
Comfortable, fitting,
Can this pack fit a gun scabbard on the back of it? Also I was planning to attach my bandit to this would that work?
You can run the Bolt Action Scabbard to this frame, but the Bandit will not automatically attach. You may be able to get creative with different straps, but out of the box, the Bandit will not work.

Really love these pouches, the elastic pocket is super handy
I’m new to every day carrying and this brand/bag was recommended to me. I’m very happy with this bag with the Molle 1x3 attached. Extremely comfortable and great material. I absolutely love the color.
this thing packs down super well
Great Product. I trust Eberlestock products completely. Best and most modular bino pack system made.
Best pack frame for serious hunters, period.
Ordered these just to have, can’t get them from other pack companies I have used.
Great for smaller stuff.
I had an exo with hip pockets. They sat to high and seemed to be in the way. I now have a brute 4500 added the pouches and they are perfect I didn’t hit my hands on them when hiking there just the right size.
This bag is awesome and does everything I need it to do. Plenty of space and pockets. Strap placement, structural rigidity and construction are great.
It work amazing for what I needed it for. Allowed me to carry some work equipment off of a hill top in one go, instead of making several trips. Carry the weight exceptionally well.
This is the pack I’ve been waiting for my whole life. I saddle hunt whitetails and get all my saddle gear including camera equipment without a problem. And it doesn’t even feel heavy. Elk hunting is a dream with it as well. Only thing I wish they’d do, is add molle attachments to the sides of the pack and in other areas for accessories.
Great product. I currently use these for wet dirty laundry inside my duffel bag. They work perfectly and don’t hold smell or moisture. Highly recommend.
Only bag needed for range day. Holds everything and keeps it organized. Added pouches on the outside to hold mags.
Great size bag and was nice for a 4 day training event. Held everything I needed and kept things well organized.
