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.

really comfortable even when put weight on to it
There wasn’t a single thing I am disappointed with. My only recommendation is to add molle panels on the side of the Force chest rig lije what us on the Fierce and the binoharness
So far so good, frame is light weight and comfortable after adjusting. After strapping weight onto it and hiking up and down hills very little fatigue.
All day comfort with minimal excess features. Everything is easy while being convenient and reliable.
Love it so far.. also have only used 3 times so not enough to give a review but if it turns out anything like my f1 frame pack I'll love it forever
I like the modularity of the product
Best mod system ive seen

Read Full Privacy PolicyJust for reference: Dress shirt, neck 15.5, sleeves 32/33, chest 42”, waist 32”; I am not tall, 5’8”, 180; Large Alturas fits great in the sleeves, drops right at the waist with just the correct amount of coverage on the back, waist is great without even having to tighten it and just a little snug across the chest. Definitely could fit a light base layer under it. Medium made me look like Tommy Boy. Excited to put it to work.
I went on 4 different hunts last year using a chest rig I got from hill people gear. It did do the job, but it’s no built for binos and a range finder. So I got this guy and the range finder case in just a few weeks ago. I can’t wait to use them on some upcoming hunts I have! They have their own place, nothing random gear in the same pocket getting in the way. I also love how quiet they are to use.
I bought the medium last year just before an antelope hunt. Worked great for the back straps and loins. So I got the large this year for an upcoming elk hunt. Just for some odds and ends. It’s well built, feels good in your hands, doesn’t feel cheap. Can’t wait to use them both this year.
I haven’t used it just yet. I have multiple Eberlestock bags it’ll fit. But last year on an elk hunt I only had a trash bag when it started raining. It worked but of course it wasn’t the best option. This products feels great and fits all my bags. I have another elk hunt coming up and can’t wait to use it if I need it!
So far so good, can't wait to use it this hunting season,
I love it. Its perfect!!
Great fanny pack. Perfect fit for my 2k11. Nice pockets for my cards.
I purchased another pack from Eberlestock as my EDC. It carries my laptop and other work-related items. The pack was designed to carry coms, but it works well for my needs. I did need to get creative when it came to carry my pistol. I've found a solution that works for me. Quality as always, perfect size and comfortable to carry.
I replaced a much more expensive Briggs & Riley messenger bag with the Fade Sling, and I honestly prefer it. It has a clean, modern design, feels well-made, and offers just the right amount of space and organization for everything I carry day-to-day.
It is comfortable, lightweight, and works equally well for business, travel, or casual use. The quality is excellent for the price, and I never feel like I am giving anything up compared with the more expensive bag.
So far, I am loving everything I buy from Eberlestock. The Fade Sling is another great product and an easy recommendation. Only wish I purchased it before the Briggs&Reilly.
The Fade Sling has been a welcome addition to my EDC.
Came from a badland xr pro. Love the more compact modular design with the bear spray and range finer pouch perfect set up for me
I am a LDPR shooter. I needed a bag that could haul everything I need to the range. Its fairly discreet and I was able to set up the bottom to hold lots of extra goodies as well. Real nioce quality and easy to carry comfortably even when fully loaded. Nice piece of kit.
Comfortable addition to the Switchblade. Highly recommend.
This thing is amazing! It is a great size and holds ALOT! The internal organization is superb! It makes me want to carry more stuff than I actually need. Built like a tank! I expect nothing less from eberlestock! If you are in the market, I would definitely recommend!
Its a perfect bag for my camera gear and accessories. Its well made and the oversized zipper pulls are a plus. The depth of the bag i great for keeping small items from falling out
