Pack with the mainframe II was perfect for 8 days in the hills of Hells Canyon for spring bear. Will add the large batwing when they come back in stock to have a better day pack system. I clipped the assault pack in for day pack to the mainframe for now and worked fine.

Well made equipment. Surprisingly collapsible, if you can only afford 1 bag, get this one. Lid being included, is awesome, fits more than you'd want to carry. Front zipper opens to main compartment, no more digging from the top! Saving for another bag!!!

Needed something larger than the 3500 that I already have for longer packs in. Quality is great, currently training with it on the off season with sand bags and it holds up fine. More than enough room for a week long backcountry hunt. I’m 6’5” so all of my gear is larger than normal and I have no problem fitting everything.

I recently purchased the Eberlestock Brooks 7000 with the ModFrame system for hunting and backpacking. While I haven’t taken it on a full multi-day hunt or packed out meat yet, I’ve used it on multiple weighted hikes and a day hunt, and first impressions have been very positive.
I’ve done a couple 40-lb weighted hikes using the meat shelf with a sandbag, along with one day hunt running just the ModFrame and EMOD lid. The pack was comfortable under load and felt well balanced. On a steep climb that required some rock scrambling, the pack stayed stable and never felt like it pulled me off my center of gravity.
The ModFrame + EMOD system is clean, quiet, and easy to configure. I like that I can run it fully expanded for a 5+ day hunt, compress it for a 1–2 day setup, or strip it down to just the frame and lid for short hunts or moving to a glassing position. For my day hunt, the EMOD lid attached cleanly to the frame and held everything I needed. I was also able to strap my bow over the lid using the included straps, and ran a MOLLE water bottle attachment on the waist belt without issue.
Access is excellent. Being able to get into the pack from both the top and the front horseshoe zipper makes organizing and accessing gear much easier.
Build quality on both the frame and bag feels solid. Stitching, zippers, and materials all seem well done. The two areas I’m curious about long term are the front stretch pocket on the bag and the stretch pocket on the lid, as the material is fairly thin. I also noticed the zipper attachment on the ModFrame hangs slightly below the bottom of the frame and bag—not a dealbreaker, just something I noticed (I just tuck the "zipper tails" under my pack for a cleaner look).
Overall, the Brooks 7000 has been comfortable, stable, and versatile so far. It seems best suited for multi-day backcountry hunting, and I’m looking forward to putting more miles and weight on it this season.

I've put my 9 year old and 6 year old in it separately and swung them around. I think this bag is great and I'm glad I went with the 7000. It's a great size and incredibly light.

I like how this pack is made. It fits seamlessly with the emod system. I like that with this system, I can easily modify it to fit different activities. The Brooks 7000 is so well made and spacious. It is so well thought out and designed even down to the smallest details.

Very well made! Brilliant product. You will not be dissapointed.
