Seems to be a very well built system. Looking forward to using it soon. Only thing I wished the bag had were some MOLLE straps on the lid as well as on the bag

Carries weight well especially on the modframe. Only used it for a two night scouting trip but it will carry everything you need and then some.

I am going to use this on my frame with the mainframe 2. EVERYONE is moving to optimizing less weight, but that comes at a price. Sure you can eliminate the metal frame and incorporate a fabric load shelf. Try hauling a metal bear bait barrel with a fabric shelf. My old Kelty Cache Hauler served me well for many years, but the metal bars that hinge the shelf get in the way of hauling a barrel. I am really glad that Eberlestock did not throw the baby out to change the bathwater, completely eliminating the mainframe with the mod frame. This is another reason why I trust Eberlestock so much. You can fanboy or fangirl your favorite brand based on their logo, but whatever brand you use... they are all basically making the same archetype of gear. Eberlestock is a company you can trust. They supply to multiple different industries which gives them lots of feedback on how components, straps, binders, zippers, velcro strap concealment devices work, work well, and need to be placed on their products.

I paired it with the Modframe and couldn’t be happier. Navigation, medical, saw and hatchet, food, clothing, hot tent and stove, bedding - the pack holds it all.

Plus, and maybe most importantly, the Brooks lets me be the beast of burden when my kid comes along. Nothing takes the fun out of hiking and camping like weight on the shoulders and hips over long distances. I suffer that so my kid can glide along, but without the 7k that might not be possible.

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.
