          Redefined The Greatest Pack

          Bought a main frame many years ago, it has been through all kinds of adventures. On this last adventure I got lost with only a hand full of trail mix and no food or water for 10 days. I knew which way was east but I was so deep in the mountains, and there were so many mountain ranges and valleys to cross. That climbing up and down them and pushing through thick bushes became too much, there was a point I could only hike for around 5 minutes before collapsing. That’s when I knew I had to drop all my gear, eventually I got back to the highway.

          Once I got home the time came to get a new pack, I didn’t have to think about which pack I was going to get. It was going to be another Main frame set up, and I really like how the new hip belt pulls to the center to tighten, it makes a big difference when you have the belt loaded with pouches, and the way the harness and belt are set up it makes the load feel lighter.

          Mainframe

          Can’t say enough about the mainframe. I love the versatility and ease of which to change out bags and accessories depending on need. The frame is extremely durable and has held up to all the punishment I have put it through. The shelf makes hauling meat a breeze and comfortable. I liked it so much that I bought another for my daughter.

          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.
