F1 tall mainframe

I have the f1 tall mainframe . I found the fit to be perfect did have to adjust the shoulder harness to the actual frame itself but once customized it is perfect(I'm 6foot 230 pounds). I run the dual batwing and rifle scabbard. Just used it for whitetail season did everything I wanted/needed it to do flawlessly. Initial setup wasn't hard at all YouTube videos do wonders. I use a henry 30-30 lever action no scope. Once your gear and straps are tight it holds the gun in place very well doesn't slide across the back. Very easy to draw from standing position. Overall pack does everything I want and more it was very comfortable loaded up and walking up and down the rocky terrain we have. It is pricey but worth every penny!

F1 Mainframe is Incredible!

When you invest a good amount of $$ for a product like the Mainframe, you expect high performance as well. For me, the Mainframe exceeded even my high expectations! I am so happy I got this. On a side note, I am 6’-0” and 200# and the Standard size frame fit me perfectly (just like the guy in the picture in the magazines) when I extended it to the tallest setting. The extension was really user friendly as well. I purchased the Batwings and Large Accessory Pouch and they were good investments as well. Overall, I’m extremely happy and packed out a mature whitetail deer no problem! Awesome pack! Only minor negative comment - the “Sternum Strap” came off probably the 5th use. Hopefully Eberlestock is reading this and will send me a new one.
