>>2390505I have a Eberlestock Vapor 5000 with the F1 frame. It's a light pack but not ultra-light by any means, but I do like having a little more durability and the modularity the frame brings. Is definitely an excellent pack system but I am about to grab one from Kifaru in the future to try out. Very happy with their Kifaru slick bag so I'm expecting potentially a better pack from them.
Side note: Also if you get the slick bag from Kifaru and you are over 6ft, the regular length will work fine for you. The long is ridiculously long like 8ft in length so it will become unnecessary fabric weight for most people. But damn it's comfy.
