I have not tried doing that yet, but I can see how it might possibly work. I'm not as savvy when it comes to converting bags-to-frame as other Rokslide users, but I will let you know what I come up with.I really dig the detailed comparison between the packs. Would you be able to see if the Exo bag would be able to be mounted to the Stone Glacier frame? I really like the layout of the Exo bag, but I'm a little leery of the top horizontal frame piece, especially since I might be using the pack while I'm wearing a helmet.
Did you ever take a look at the outdoorsman packs?I just released a video comparing Kifaru, Exo Mtn Gear, and Stone Glacier. This is part one in which I simply just go over the bag and frame, and put them under a quick load to get an idea of how they will perform this fall hunting season.
Kifaru 44 Mag + Duplex Lite Frame
Exo Mtn Gear K3 4800 + K3 Frame
Stone Glacier Sky 5900 + Xcurve Frame
It's a long video because I wanted to cover as much as I could with each pack system. Peep the description of the video to see timestamps to help navigate you through the video if you don't have the time to (or just don't want to) watch it in full.
There are some minor issues throughout the video like wrong terminology, so forgive me for being a little dumb here and there. Let me know what you guys think!
