Got a question about what backpack I’m using. It started out as a Stone Glacier R3 5900 with a xcurve frame (2018), but has become somewhat of a frankenstein by now.
The original SG setup has served me well, and I love the bags simplicity and easy access. The frame however gets a bit uncomfortable with the heaviest loads (and tends to «barrel»).
Last year I put the bag on a eberlestock f1 frame, but it wasn’t a real improvement. This year I’ve been using the SG bag on an exo k4 frame, and it is - by far - the best setup I’ve tried. It really shines with the heavy loads.
Putting the SG bag on the k4 frame is mostly plug and play, reusing most of the buckles and straps (with some minor adjustments like switching male/female buckles). I also had to add two extra buckles at the top. I prefer using the R3 bag without lid. I’ve also transferred the meat shelf from the SG to the exo.
