Personally I've never worn a stone glacier or a KUIU. I do however, have a good friend who owned a KUIU and had some major troubles with it and sent it back for a refund. I have heard several negative reviews about the KUIU pack frame, which I am sure will get worked out over time but for now I would stay away from KUIU if it was me. I have noticed this site is predominately a Kifaru centered market it seems like. Probably for good reason as they make great packs. Personally I wear a Mystery Ranch and I think you would have to shoot me to get me to wear something else as it stands right now.

I would stay away from KUIU until the issues with their frame get worked out in the future.
