The frame allowed me to jury rig the pack to make it fit my 6'2"body. I had used the frameless Gunslinger for over five years with minimal comfort. I believe it is suitable for someone under 5'10." I am glad I made the decision to purchase the frame rather than discard it and try another brand, In other words, the frame saved the Gunslinger!"
I bought it to attach the ButtBucket to, and it works as intended.
Switched out the frame on my gunslinger pack, to use for heavier carries, would recommend to anyone looking for a different curve, it fit my back perfectly.
Provides great support and structure to my G2 Gunslinger II for loading and while carrying. Also makes for a great anchor point for attaching gear externally underneath the main compartment, such as a backpacking tent.
