I am not sure if Frost River consulted with a geologist on this. I can imagine several features that would make this pack an actual geologist pack.
-hammer loop for rock hammer
-very small pockets for hand lens and acid
-field book pocket
an actual geologist
While I’ve had the pack for only a short while, I can say that the construction, design, and materials are top notch. The main compartment holds more than enough for a day trip and the outer pockets are perfect for a PFAK or food/fire kits. I hike and day trip frequently and expect many years of service from this pack.
The only complaint I have about this pack is that it really should have had some kind of flexible support frame inside of it to give it shape. When you put it on even with stuff in it it's just sags down like a shapeless saggy full diaper. I bought an insert for it and it helped a little. Other than that the leather and canvas quality are top notch.
As à Indiana Jones fan , I needed this bag for my cosplay and it is perfect
