I carry a Ritter PSP (and a growing number of other items) in a Spec Ops Mini Pocket Organizer. This is for easy pocket transfers. It rides in a cargo pocket, or Max Proteus if no cargo pockets are available <img src="/images/graemlins/smile.gif" alt="" />

Actually, I carry another Spec Ops mini with EDC items in the cargo pocket on the other side...Space Pen, Rite in Rain pad, nail clippers, flash drive, etc.

I still want to build kits in an Altoids tin, tobacco tin and a Witz See It Safe...just for fun <img src="/images/graemlins/grin.gif" alt="" />
