I used my DR PSPs as a foundation for a larger PSP. I removed the contents from the original container and use a small Alkosak to carry all the contents (minus the cord, instructions, paper and pencil,) and add a AMK Heatsheet, DR Freedom Light, Prep Razor, gerber formula bags, benadryl, spectra cord and Micropur tablets. The kit is bigger then the DR PSP, but easily fits in any pants back pocket or BDU pocket.
