The main PSP web site is at

The discussion of add-ins is contained in a link on that same main page, down in the second have. It is the
POCKET SURVIVAL PAK Bonus! Survival Information While I've played around with lots of different kits, I've lately been simplifying them and now pretty much carry the recommended items from Doug's Bonus info.
I use a Ritter PSP into which I've slid:
<> a mini-Bic lighter,
<> a couple of Micropur tablets,
<> and Doug's Freedom light.
On top of that I carry:
<> either the fullsize Rittergrip or the mini,
<> a poncho or a Tacoma Mountain Rescue Storm Shelter (from REI.com) depending on the forecast/duration,
<> a 1 quart wide-mouth Nalgene bottle w/ water,
<> a hankerchief or bandanna,
<> a charged up cell phone,
<> a first aid kit (either a larger one if with a group, or a slightly supplimented Adventure Medical Kits Pocket Medic if just me).
I'll usually also carry a fullsize compass with a WindStorm whislte attached to the lanyard, a map of the area printed off my PC, a Leatherman Charge Ti, and a small bottle of DEET.
