I had the boys (and siblings) in my Cub Scout den create survival kits. We went through the Hug-a-Tree information that I could find on the web.

My kids (ages 9 & 10) wear them whenever we are out and about. In addition to this they are "usually" carrying a 1 qt wide-mouth Nalgene bottle with them. I recently switch them from the Lexan bottles to the translucent white HDPE (poly) bottles because of the controversy over Lexan, though I still use the Lexan bottles.

We start with a small cheap fanny pack:

<>whistle on a coiled wrist strap from orientaltrading.com; since then I replaced the cheap whistles with WindStorm whistles

<>two 33 gallon 2 MIL orange garbage bags from spectrumtrashbags.com (with prior instructions/practice on how to tear a face hole)

<>Princeton Tec keychain light from campmor.com fastened to whistle wrist band

<>Orange bandana from wholesaleforveryone.com

<>We've recently added small lockblade Gerber LST knives to my kid's kits, though they are a bit too young to make much use of them if lost.

<>I've recently been thinking about adding a folded quart sized Ziplock bag and some Aquapur tablets - I think they are old enough to use them

Soon I'll probably add a bigger knife, a mini Bic lighter, and DEET lotion, but quite not yet

Quite often they are carrying FRS radios while "exploring" nearby woods, just to allow us to keep in touch.

Eventually my plan is to give each kid one of Doug's PSP's with a few additional bits added. I've already bought one for my son who will be starting in Boy Scouts next spring.

Much more importantly, I have ground into their minds the understanding that we need to know where they are going, and as soon as they realize they are lost (defined as not sure where they are or where they should go) that they need to STOP, look for a place where they can most easily be seen (found) and wait to be found. I've also emphasized that they must be careful not to fall in water or get wet.
