Everyone in my family has a CamelBack with PSK items that they wear when they go hiking or camping. They are a work in process. This Christmas I am going to upgrade everyone to the hooded HD Space Blanket and the County Comm Metal Match. Right now some have trash bags and BSA Hot Sparks.

I like to try different PSK items and see what works best. If an item is good then I get everyone in the family one. There are 6 of us. So far everyone has:
Storm whistle
Glass 2”x3” signal mirror
Base plate compass
First-Aid kit with selected supplies like the Burn-Jel
BSA First-Aid card
CMG Infinity Ultra AA LED
BSA Hot Spark
Neckerchief
And other stuff
