[quote=Seriously though, I assume its a cpr mask compressed enough to be unobtrusive but robust enough to live in your pocket with keys and change etc. that would be good. where did you get it from?=[/QUOTE]

The CPR mask is a 2"x 1 1/2" x 1/4" thick pouch I got mine from the trainer when I did my last first aid at work course but I an sure they would be avilable from the Red Cross web site.
