I have two similar models. One is made by Self Reliance Products (
www.srp-usa.net) and includes the basic stuff you might forget (knots, navigation by sun and stars, ground to air signals, traps, firestarting, CPR). The other one I got at EMS and has real basic first aid info. Both are 22" by 22". The survival one is a dull orange and the first aid one is crimson. I keep both in my day pack in a zip lock next to the FAK.
Are they worth the money? If I had the forethought before buying them I would have gone to a craft store and picked up a paint pen and a yard of dayglo cloth and made my own. Even if it lasted only a dozen washings it would be cheaper.
