The new inflatable line of life jackets are easy to put on, wear and take off.
If it only saves one life that makes it worth while taking the time to wear one.
If it saves your life that is priceless.
We always wore inflatable vests when flying the heavy water bombers and also Gen Tex Helmets.
I never had to use the life vests but the Gen Tex sure made flying them so much more comfortable and at the end of the day we were far less tired because they protected out skulls from the noise and shock waves the props made.
