The first one I bought was put in a compartment and I didn't wear it at all and one day much later when I was going with someone else and intended to use it I found it had inflated sometime. I rearmed it and started using it all the time. I really like it in the winter time over heavy clothing because it is not noticed at all. It did inflate one day I hadn't been wearing it and had left it lying in the bottom of the boat on a hot summer day.
I really like mine.
“There is no difference between communism and socialism, except in the means of achieving the same ultimate end: communism proposes to enslave men by force, socialism—by vote. It is merely the difference between murder and suicide.” Ayn Rand
