<font size="3" face="georgia,palatino">I have had a SOS since 2000... Put it on when I get out of the truck, take it off when I climb back in. Just a reminder though. I always keep mine in the truck. I used to have two and I would leaveone in the boat. Went to put it on and it had auto-inflated in a compartment, not a pretty picture. Moisture and auto-inflates do not mix. Also, they will not fully inflate in cold water and given the extra weight of winter clothing it could make for a disaster. Always wear a full size conventional when winter fishing, if for no other reason then it is a lot warmer.</font>
