I know inflatable life vest have been beat to death on here, I ALWAYS wear a life vest, but in the summer they are HOT. I have a ski vest , but not USCG approved.There is the belt flotation system that requires manual activation. How often do you test the inflatable flotation system? Yearly, every 6 months or just look at the clear view window, how easy do they activate. Little water, sumursion or some other accident. An activation system is about $27.00 bucks. Not a lot to save a life. Anyone have any thoughts or comments. Thanks.....crappie1133
