Probably most may not agree with post but something to think about...
I have found an inflatable to be life saving, at the least...
I was on the West Fork of the Bitterroot near the confluence with the East Fork and had the foothold I had give way. If it was not for the auto-inflate of my vest I would of been in great amount of trouble, or worse. Would a foam vest done the same? Sure - if had worn it. But would of I worn a foam vest is the real question. Probably not...
I have been in a float tube on Lenice where I was tossed out of it due to winds and waves. Should I have been out there? An emphatic NO! But I was. If it was not for my inflatable, I would not be here talking about it. Would a foam vest be better - probably... But glad I had an inflatable...
Will more of us wear an inflatable or a foam vest? If we are not wearing a foam vest, which many of us do not, because it is providing comfort to our 'buns', wouldn't an inflatable vest be better? I think so because to put on a vest AFTER an issue requiring a vest there may not be sufficient time or, under some circumstances, where we could not put it on, aka an emergency, a vest located in the boat providing soft comfort for the 'buns' little resolution of when one actually needs it.
Do I believe a foam vest is Best (if worn)? Absolutely! But if was no vest worn or an inflatable - I would choose an inflatable. For sure!
