I dont really trust the inflatable PFD's(to many varialbles to go wrong, bad Co2 cylider, finding the release cord), But they are better than nothing.

I Bought a stearns life jacket. I found the one that was the lightest and offered the most range of motion. When I'm wearing it I hardly know its on even in the summer time it is never to warm to wear. It is a little bulky in front but I've gotten used to it. the only change I would make is to eliminate the buckles and just use the zipper. the loose ends of the straps can get in the way when flyfishing.

check out the homer picture in the "wild fish pic" thread... he's wearing it!
