I am sorta with Steelheader 69 on this one, if you are in a place where you think you might need a life jacket, probably should be a good one. I see a lot of people wearing those SOS spenders and it just does not look like something I would bet my life on. Extrasport makes some models that are pretty slick and not real bulkey.. I read sometime ago that like 75 % of men that are pulled out of the water after drowning have their fly open ( peeing out of a boat at speed # 1 cause of drowning for men).. I can see how that might be true. Closest I ever came was wading in the Salmon river with a pair of seal dry rubber waders on. Slipped and they filled up in 1 second and took me to the bottom. If my buddy would not have been with me I think I would have drowned.

Those auto inflate ones you guys are talking about. They work off a sensor that detects water??? I don't think I have ever seen those. What if it was raining out ??? must be more to it than that ??
