Good sea kayaking choice
I bought the Kokatat Bahia Tour PFD for sea kayaking. It is very comfortable and seems to fit better (i.e., does not ride up over my head) than other brands I have tried. I particularly like the pockets on the front and the clip on the bottom (if you clip the bottom, it is very easy to zip up). Although I do not participate in any white water kayaking, I think it would be good for that activity as well.
