I believe the most important issue concerning flotation devices for paddle sports is maneuverability. If I can’t get a full paddle stroke because I am impeded by my vest, then I consider my PFD purchase trivial. I don’t have that problem with my Hobie Inflatable PFD. There are other inflatables out there but they do not have back straps which keep the flotation tubes square on your chest. Nor do they have the easy self-inflating system such as Hobie’s T-handle pull. My jacket gives me the range of motion, and the comfort I want when I am kayaking.
