I strongly agree with
@newfydog on going with PFDs made specifically for kayaking.
I've owned around 50 different PFDs between different water sports and growing bodies of my children over the years. My kayak vest design looks much like the one in his link, and it's my favorite by far.
Kayak vests are designed to allow for greatest range of motion with least resistance while paddling in a windmill like motion. Range of motion needed is similar to casting a fishing lure.
I also like the comfort and range of motion on self inflating PFDs that my pal provides when fishing from his sled on the Columbia. He is a guide and uses the Mustang self inflating PFDs.
My only complaint about his particular Mustang PFDs is that the material is constantly plucking at my beard hairs and occasionally head hair too. It's like it grabs onto it and doesn't want to let go. It's pretty annoying to have a few hairs pulled everytime a guy turns his head. Sometimes it goes beyond annoying and actually pulls hard enough hurt a little.
I'm not sure the hair pulling thing is a problem for everyone. Could be my hair and beard are just the right diameter and length to catch in the heavy duty coarse cordura weave of that particular PFD.
That's been my experience for the two cents it's probably worth.
