Hi Rusty,

Here is a link to a page where Doug writes about Stearns' Inflatable Sportsman's Vest from Eagle Enterprises which not only has lots of pockets for gear, but also provides 22.5lbs. of buoyancy via CO2 cartridge or inflation tube. (Here is the larger picture.)

It's not quite what pilots wear, and it's not really a PFD (Personal Flotation Device), but it looks like it was obviously made for fishing (with that lure patch), and would probably be useful for any number of outdoor activities.

Stay safe,
J.T.
