Recently got one of these… just got to get my new Denali Llama out there to try it now !

http://www.packrafting-store.de/Safety/Anfibio-Buoy-Boy::499.html?language=en
It packs down very small and is pretty light weight at 310g for the smaller size (blue) AND 365g for the larger (red) one. The optional crotch strap adding 30g. It has 2 inflation chambers each with a dedicated spring loaded mouth valve.
It does not conform to any designated Standards and is not an accredited or certified PFD.
No afiliation etc just a customer passing on knowledge of new gear out there :)
