Inflatable vest (Buoy Boy)
Also: Buoy Boy, automatic vest
Inflatable vests are light and small but have to be inflated by mouth or cartridge. Anfibio offers an inflatable vest called the Buoy Boy.
They can be an option for calm water and ultralight trips. In whitewater or the cold we recommend a foam vest, because it floats without you doing anything.
