A wrist mounted inflatable floatation device to provide temporary floatation support for a swimmer, boater, wader, or other person who is in the water. A wrist mounted floatation device is conveniently worn when someone is in the water or on a boat. It is attached to the wrist by a wrist strap which is adjusted for a snug fit around wrists of a variety of sizes. Mounted on said wrist strap is a deflated and folded inflatable bladder. Also mounted on said wrist strap are means for inflating said inflatable bladder when need for a floatation device presents itself to a user. The means can be high-tech gas storage devices, such as carbon nanotubes or chemicals, that when triggered produce a chemical reaction to produce either a gas or a gas filled polymer material, or a simple inflation tube and check valve, which allows a user to manually inflate the bladder. The bladder is attached to the wrist strap by a cord. When inflated, the bladder detaches from the wrist but remains attached to the wrist by the cord. The bladder will ordinarily be made of some highly reflective material or be colored with a readily visible color such as yellow or orange. The bladder is sized to be large enough to provide floatation support for an ordinary person. It is not designed for use with a person who is unconscious or otherwise unable to grip and use the bladder to support themselves in water. Because of its convenient size and wrist mounting, it is more likely to be utilized than cumbersome life jackets or life vests.
