    Abstract: A flotation device to be worn for water activities includes first and second buoyant end portions and a clamping member that may be multi-sectional. The clamping member passes from an abdominal region of a user between the user's legs to a back region of a user and is used to move the buoyant portions toward and away from each other to clamp the flotation device to and unclamp the flotation device from the abdominal and back regions of a user's trunk. Preferably, the flotation device includes one or two connectors for connecting the flotation device to a tether so that a user of the flotation device can swim in place when wearing the flotation device.
