An armband is a piece of material worn around the arm. They may be worn for pure ornamentation, or to mark the wearer as belonging to group, or as insignia having a certain rank, status, office or role, or being in a particular state or condition. Sprung armbands, known as sleeve garters, have been used by men to keep overlong sleeves from dropping over the hands and thereby interfering with their use. Armbands may also refer to inflatable armbands used to assist flotation for swimmers or for use with sphygmomanometers, in which case they are generally referred to as cuffs.
