Inflatable armbands, are devices to help a wearer float in water and learn to swim. Inflatable armbands are typically cylindrical inflatable plastic bands that are inflated and worn on the upper arm. When the wearer is in water, the air inside the armbands provides buoyancy on account of its far lower density than the water. Although often thought of as a child's flotation device, armbands are also available in adult sizes. Although inflatable armbands are popular among small children, swimming experts caution against using them, because although water wings help the child to float, they do not prevent him/her from accidentally going under water and potentially drowning. Inflatable armbands are not a life-saving device. Mistaking them for one can create a potentially fatal false sense of security.
