About this product
Inflatable arm bands are the simplest way to give a child enough buoyancy to stay upright while they get used to water. Each band is a PVC sleeve containing two separate air chambers. They slide up the upper arm, sit just below the shoulder, and hold the child high enough that the mouth stays clear of the surface without them having to fight for it.
The two-chamber construction is the point. A single-chamber float that develops a leak becomes useless in seconds. With two chambers, a puncture in one leaves the child with roughly half the buoyancy and time for an adult to reach them. Inflate both chambers on both bands every time – it is tempting to fill only the outer one because it goes faster, and it defeats the design.
Fit matters more than most people expect. The band should be tight enough that it does not slide down past the elbow when the arm is lifted, and loose enough not to mark the skin. Inflate to firm but not drum-hard: an over-inflated band splits at the seam, and PVC that has been sitting in a hot car expands further when it hits cool pool water.
Arm bands are a confidence aid, not a safety device. They keep a child upright in a supervised pool. They are not built for the sea, where a current or a wave will take a child faster than a float can hold them, and they can slip off a wet arm. For Coco Beach, Kigamboni or any open water, put a child in a proper buoyancy vest instead.
