Gorgeous Zoggs Sea Unicorn Swimsure Jacket! Designed for toddlers aged 2-3 years (approx. 15-18kg), this jacket is the perfect step-up from armbands. Unlike bulky life jackets, the Swimsure vest features fixed, puncture-proof floats that encourage a natural swimming position, giving your child the freedom to use their arms and legs to find their balance in the water.
