HIACOS Las-01 children's swimwear Purple size 8

Swim cap for children aged 3 to 15

The HIACOS Las-01 is a purple silicone swim cap designed for unisex use by children from toddler age through the early teens. Its waterproof construction forms a barrier that reduces hair exposure to chlorine and pool chemicals while extended coverage helps keep water out of the ears. The material is tear-resistant and shaped to follow head contours for a comfortable fit.

Suits long or thick hair; not for minimal bulk

Swimmers with long, curly or tied-back hair benefit from the expanded rear section that provides extra room and prevents tangles. The high-elasticity silicone grips securely without feeling tight, so the cap stays in place during active play. Children who prefer a barely-there feel or need an ultra-thin cap for competitive racing may find this design too substantial.

20 percent more internal space than standard caps

The defining specification is the 20 % larger volume compared with regular children's caps, which determines whether a child's hair will fit comfortably without compression. This extra capacity accommodates ponytails and thick hair while maintaining a watertight seal. If the swimmer has very short or fine hair, the additional space may not be necessary.
