  • “I've ordered several of these sunsafe suits over the last couple of years and they are the best. They usually last me two summers and they have still retained shape and colour. Great product even for the strongest sun.”

How to choose a kids' sunsuit

Every sunsuit covers the body in one piece. Choose by how much of the arms and legs you want covered.

  1. Short sleeve sunsuit Short sleeve sunsuitShoulders, body and thighs
  2. Long sleeve sunsuit Long sleeve sunsuitNeck, arms, body and thighs
  3. Full-body sunsuit Full-body sunsuitNeck to wrists and ankles

Coverage A full-body sunsuit covers the most, from a high collar to the wrists and ankles. A short sleeve sunsuit covers less but will naturally provide slightly greater flexibility.

Sizes Sizes run by age from 4 to 14 years in two-year steps.

Common questions about kids' UV sunsuits

What is a sun safe swimsuit?

A sun safe swimsuit, also called a sunsuit, UV suit or stinger suit, is an all-in-one swimsuit made from fabric that has been tested and rated UPF 50+, so it blocks at least 98% of UV rays from the skin it covers. It covers the torso and thighs in one piece, with short sleeves, long sleeves or a full-body cut to the wrists and ankles, and a high collar for the neck. It is swimwear, not a wetsuit: the fabric is thin, stretchy and dries in minutes.

Can the sun get through a normal swimsuit?

Yes. An ordinary swimsuit is not tested for UV, and a thin or wet one can let a large share of the UV through. A sunsuit made from certified UPF 50+ fabric blocks at least 98% of UV rays, wet or dry, and covers far more skin than ordinary costumes or trunks.

Is a UV suit better than a swim top and shorts?

For sun protection, yes. A one-piece has no gap at the waist when a child bends or reaches, and nothing rides up, so the lower back and tummy stay covered. A swim top with shorts or leggings covers the same skin when it stays in place, is quicker for toilet trips, and lets you mix sizes if a child is long in the body. Many families keep one of each.

Does a UV suit keep a child warm in the water?

A little. The fabric is thin swim fabric rather than neoprene, so it is not a wetsuit, but covering the arms and body takes the edge off the wind when they come out of the water and stops the shivers on a breezy beach. For cold British sea swimming, wear a wetsuit over the sunsuit.

Why choose equatorsun for kids' sunsuits?

Ordinary children's swimsuits are rarely tested for UV and they can let through up to 10 times more UV than UPF 50+ children's swimsuits. Every equatorsun piece is tested to the AS/NZS 4399 or EN 13758 standard and certified UPF 50+, which means the fabric blocks at least 98% of UVA and UVB rays from reaching the skin it covers, and the protection cannot wash out or wear off.
