Kusu Girls Front Zip Long Sleeve One Piece - Blue Mosaic
|
The Girls Long Sleeve Swimsuit That Ends the Sunscreen Negotiation Picture a harbour lined with blue tiled walls, and a small person sprinting past them towards the water. The Kusu Girls Front Zip Long Sleeve One Piece is made for exactly that energy: a girls long sleeve swimsuit with UPF 50+ coverage over the arms, chest, back and tummy, plus a front zip that gets her in and out without a wrestling match. Fewer sunscreen stand-offs, more cannonballs. It's made from REPREVE® recycled polyester, turning plastic bottles into soft, durable stretch that holds up to chlorine, sunscreen and every sandcastle project. The torso is lined for comfort, and sizes 10 to 14 come with removable padding for growing girls. Blue Mosaic is inspired by indigo textiles and coastal ceramics, blending geometric motifs with deep ocean blues to capture the artisanal spirit of historic trading ports. Want to match? Mum can twin in the Costa Brava High Neck One Piece Swimsuit in Steel Blue / Blue Mosaic, and the boys in the Southport swim trunks. Why You'll Love It • Long sleeves and a high neck for UPF 50+ coverage on arms, chest, back and tummy • Front zip for quick, fuss-free changes • Lined torso, with removable padding in sizes 10 to 14 • REPREVE® recycled polyester, resistant to chlorine and sunscreen • Matching family prints across the Port of Call collection Fit and Sizing Available in sizes 4 to 14. Check the size guide or use the Size Match tool to choose by your child's measurements. Between sizes? Size up for a little room to grow. Questions, Answered Is the Kusu easy for kids to put on? Yes. The front zip opens the suit wide, so little ones can step in and zip up with minimal help. How much sun protection does the Kusu give? The fabric is rated UPF 50+, blocking over 99% of UVA and UVB rays, and the long sleeves and high neck cover the areas that burn most easily. How should I wash it? Hand wash in cold water and gently squeeze out the water without wringing. Roll in a towel, then lay flat to dry in the shade. Is there a matching style for mum? Yes. The Costa Brava High Neck One Piece Swimsuit comes in Steel Blue / Blue Mosaic, and dad can match in the Southport Men's Swim Trunks. |

Frequently Asked Questions
How do I know what size swimsuit to order?
Check out our size guides for all sizing, measuring and fitting guides.
What makes your swimsuits sustainable?
Aside from using fabrics derived from recycled plastic waste, many of our styles are reversible and multi-use (swim and activewear) so you can get maximum use out of your swimwear. We make gender neutral options for kids so the pieces can easily be passed down. We also use the highest quality fabrics so your swimsuits last as long as possible. Find out more here.
How do I wash my swimsuit?
To maximize the life of your spandex swimsuit (i.e. stretchy women’s and kids pieces), we recommend hand washing it in cold water and gently squeezing it dry. Avoid violent wringing, please! To absorb water before laying it out to dry, roll your swimsuit in a towel and gently squeeze. Lay flat to dry in the shade. Check out our guide to make your favourite swimsuit last longer.
If you really need to put your swimsuit in a washing machine (no judgement, life's too busy to hand wash stuff, we get it), wash it in a mesh laundry net in cold water on the delicate cycle. It's best to use a gentle detergent, like a baby laundry liquid.
For men’s and boys’ swim shorts (i.e the non-stretchy ones) you can machine wash them in 40 degree water.
