Boys’ swim costumes – long-sleeve UV suits for confident summer play
Built for long days outdoors, designed for comfort
For boys who never stop moving, a simple top and bottom aren’t always enough. That’s why Juillet Juillet has created a range of boys’ UV swim costumes—long-sleeve, short-leg one-piece suits that combine maximum sun coverage with absolute freedom of movement.
Perfect for children with sensitive skin, or those who spend hours in and out of the water, these suits offer a practical, all-in-one solution that simplifies sun protection—without ever compromising on comfort or style.
High-coverage protection that stays in place
Made from UPF 50+ certified fabrics, our swim costumes provide a physical barrier against more than 98% of UVA and UVB rays. They’re designed to cover the chest, back, shoulders and arms, with short legs that allow easy movement while still offering coverage on the upper thighs.
Because the protective power is woven directly into the fabric, there’s no chemical treatment, no fading, and no compromise on safety—even after repeated swims or washes. It’s durable, reliable, and gentle on the most delicate skin.
Parents love it because it reduces the need for constant sunscreen reapplication. Kids love it because it’s light, soft, and easy to wear—from beach to boardwalk.
Designed for play, made for the sea
These swim costumes are built for real-life summer. The quick-drying, breathable fabric keeps boys cool and comfortable, while the stretch fit allows full range of motion—whether they’re swimming, running, or digging in the sand.
The front zip-up closure makes dressing easier, and the design holds its shape without sagging or sticking. Resistant to chlorine and salt, it’s a suit that’s ready for everything summer throws at it.
Minimalist lines, sun-smart attitude
Our boys’ UV suits are more than practical—they’re also effortlessly stylish. With sporty cuts, bold colours, and that signature Juillet Juillet retro-modern spirit, they look as good as they perform.
Pair them with a UV sun hat for full upper-body protection, or add a towel and sandals and they’re ready for lunch by the sea.
In a nutshell
Juillet Juillet's Boys’ Swim Costumes offer long-sleeve, UPF 50+ protection with the ease of a one-piece suit and the freedom of short legs. It’s a clever, sun-safe essential—designed for movement, built to last, and made for childhood under the sun.
