The essential anti-UV swim jacket, UPF 50+ certified, that will effectively protect your entire upper body from UV rays during swimming and other aquatic activities.

It is easy to put on thanks to its full-length zip, and can be removed when no longer needed. Thanks to its removable foam shells, you can choose to wear it as your only swimsuit top, or over your swimsuit top. Its fabric also dries very quickly, so you can stay warm and protected from the wind after getting out of the water.

Want to wear it like a classic jacket, over a tank top or beach dress? It's possible! We simply recommend that you size up one size above your usual size (see size guide).
This pretty white sailor with its blue stripes is sure to brighten up even the sunniest days.
