The essential UV swim jacket, certified UPF 50+, that will effectively protect your whole upper body from UV rays when you're swimming or doing other water activities.

It's easy to put on thanks to its full zip, and can be removed when you don't need it. Thanks to its removable foam shells, you can choose to wear it as your only swimsuit top, or over your bikini top. The fabric also dries very quickly, so you can stay warm and protected from the wind once you're 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 go one size up from your usual size (see size guide).

    UV swim jacket

    I bought this jacket for a holiday that involved paddle boarding and snorkelling, it kept me from burning and as a result I could do these activities for longer. The jacket is a snug fit so did not drag in the water. It is light weight and remained so when went.
