Snap has teamed up with a cruise line to deliver waterproof Spectacles that you can swim with. In partnership with Royal Caribbean, it is encouraging fans to capture and share stunning stories from up to 150 feet below the surface of the sea.

Spectacles may not be quite as hot as they were when they made their debut last September, but they’re still going strong — and expanding to new markets around the world. Now they’re not just for use on land. Snap and Royal Caribbean have created “SeaSeekers,” which you can wear for up to 30 minutes under water.

They’re just a prototype for now, Business Insider reports, but Snap is planning to roll them out to customers this fall. They’re currently being tested by two professional divers, marine biologist Gabriela Nava and wildlife photographer Roberto Ochoa, who have been using them in the deep sea to capture the underwater world in all its glory.

SeaSeekers are built into diving goggles, so you don’t need to carry any additional equipment. They negate the need to strap on a GoPro or specialized camera equipment, and because they’re worn on your face, you have more control over the footage you capture.
