Curated for the Current: Waterlust

I first discovered Waterlust while searching for a sun suit before a dive trip to Florida in 2022. What started with a Whale Shark Sun Suit quickly turned into a full-blown obsession. Today, you'll rarely see me wearing anything else under my wetsuit. During a recent conversation with founder Patrick Rynne, I learned that Waterlust was never intended to be an apparel company at all. Instead, it began as a creative experiment in science communication and has grown into a brand that connects people to ocean conservation through art, education, and community. This is the story behind one of my favorite companies and why Waterlust is so much more than a rash guard.

Curated for the Current: Stream2Sea

I first discovered Stream2Sea on a dive boat in the Florida Keys shortly after becoming a scuba instructor in 2022.

Fantastic Fiji 2026: Diving Into Paradise on Taveuni

Some destinations give you incredible dives. Fiji gives you an entire experience.

Where vibrant soft corals explode across towering walls, dolphins race alongside boats, rare macro creatures hide among the reef, and every current carries the promise of something unforgettable.
