Advocate Apparel Inspired by the largest fish in the sea, the whale shark (Rhincodon typus)

Whale sharks (Rhincodon typus) are fish, not whales - allowing them to hold the esteemed title of "largest fish in the sea" (since sharks are fish too!). These charismatic creatures can reach lengths of 12 meters (40 feet) or more! Despite their large size, they feed on some of the smallest organisms in the sea, plankton. Hanging vertically in the water column they're able to suction feed and filter these tiny organisms through their gill rakers much like a giant vacuum cleaner pulls dust and dirt from a kitchen floor, filtering the fragments into its chamber within.

Unfortunately, approximately 100 million sharks are killed every year by humans, through direct targeted fishing efforts as well as unintended bycatch from other fisheries. The whale shark is one species of shark that is particularly vulnerable to this commercial fishing due to their high value in international trade, in addition to their highly migratory nature and normally low abundance. Research into the lives of these gentle giants can help us to manage their populations and keep these magnificent fish in the ocean where they belong.

5% of sales from your purchase of this product are donated to the Marine Megafauna Foundation

The Marine Megafauna Foundation is helping to shed light on the population structure, migratory patterns, and the conservation requirements of these threatened sharks. Created in 2009, they aim to research, protect and conserve the large populations of marine megafauna (large marine species) found along the Mozambican coastline. Almost all whale sharks encountered by divers are juveniles and most are males. Where the school-bus-sized mature sharks swim, what they eat, and where the females give birth has long been a mystery, however their team is now very close to making these discoveries. 5% of sales from your purchase will go to the Marine Megafauna Foundation for satellite tags that are needed to track the movements of these large female whale sharks.

“Waterlust's support provides critical seed funding for us to rapidly develop and implement whale shark conservation projects in areas where this globally-endangered species is most at risk. This includes Mozambique, where our research and awareness work helped the government decide to fully protect whale sharks just a few weeks ago. We love working with a company that is so committed to making a positive change in the world.”

WOMEN'S Whale Shark Warrior Sun Shirt

I have not yet gone swimming in my new Whale Shark Warrior Sun Shirt and matching bicycle shorts, but I have tried them on and they are darling! Fit is perfect and flattering. Fabric is very nice and print is very cool. Can't wait to try them out.

In love!

I absolutely love this shirt! It fits well, is so comfortable, and the beautiful pattern makes my baby marine scientist heart happy. I cannot wait to get it in the water during my next dive! Rest assured, this will certainly not be my only piece from waterlust. I’m already eyeing my next purchase!

Ready for Liveaboard!

Bought the Whaleshark Sun Shirt for upcoming dive trip on a liveaboard. The material is super soft, stretchy, and very high quality. Love the thumbholes and hoody w/ ponytail hole. For reference I am 5 Ft short, 128lbs, athletic built and the S (Strong), fits perfect, not too tight, and not baggy. I plan to wear it while diving, with the matching Whale Shark leggings. The sun shirt will also be versatile and comfy enough to wear on the plane, on hikes, out to dinner, and just about anywhere else! Looking forward to wearing other Waterlust Designs! So happy to have found you guys!
