Our sun shirts allow you to spend hours outside in the sun without overheating or cooking your largest organ in UV radiation. Lightweight, airy, stylish, and fun, sun protection as rad as you!
Characteristic spots and stripes adorn the largest fish in the sea forming an intricate pattern, like a warrior painted for battle. Scientists use these distinctive markings to identify individual whale sharks. Like a fingerprint, each is as unique and special as the last.
Made from recycled materials and knitted into an ultra fine, lightweight fabric, think of it as the working persons stretchy silk. So silky smooth and cool to the touch, your skin literally gets goosebumps when you put it on, but stays shielded from the sun all day on the water. You can stand in an asphalt parking lot on a hot, humid, sunny day in Miami in July at noon and still feel cool. Yep, our test team tested it…reluctantly.

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.
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.”

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!
WOMEN'S Whale Shark Warrior Sun Shirt
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!
Everything from Waterlust is beautifully made, wonderful to wear and incredibly functional.
honestly I love it so much. fits great, nice material, doesn't bunch weird, dries fast
You guys are SO SAVVY about figuring out sizes… it fits perfectly and am excited to wear it during my time in Baja California (and beyond)… I will ALWAYS return to Waterlust for my swimming needs!
