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.

“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.”

Perfect shorts for marine science

I love these shorts. The length. The fit. The craftsmanship. Only two small concerts. The drawstring could grip better. Any pressure from inside loosens the bow you tie. And the lining. Why white? Navy please. If it's sitting that close to your body for an entire day. White would get sweaty and discolored

Hi Richard! Thanks so much for the feedback! The reason we chose white actually comes down to practicality and availability. We custom-make all of our own fabrics, so when we make a color, we need to stock it for other products on the shelves to maximize usage/minimize waste. We use our super soft sun shirt fabric for the liner and thought a dark color would be too hot for long sleeves in the sun. Currently, we only stock two colors in that fabric- white (which we use for printing all of our prints on), and a limited edition batch of Sea Glass Blue (a light blue gray shade). We're running low on the Sea Glass Blue, which is why we're using the white for the liner right now. But not to worry, all of our prints are 100% bleach, sun, chlorine, salt, etc. safe (guaranteed not to fade ever!), so any staining is 100% treatable. Since the sun shirts have been so popular, we have plans to add more solid colors in the future and once we have those, we may switch the lining to a different color based on availability. Hope that gives some insight into our decisions and so glad you like the shorts otherwise! :)
