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.”

Quality Rashy

This is my 2nd order with Waterlust - excellent product. Holds up well after many uses. We scuba dive and snorkel with these tops & the leggin’s’ that I ordered before. Highly recommend. Prompt delivery as well.

Light and comfy!

The women's one was out of the stock so I bought men's instead. I would recommend to downsize 1 size if you do so. :P

Perfect for a day in the sun or rain!

I wore this for 4 hours in the sun and rain...it kept me cool in the sun and warm in the rain! The coverage is unrivaled! Not a burn in sight...and my bald head and shoulders are the first to burn no matter how much sunscreen I put on. Fabric is so smooth, soft, and light that it's like nothing is on!5'11" 218lbs and the Extra Legendary gave me a loose fit.

Whale shark pattern long sleeved rash guard

Beautiful pattern on nice rashguard material. Appreciate the well reinforced thumb holes and hoodie. All-over sewing looks to be durable. Only suggestion would be a sewn in loop for hang drying.

Ma La (Atlanta, GA, US)
super comfortably sun shirt

I couldn't be happier with this sun shirt. Extremely comfortable, fantastic print. Hood is large enough to be comfortable but not floppy.
