Sitting atop the marine food pyramid, tiger sharks play a significant role in balancing the tropical and temperate water ecosystem, which is why we celebrate their beauty and support research that informs management of their population.

Advocate Apparel Inspired by tiger sharks (Galeocerdo cuvier)

Tiger sharks are classified by the International Union for Conservation of Nature (IUCN) as “Near Threatened”, and thus, research, education and outreach is essential to ensuring healthy populations. As one of the ocean’s largest predators, these critical species sit at the top of the food chain, helping to regulate the delicate balance of populations of those beneath in the ecosystem. Decreased populations can result in trophic cascades, impacting the abundance and behavior of other species lower on the food chain.

Multiple research methods have shown that some species of sharks have declined in population by 90% or more during the last several decades in areas where they were formerly abundant. These declines are due to direct targeting in commercial fisheries, mostly for their fins and sometimes meat. Additionally, sharks are often caught unintentionally as bycatch in many other fisheries, caught and killed in some recreational fisheries (unlike catch and release), and may also be impacted by humans more indirectly through threats like habitat loss, pollution, and human-driven declines in the fish species sharks rely on for food.

"We are so proud of our collaboration with Waterlust. Not only does their support help enable our shark conservation research, but the apparel itself is a walking billboard for marine conservation. I love it when people on the street stop to ask me about my tiger shark board shorts. It's an opportunity to start a conversation about the wonders and perils faced by sharks and how the average person can help make a difference.”

Great fit and looks!

More than satisfied, I'll be going back for more! Functional yet fun and lovely and with a good reuse of our ever present friend, plastic.

Best shorts I’ve owned

Probably the most comfortable general bad ass looking item of clothing I’ve owned in my time on this beautiful planet. The day after I got them I ordered another pair! Keep up the good work

Great Customer Service

I just wanted make sure credit is given when great customer service is received. I purchased some waterlust boardshorts and the fit was to big so I just stopped wearing them. I was on the website recently and looked at the size chart and realized although my waist is a 35 they suggest a 33 boardshort. I contacted the company and although I ordered mine quit a long time ago I received an email from the head of the company saying he would exchange them and sent the new shorts before I even returned the old ones. You rarely see customer service like that anymore. So not only do I have new shorts that fit and I love but I will be buying another pair. Thanks for the great customer experience.

Fantastic quality

We are big fans of Waterlust products. Living in Hawaii, and being hard core divers and swimmers, we put our swimwear through serious testing! The color has held up great in all my Waterlust products. I got these board shorts for my husband. The quality is much higher than other very popular brands of board shorts! Because of the durability, they are worth the price!

Amazing customer service

The shorts are awesome and the customer service is simply superb (I had a special case for exchanging into a smaller size and the support I received was outstanding).
