Whether hitting the water for a sunny day adventure or tackling that long postponed yard project at high noon, our silky smooth sun masks (neck gaiter) protect your nose, ears, lips, cheeks, and neck from UV exposure.
Intimidating stripes cover one of the ocean’s largest apex predators. 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. 5% of sales will be donated to the Shark Research and Conservation Program (SRC) at the University of Miami, helping to fund important research focused on the ecology, movement and conservation of tiger sharks as well as other local shark species.
Our silk-weight fabric is feather-light, silky smooth, and cool to the touch, engineered for all-day sun protection without the heat. So breathable you'll forget you're wearing it, so protective you'll never want to take it off.
91% Repreve® RPET (recycled polyester made from post-consumer plastic bottles), 9% spandex
Safe, premium performance yarns: Our high-quality, fully traceable yarns are sourced through sustainable partners in the U.S. These materials meet rigorous chemical safety standards and are independently verified for over 1,000 harmful substances like BPA and PFAS through OEKO-TEX® STANDARD 100 certification.
High-quality, responsible printing: Our products are printed using heat transfer sublimation, a printing technique that is widely considered to be the safest for both workers and the environment. It requires no water, eliminates dye from entering water systems, and minimizes ink and fabric waste. All the inks and dyes we use are also OEKO-TEX® STANDARD 100 certified.
Recycled materials, minimal waste: Our commitment to environmental responsibility starts with sustainable fibers and yarns. We use synthetic yarns made from recycled plastic bottles, which helps remove and repurpose existing plastic.

Flat $5 shipping on every U.S. order. Shipping is a real cost, we keep it low, flat, and honest. No inflated prices hiding “free” shipping, no pressure to over-buy to hit a threshold. Just a simple $5 that encourages more intentional ordering, which means less waste and fewer emissions. International orders just pay cost to ship, which is calculated at checkout.
Orders are lovingly packaged using minimal packaging and eco-responsible materials, and shipped from our wonderful partner warehouse in Pennsylvania within the same or next business day. We’ll email you with your tracking info as soon as your order is shipped.

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.”

the Shark Research and Conservation Program at the University of Miami
The Shark Research & Conservation Program (SRC) at the University of Miami conducts cutting-edge shark research while also inspiring scientific literacy and environmental ethic in youth through unique hands-on field research experiences. Every year, SRC brings out thousands of people, mostly school-children, on their research boats to survey, sample, tag and study sharks. Opportunities are especially made available for under-served populations in the sciences. SRC’s science focuses broadly on understanding the effects of environmental change on the behavioral ecology and conservation biology of sharks in a human‐altered world.
I purchased the Tiger Shark Sun Mask back in 2019, and I must’ve been so busy outside enjoying it that I never got to writing a review! The version I purchased didn’t have the tie-back feature yet, which I’m sure makes it all the better. But even then, it was an accessory I always had with me when I was out on boats in the tropical sun or spending time at the beach.
It provided decent protection for my neck, which I’m sure is even better now that it can tie back to provide more coverage. But one of my favorite things about it is how easily it could fold into a headband. I often wore one as a headband and one around my neck at the same time. The prints are pretty great, and I’m a fan of Waterlust’s commitment to supporting ocean conservation and research.
The only thing I’d change would be to make it double-sided so that the print is even more visible.
Perfect for the field!
I love this buff! I love that I can adjust it to be snug around my face, and tuck the flap in the back into my shirt for extra protection!
