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!
The interface where air and water meet is a magical place, the physical crossroad where terrestrial and aquatic life on Earth interact. But not only is it our gateway to the submerged, the water's surface is also where heat is transferred to and from the atmosphere. Imagine this energy flowing through you the next time you float suspended between these two worlds.
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.

We stand behind every product we make. If you have a problem, we will solve it with the relentless determination of a salmon swimming upstream to spawn.
Approximately 40% of humans on Earth live within 100km of the ocean and currently 190 million people globally live at elevations below the projected high tide line for 2100 under low carbon emission conditions. In other words, the water is coming and we need to prepare!
Coastal resiliency is a term used to describe the ability of a community to “bounce back" after hazardous events such as hurricanes, coastal storms, and flooding – rather than simply reacting to impacts, and it is becoming one of the most important fields of study in science & engineering.
At the Alfred C. Glassell Jr. SUSTAIN Laboratory at the Rosenstiel School of Marine & Atmospheric Science, scientists utilize a state of the art wind/wave tank to better understand these intricacies. 10% of your purchase will be donated to support the graduate students that work in this lab. Specifically, the funds will be used for creative projects that enable the students to communicate their work to the broader public such as through film, photography and art.
"The SUSTAIN laboratory's collaboration with Waterlust has been a great way to engage students in outreach. So many of them at all levels are interested in bringing our research on hurricanes and climate resilience to the general public. I also often show some of the Waterlust videos in my classes to highlight to the students how engaging this work can be when presented in an interesting way."

Great fit and great design as always
I just tested out my new sun-shirt on a super hot and sunny day! I love it! The color is fabulous and the fabric is soft with the perfect amount of stretch! It was very cool and the hoody part fits well too! I’m about 165lb, 36D and the medium fit great! I’d love to get another one in a different color! Thanks for making quality products in amazing prints!
Love this shirt so much, both for usefulness in sun protection and because it's just so darn pretty! I fit the dimensions of the medium size but like my sleeves longer and a looser overall fit, so I sized up to a large and it's perfect. The return/exchange process was very easy and though I've only worn this sun shirt once so far, I hope and expect to get many fun wears out of this!
This is lovely- I haven't worn it yet. The medium size is just right- it corresponds to other tee's and gym clothes that I also wear in size "M".
SO comfy and exactly what I needed! I love how long it is, so even if it rides up a little while swimming, I'm still fully protected from the sun. I also like the thumb holes that keep the sleeves in place. And the fabric is SO breezy. I wore this out in 95+ degree weather and as soon as it was wet, it kept me cool for a long time.
4 stars instead of 5 because the sizing seems a little inconsistent. I also ordered legging and a swim top, all in the 3x size, and while the others are a little tight, this is actually a little loose. Because of this, it causes a bit of drag when swimming, but not enough to be a problem. However, if you are expecting/wanting a really form fitting rash guard, you may want to size down.
Also a SUPER minor complaint but I don't really want/need the hood. It creates a little extra drag, but it's easy enough to tuck into the neckline to keep it out of the way
A little too long. Don’t care for the opening at the end of the sleeves
