Black Circularity FULL-BODY Sun Suit

Educational resources included with every purchase. Learn more.

Designed for diving, snorkeling, swimming, surfing, kiting, winging... you get the idea. If the ocean is your happy place but you recognize the importance of skin protection, these suits are for you! Versatile too - wear it alone or as a base layer to help you easily slip in and out of your wetsuit on those colder days.

Made from post-consumer bottles AND old textiles through our Take-Back Program. We collect your old clothes, put them in a wood chipper (joking…kinda), and convert them into fiber, then fabric, then back into brand new clothing. Because textile waste comes in different colors, the resulting recycled fiber ends up looking brown, like a child finger-painting with ALL the colors at once kind of brown. Yuk! To fix this mess, the fibers are dyed black during the recycling process.

    1. UPF 50+ sun protection (max rating achievable)
    2. 100% chlorine, sun, salt water, and sunscreen resistant
    3. High neck collar and thumbholes at wrists to protect the tops of your hands
    4. Raw hem and internally stitched bar-tacks allow for customizable leg inseam lengths of 31”, 29”, 27”, 25”, 23”, 8”, 4”, and 2”. Crop the long legs to your favorite shorty length, or customize for your height. Learn how here.
    5. Strong front zipper for easy entry and adjustable neck/chest coverage
    6. Raglan cut sleeves for great range of shoulder movement
    7. Fibers mechanically engineered for quick-dry, moisture-wicking and breathability
    8. Resilient 4-way stretch and recovery for shape retention in and out of the water
    9. No shelf bra or padding. For more support, we suggest wearing a bikini top underneath
    10. Tag-less for comfort
  • Our signature fabric is sleek, soft, and luxurious, while strong, substantial, and resilient. It’s got a gummy, supportive, and smoothing stretchiness you’ll love, comfortably hugging you in all the right places.

Apparel that supports textile recycling

According to the EPA, 87% of apparel textiles are not recycled annually in the United States, meaning millions of tons of old clothes are piled into landfills every year. While recycling infrastructure exists for things like plastic bottles and aluminum cans, textile recycling is far less developed and accessible. This is a missed opportunity because the raw materials within some kinds of clothing (like ours!) can be used to create entirely new fabric, as long as it’s done carefully. By purchasing products made from recycled textiles, you are financially supporting the infrastructure that enables recycling to happen and signaling to manufacturers that you value circularity.

In the world of environmentally responsible fabrics, we think there are two clear leaders from an end-of-life perspective: those that are entirely made from natural fibers, and those made entirely of synthetic fibers. 100% natural fabrics like organic cotton are beneficial because they are biodegradable and recyclable, while 100% synthetic fabrics are beneficial because they are recyclable. Fabrics that blend natural and synthetic fibers together are not currently biodegradable or recyclable with today’s technology, which is why we don’t make them.

Easiest customization ever!

Thicker than a standard swimsuit without the cloying heaviness that some "made of recycled plastic bottles" fabric is prone to; I love the texture of this sunsuit! The hidden bar tacks make hemming the legs a cinch—all you need is a ruler and a decent pair of scissors and you're good to go!

Seems perfect

I haven’t used it yet, but the material is perfect and I was able to fit my curvy size 16 body into it comfortably with room to spare. I got a 2x but I do think an XL would have fit. Excited to use it for paddle boarding!

Fabulous quality, fit , and comfort

I’m loving my new suit and very pleasantly pleased with the garment quality; fit and comfort. It’s an investment piece which helps sustainability, is comfortable to get on, wear diving or snorkelling in warm waters or under wetsuit when it’s colder. As a bigger woman I was concerned about how this would fit and look but it’s really nice to wear. Now looking forward to going to see the giant cuttlefish mate in winter in July here in our cold southern ocean as well in the tropical waters of Great Barrier Reef when I head north soon.

Wonderful for Deep Water Pool Class

Love this sun suit. I’ve only worn it once, so I don’t know about long-term wear. The sun suit is more substantial than I thought, and I could feel the weight of it in the pool compared to swimsuit leggings + tank. I bought it to wear in fall & winter in the pool for deep water exercise. I was much warmer and better protected from the sun, wind, and rain. The suit is a great design. I followed the size reco and it was accurate. I’d love petite sizing as even though the legs can be cut, the arms (can’t use thumb holes) and body are too long.

Best piece of diving attire I’ve bought in a long time.

This is possibly the comfiest bit of dive clothing I have bought. Out of the water, I found it kept me at an ideal temperature, even in the sun. In the water, I found it light, unrestrictive and warm (water’s about 24/25 c where I am)… I was a little skeptical about having the zip at the front but that was a stroke of genius on the part of Waterlust - sooo much easier to get in and out of and doesn’t cause any discomfort. The real winner for me though is the fact I only have to put a bit of sunscreen on my face now. My only criticism is that this should be marketed as a unisex item… I am male and I can say honestly, it fits very well and looks perfectly respectable. Well done Waterlust 🙌

Love it

Fits great and feels great.
