The Aurora Starry Whale Shark Wetsuit is a print-led bikini suit for warm water: manta rays drifting through a star-filled sky, wrapped onto a body-hugging cut. The large silhouettes across the body are mantas, and the scale of them is where the whale shark in the name comes from. It is a suit meant to be noticed on the surface and remembered underwater.
At its core this is a 2mm printed bikini wetsuit — limestone neoprene outside, a quick-dry 360° stretch lining inside — with two ways to close it. Take the backless cut if you want your shoulders free and a suit you can pull on alone; take the back-zip cut if you want the fit locked down for surfing and rougher water.
It fills the gap between swimwear and a full wetsuit. A swimsuit is fine for twenty minutes and then the shivering starts; a 3 mm suit is too much for the warm water most of us travel to. This sits in the middle, which covers tropical trips, summer coastal sessions and pool training in a cool building.
It packs the way travel gear should: thin, light, quick to dry and easy to roll into a corner of a bag. Wear it for a morning dive, rinse it at lunch, and it will be ready again the next day.
Everything about how this suit feels comes down to what it is made from: 2 mm limestone neoprene, chosen for flexibility and durability at this thickness, bonded to a 360° stretch lining that gives in every direction rather than only across the body.
That combination does more than it sounds. A bikini wetsuit has to hold a thin layer of water against your skin to keep you warm, and at the same time let your shoulders rotate when you paddle and your ribs expand when you breathe. A lining that stretches in all directions is what allows both, which is why the suit behaves more like a second skin than a shell.
The lining also dries quickly. A suit that comes off wet at lunchtime is ready to pull on again an hour later, and it will not sit heavy and cold at the bottom of a bag on the way home.
Panels are shaped and joined so the suit lies flat against you. Flat panels are the simplest way to keep drag down, and low drag is the difference between a suit you forget about mid-session and one you keep tugging at.
The printed surface has a faint sheen in sunlight. Treat it like the fabric it is and it keeps that look for seasons, not weeks.
Both versions are the same 2 mm printed bikini wetsuit and both wear the same print. What changes is the way the suit closes across your back, and that changes how it feels once you are in the water.
The backless cut is a pull-on. With fewer panels across the back, your shoulders rotate without anything pulling against them, and there is nothing to fasten before you get in. Choose it if you swim, snorkel or spend a session shooting photographs, because your arms will be above your head far more often than they will be bracing against a board.
The back-zip version closes down the spine and holds the suit more firmly around the torso. Surfers usually prefer it: a duck dive or a wipeout pushes on a suit from every direction, and a fit that stays closed means less flushing and fewer adjustments between sets.
Getting in and out follows the same logic. A back zip takes a moment and usually a hand from someone else to finish; the backless cut goes on and comes off alone, which is the friendlier option when you are changing on a beach or the deck of a boat.
Either way the leg is cut as a bikini, so you keep the hip range that a high-cut suit gives you.
A neoprene suit should feel snug when you first pull it on — closer to a firm hug than to a swimsuit. It eases slightly once you are wet, and that initial compression is what holds a thin layer of water against your skin instead of letting it flush straight through.
Measure before you choose. You need height, weight, chest at the fullest point, waist at its natural line and hips at the widest point; the size chart below uses all five, because a 2 mm suit is only as warm as its fit. Choosing from a chart at an online bikini wetsuit store is the step most people rush, so measure over underwear rather than over clothes, and compare the numbers to the chart rather than to the size you wear in a dress.
The range runs from XS to 3XL and also includes short and tall builds, marked with an S or a T in the size code, so the same chest and hip measurements can be matched to a shorter or longer body. If your height supports one code and your measurements to another, send us both and we will tell you which to take.
Between two sizes the usual rule applies: choose the smaller for compression and a suit that stays put in the surf, the larger for easier entry, particularly in the back-zip cut. People who buy women wetsuit pieces a size down for a closer look usually end up with seams that pull and a suit that fights them all session.
The bikini cut sits close at the waist and high on the hip, while the stretch lining keeps the leg openings from digging in. Long sessions, salt and sun are what this fit has to survive, and the flat panel construction is what makes that possible. Stretch panels and fast-drying materials keep the suit flexible and resilient, while the backless and zippered variations make it easier to put on and take off without losing the snug fit you need in the water.

Underneath the suit. For most people, nothing at all. The Aurora is cut as swimwear and the lining sits softly against bare skin, so adding a bikini underneath only introduces seams that press, edges that roll and fabric that bunches the moment you start moving. Pull it on over bare skin and it sits the way it was shaped to sit.
If you prefer a layer. Some people still want one, and that is fine. Choose a smooth, seam-free swim bottom in a thin, quick-drying fabric — no knots at the hip, no ties, no textured seams that will leave a line across your skin after an hour in the water. Cotton is the one to leave in the bag, because it holds water and stays cold against you long after you have left the sea.
Under a thicker wetsuit. This printed bikini wetsuit is not built as a base layer, and it does not behave like one. The bikini cut leaves your arms and back open, so there is no continuous surface to slide against the inside of a full suit; the open edges and the seams catch instead, and neoprene against neoprene grips rather than glides. Pulling a full suit over it usually ends with the print rucked up around your waist and the outer suit flushing at the shoulders.
Warmth that does not add up. A 2 mm suit worn under a thicker one does not simply add 2 mm. Warmth in cool water comes mostly from the outer suit sealing at the wrists, ankles and neck; an inner layer that bunches breaks that seal and lets water move through. You finish the dive colder than you would have been in the thicker suit alone — and the manta-and-stars print, which is the whole reason to choose this suit, stays hidden.
What to do on cold days instead. If the water or the length of the day calls for more, move to a full-coverage suit a millimetre or two thicker and keep the Aurora for the warm-water sessions of the same trip. On the boat, layer over the suit rather than under it: a windproof shell or a dry robe between dives does far more for you than anything worn beneath the neoprene.
Between sessions. Whatever you wear or don't, rinse the lining after every use. Seawater, chlorine and sunscreen stay in the fabric, and they are what make a suit stiffen and smell over a season.
Designed for women who move between different kinds of time in the water, this 2 mm printed bikini wetsuit keeps warmth without holding you back. The manta ray and starry sky print gives it a look of its own, so it feels as at home on the beach as it does in the sea. Whether you are surfing, swimming or diving in warm to moderate water, it keeps drag low and comfort high through a long session. For anyone after a spring wetsuit that performs and still looks distinct, this is one to consider.
The suit is made from durable 2 mm limestone neoprene, with a 360-degree stretch lining that keeps it elastic as well as warm. Fast-drying fabric means less waiting between sessions, and the bikini cut leaves you free to move. Backless and zippered versions let you choose the fit that suits you, and careful construction keeps water resistance low so swimming feels easier. If you want to confirm which thickness or closure most closely matches the water you dive in, just ask and we will talk it through with you.

Snug enough that it feels like a firm hug, with no loose folds across the small of your back and no gaping at the shoulders. Neoprene eases a little once it is wet, so the fit you feel dry is the tightest it will ever be. People who buy women wetsuit sizing a size up just in case usually end up with a suit that gaps, flushes on every dive and finishes colder than the smaller size would have been.
Nothing, for most people. The suit is cut as swimwear, and a bikini underneath only adds seams that press and bunch once you start moving. If you prefer a layer, take a smooth, seam-free bottom in a thin fabric. Fit is the question worth settling first, so if you are between sizes, ask before you order from an online bikini wetsuit store.
The print sits on the surface of the fabric, so it ages with the suit rather than separately from it. Rinsing after every session and drying in the shade keeps the colour sharp far longer than leaving it damp in a bag or drying it on a hot rail. Rough surfaces — concrete, non-slip decking, velcro — scuff it faster than salt water ever will.
Yes. The 2 mm neoprene and quick-dry lining work as well in a chlorinated pool as in the sea, and the suit comes into its own as a cute freediving swimsuit for long training sets where a swimsuit leaves you cold between intervals. Rinse it in fresh water after every pool session — chlorine is harder on neoprene than salt is.
It is not designed for that. The bikini cut leaves the arms and back open, so it does not slide smoothly under a full suit and can bunch at the seams. Treat it as the suit for warm-water sessions, and move to a full wetsuit when the water or the length of the day calls for one.
