This summer, want to avoid irritating, uncomfortable tampons for your swim sessions or seaside holidays? We get it… and we’ve got a super healthy, easy solution for you: the one-piece period swimsuit!

At Louloucup, we kit you out so you can experience your period as simply, comfortably and calmly as possible. With our cups, our panties and our swimsuits, you’re fully equipped to handle those special days of your cycle. Our goal? To offer you the best washable period products, the best period underwear, and the best period swimwear! 💪🏽

Yes, we know that swimming on your period isn’t ideal. It’s uncomfortable, a bit stressful, and you don’t fully enjoy the moment. You worry about accidental stains on your swimsuit, towel or lounger. You’re afraid the tampon string will show or that it will swell up. That’s why, for swimming, we swear by washable, reusable period swimwear. We’ve already told you all about our period bikini bottoms and our period swimsuits here!

Today, we’re focusing on a very specific (and gorgeous) model: the one-piece period swimsuit!

With its invisible multilayer technology that absorbs your menstrual flow without ever letting water in, the one-piece menstrual swimsuit revolutionizes your holidays. Absorption, comfort, discretion—the Louloucup one-piece menstrual swimsuit, the Louloucup model Noa, is not to be missed! Let us introduce it to you!

The one-piece period swimsuit changes your summer: in 3 key ways

After years of struggling with tampons or worrying about stains, a real solution is finally landing in your beach bag: the one-piece period swimsuit.

1 – Protection that doesn’t puff up in water

Unlike disposable products that soak up pool water, the one-piece period swimsuit stays very thin. Its technology targets only your menstrual flow. That way, you avoid the soggy diaper effect (yuck). It’s a game changer for your comfort in the water.


Hydrophobic materials repel external water. The one-piece period swimsuit never gets heavy after swimming. You keep a natural, light silhouette when you step out of the pool or ocean.


No more stressing about puffing up. Louloucup technology takes care of everything for you this summer. Just enjoy the moment.

Louloucup presents its Noa one-piece period swimsuit! 😍

  • Noa is a very pretty solid black one-piece period swimsuit.

  • Noa absorbs the equivalent of 2 tampons, making it perfect for light to medium flows.

  • The cut is flattering and high-leg, with a plunging neckline and built-in bra. The straps are thin and adjustable.

  • Available from XS to XL.

  • Rating 4.73 (30 reviews).

  • The base price before discount is €28.90.

2 – Zero leaks in the water or on your lounger!

Leak-proof protection is ensured by elastic seals. Menstrual flow stays confined to the central absorbent zone. No leaks escape. You can swim with complete peace of mind. It’s simple: the period swimsuit is made up of three complementary, ultra-efficient technical fabric layers:

  • A layer of fabric in contact with your intimate area that wicks moisture away.
  • A dense inner fabric layer with high absorbency.
  • An outer waterproof fabric layer that prevents the menstrual flow stored in the membrane from diluting into the water.

The period swimsuit creates a waterproof physical barrier that prevents blood from mixing with the bathing water, ensuring impeccable hygiene for everyone.

Once out of the water, the protection continues its work. The flow is trapped far from your skin. You stay dry on your towel, with no risk of embarrassing stains. The waterproof membrane blocks any passage to the outside. This is the maximum security promised by Louloucup’s Noa model. Reliability and peace of mind are finally here.

You can finally enjoy your holidays. Freedom is total, on the sand as well as in the water. Your period no longer dictates your plans.

3 – The one-piece period swimsuit is ultra discreet

Finally, the one-piece menstrual swimsuit is ultra discreet. It looks just like a traditional, classic one-piece swimsuit in every way. It’s impossible to guess that this swimsuit is menstrual protection! Impossible! You can’t see the absorbent membrane or anything else. You can be sure no one will know you’re on your period with this kind of swimsuit.

The Noa one-piece menstrual swimsuit guarantees absolute discretion. No one can tell you’re wearing technical protection. It’s the assurance of enjoying the sun without any visual discomfort.

The one-piece period swimsuit: a stunning form of protection

Beyond protection and absorbency, the one-piece menstrual swimsuit proves to be a unique wardrobe piece—part swimsuit, part top, part bodysuit. We adopt it without hesitation to enjoy a summer that is both comfortable and elegant.

The one-piece period swimsuit is versatile

At Louloucup, we especially love the one-piece period swimsuit for its versatility:

  • you wear it for swimming at the pool or the beach,

  • you wear it for swim class so you can swim with peace of mind,

  • you wear it for sunbathing,

  • you can wear it with a beach dress, shorts or a sarong as a bodysuit.

In short, we’re obsessed with the one-piece period swimsuit!

Choosing a one-piece period swimsuit for sports support

The one-piece style offers better support for intense activities. Unlike two-pieces, it won’t slip when you dive, for example. The tummy-hugging fit gives a welcome sense of security to anyone who doesn’t feel totally comfortable with their belly. It’s the perfect ally for your workouts.

This versatile model goes everywhere with you:

  • Lane swimming for sport.
  • Surf or paddle sessions.
  • Energetic aqua aerobics classes.
  • Diving and beach games.
  • All kinds of water activities in rivers, lakes, etc.

It’s a rock-solid guarantee of technical reliability. You can swim with total peace of mind. Your chest is well supported without being squashed. You can focus on your performance and your movements in the water. Sport never stops. Your period is no longer an obstacle to your achievements. It’s also about style and freedom of movement so you can move without any restriction.

DID YOU KNOW? 

For anyone with heavy or very heavy periods, we strongly recommend pairing a one-piece menstrual swimsuit with a menstrual cup. This small reusable internal protection fits at the entrance of the vagina and stays securely in place. Ultra reliable, it’s the ally of swimmers and athletes.
If you have a heavy flow: you can order your Noa one-piece swimsuit + the Turquoise Louloucup cup + 3 heavy flow menstrual panties to get great discounts when you order as a bundle! Keep it in mind!

Boosting teens’ confidence with discreet designs

For a teen, school swimming lessons are often a major source of anxiety. A period swimsuit takes away that huge mental load. It looks just like any regular swimsuit. No one in the changing room will notice the technological difference.


There are guides to help you find the ideal teen period swimsuit. They help parents choose protection suited to each body type. That way, safety is total.

Accepting your cycle becomes easier with the right tools. It helps avoid being left out of social or sports activities. It’s an instant boost of confidence for young girls. Discretion is key.

Summer becomes fun again for every teenage girl. They feel beautiful and protected with zero compromise on style.

Multilayer technology for total peace of mind in the water

But how does it really work inside? We break down the menstrual swimsuit for you to understand this textile feat!

The secret of waterproof, breathable membranes

The crotch area hides three ultra-thin technical layers.

The first fabric layer channels the liquid toward the absorbent core.

The second fabric layer stores menstrual flow without adding bulk.

Finally, the third, waterproof outer layer prevents any transfer to the outside of the swimsuit.

The fabrics are certified 100% OEKO-TEX® STANDARD 100 to guarantee the absence of harmful substances. This strict standard ensures safe protection for your body. It’s an essential safety guarantee for your skin. Moisture is wicked away while keeping the blood locked in. Your skin breathes and stays healthy throughout use. It’s cutting-edge technology serving your daily intimate care.

See our textile analysis report for full transparency. We detail every component of our protections. Science replaces chemicals. Your body will thank you for this healthy and effective choice.

A technical barrier that resists chlorine and salt

The fibers are treated to withstand external stress. Pool chlorine doesn’t damage Noa’s elasticity. Sea salt doesn’t eat away at the absorbent membranes either. Your one-piece period swimsuit keeps its original shape wash after wash.

Built-in UV protection helps preserve the colors. The sun won’t dull your swimsuit’s brightness. It’s a long-lasting investment for many summers to come.

The flexibility of the materials lets you move freely. The fabric doesn’t become rough after multiple swims. You keep the same comfort as on day one.

Louloucup selects high-quality textiles. Every seam is designed to last despite harsh summer conditions. Durability is guaranteed. Beach or pool, your one-piece period swimsuit will never let you down.

We’ll help you choose your future one-piece period swimsuit

To make the experience perfect, you need to choose the right style and absorbency. Here are our tips.

Matching absorption to the intensity of your period

Each flow requires an appropriate response to avoid unpleasant surprises. The Noa one-piece period swimsuit is ideal for light to medium flows. It absorbs the equivalent of about two regular tampons. It’s perfect for a relaxed half-day at the beach.

If your needs are greater, there are specific solutions. You can combine, as we advised earlier, swimsuit + cup. It’s absolute security for long swims. You’ll be able to swim for hours without a second thought. However, don’t forget, the cup should be emptied and rinsed every 4 to 6 hours ideally. This is important for your hygiene and health.


The key is to never feel limited by your cycle.


Choose according to your real needs. Your comfort depends on this initial, accurate assessment.

Recognizing the signs of saturation to avoid leaks

It’s vital to know when to change your one-piece period swimsuit. A feeling of heaviness or persistent dampness is a clear sign. If the fabric feels thicker at the crotch, you’re nearing its limit. Don’t wait for overflow.
On average, plan to change it every four to six hours. Of course, this varies according to your personal flow intensity. Stay attentive to your body’s signals.

To change your protection at the beach, bring a waterproof pouch to safely store your wet swimsuit.

A quick rinse with clear water is recommended after removal. It makes the final wash easier once you’re home.
Listening to yourself is essential. Planning ahead helps you stay calm all day long. For teens, using washable period protection is also a way to learn responsibility.

Why it’s worth doing a first test run at home before hitting the beach

We always recommend a relaxed trial run at home. The same goes for your first time using a period panty or a menstrual cup. Wear the one-piece period swimsuit in the shower to test how it reacts to water. Check that the elastics sit snugly against your wet skin. It’s reassuring before the big plunge.


Watch how the fabric absorbs water without swelling excessively. You’ll understand better how the multilayer technology works. It’s an excellent way to build confidence in your gear.


Don’t hesitate to check out our menstrual cycle guide to deepen your understanding of your body. Knowing yourself better means living your period better.
Adjust the straps well for optimal breast support. Comfort starts with a proper morphological fit.

Tested and approved? Ready? The ocean is waiting for you and your Noa. 😍

Bonus: how to care for your one-piece period swimsuit so it lasts for years?

Finally, here are our tips to keep your Louloucup one-piece period swimsuit your best friend for a long time.

Immediate rinsing and cold washing without fabric softener

Rinse your one-piece period swimsuit in cold water as soon as you get out of the water. This removes salt and chlorine that damage the fibers. Never use fabric softener when machine washing. This product clogs the absorbent pores of the fabric.

  • Wash it at a maximum of 30 degrees to preserve the waterproof membrane. A delicate cycle is best to maintain elasticity.
  • Use a regular detergent without fatty agents or glycerin. No fabric softener or bleach.
  • Air dry only.
  • Absolutely avoid the tumble dryer, which could damage the technical components.
  • Simply hang it to dry in the shade.

These simple steps will save your swimsuit. Durability starts with proper care.

You keep a natural silhouette and total freedom of movement, whether you’re swimming or relaxing on your towel. That’s the magic of Louloucup’s multilayer technology: powerful performance wrapped in a beautifully sleek design.

Is the Noa model suitable for teenagers and school swimming lessons?

It’s actually the ideal solution to boost their confidence! The Noa one-piece offers superior support and absolute discretion in the changing rooms, because it looks exactly like a regular swimsuit. It allows young girls to stop missing PE or swimming lessons because of their cycle.
By choosing a suitable model, teens forget about stain anxiety and can focus on their movements. It’s real freedom that transforms how they experience their period from their very first cycles.

What is the lifespan of a Louloucup period swimsuit?

Investing in a period swimsuit is both an eco-friendly and budget-friendly choice. Thanks to the quality of our OEKO-TEX®-certified fabrics, your swimsuit is designed to last between 5 and 10 years with proper care.
