How does the Sorio period swimwear work?

Sorio has developed innovative absorbent technology to guarantee safe swimming for its customers. 

Period protection is integrated directly into your period swimsuit, designed to absorb blood, but not water. 

This protection is made up of 4 layers: 

  • 1 Hypoallergenic lining: respects your intimate area
  • 1 Honeycomb layer: lets blood pass through
  • 1 Absorbent fabric: retains menstrual flow
  • 1 Outer fabric: waterproof and treated against chlorine & UV rays

Collection: Period Swimwear for Teens

Sorio’s period swimwear collection for teens

Your teen should never have to miss out on a swim with friends, skip a swimming lesson or give up an activity during the holidays because of her period. First periods are often unpredictable, both in terms of flow and duration, and can quickly become a source of stress.

So that young girls no longer hesitate at the poolside, we created a period swimwear collection specially designed for teens.

At Sorio, we support teenage girls so they can experience their menstrual cycle with complete freedom, calmly, and without ever letting their period hold them back.

Why did we create swimwear for teens?

Teen girls have very specific needs: their bodies are changing, their menstrual cycle is settling in, and it is essential to offer them a solution that is truly suited to this time of transition.

A body shape that is constantly changing

Puberty is a time when the body shape changes quickly: in-between sizes, hips beginning to take shape, breasts developing… Teen girls gradually move on from children’s sections, but still do not fully match adult cuts.

It is precisely to meet the needs of this changing body shape that we designed a period swimwear collection specially created for teens, with swimsuits that fit perfectly, without squeezing or slipping. Every cut has been designed to offer comfort, support and confidence.

To help you choose the ideal style for your teen, we created detailed size guides for each swimsuit, tailored to teenage girls’ specific measurements.

First periods: often a stressful time

During the first few years, periods can be very irregular, both in length and intensity. It can therefore be difficult to determine your teen’s actual menstrual flow and choose the most suitable period swimsuit.

To ensure effective protection during swimming lessons, outings with friends or beach days, we recommend basing your choice on her heaviest flow.

Don’t worry, we created a guide to help you easily calculate your teen’s menstrual flow. Once you know her flow, all you need to do is choose a suitable swimsuit.

On each product page, you will find clear information distinguishing moderate flow from heavy flow.

Our swimsuits provide them with reliable leak-proof protection, even while moving. They will never again have to worry about a tampon string showing or the risks associated with toxic shock. They can swim, play, sunbathe and enjoy themselves fully, with complete peace of mind.

Period swimwear designed for teens’ needs

Because every teen is unique, Sorio offers a complete range of period swimwear designed to suit all their preferences and all their activities.

  • For sunbathing freely: the period bikini
    Discover our Eva, Ava and Nina styles. Discreet and versatile, they make it easy to create beautiful mix & match looks so you can stay stylish, even on your period.

  • For swimming or sports activities: the one-piece swimsuit
    Our Lola style, featuring a racerback, is specially designed for swimming. Perfect for PE lessons or for pool lovers.

  • For those who want more coverage:
    Three styles offer more coverage while staying elegant :

Each style features Sorio’s leak-proof technology, which is absorbent, breathable and ultra-thin, and cannot be distinguished from a traditional swimsuit.

Sorio frees teens from period-related constraints, and more!

Beyond offering period swimwear suited to teenage girls, we are committed to supporting them through a broader approach focused on information, prevention and well-being.

We already provide educational resources, such as:

  • An e-book to better understand the menstrual cycle.

  • A fun booklet to help her get familiar with her first periods.

  • A blog full of articles and advice to help her experience the arrival of her first periods with peace of mind.

We also take action on the ground by supporting Coral Guardian and Wings for the ocean, associations whose mission is to protect the oceans, so your teen can enjoy their beauty for life.

At Sorio, we want to help every teen grow up with freedom, confidence and comfort, during her period… and every day.

Frequently asked questions

How do I choose a period bikini bottom for my teen? 

It’s quite simple. You need to know her swimsuit size (a size guide is available below the size selector) and her menstrual flow. 

Assessing your teen’s menstrual flow can be complicated, which is why we created a guide to help you choose the ideal swimsuit.

From what age can my teen wear a period swimsuit?

There is no minimum age for wearing a period swimsuit.

From her very first period, your teen can use a suitable swimsuit. You simply need to choose the right size and absorption level to match her needs.

Can my teen swim in a period swimsuit without any risk of leaks? 

Worrying about leaks is common, but period swimwear carries less risk of leaking than tampons.

Their absorbent technology captures only blood and not water, without discomfort or swelling. The swimsuit follows the body’s movements perfectly, which prevents leaks.

Your teen will be able to swim with confidence during her period with Sorio period swimwear.

Is there a difference in absorption between a heavy-flow period swimsuit and a classic period swimsuit?

Yes, there is a difference in absorption between a swimsuit for moderate flow (classic) and one for heavy flow. 

Heavy-flow period swimwear has a higher absorbency capacity to guarantee you 8 hours of peace of mind. 

A classic period swimsuit has an absorbency equivalent to 3 regular tampons, while a heavy-flow period swimsuit has an absorbency equivalent to 3 to 4 super-absorbent tampons. 

Both options offer you a minimum of 8 hours of peace of mind. 

Can my teen wear a one-piece period swimsuit in competition?

Yes, she can, provided that the cut of the swimsuit is suitable for competitive swimming, like the Lola model. 

Your teen will just have to go for the gold medal!

How long does a period swimsuit for teens last? 

A period swimsuit for teens has a minimum lifespan of 5 years.

With proper care, this lifespan can even be extended. 

We particularly recommend placing it in a fabric pouch during washing, avoiding the tumble dryer, and following the care instructions to extend its lifespan by a few more years.
