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 bikini bottoms

Sorio’s period bikini bottom collection

Our range of period bikini bottoms has been designed to support you in everyday life without adding any extra constraints.

You can enjoy your swims, your holidays, or your moments of relaxation, even during your period, with complete peace of mind.

Each style replaces a traditional bikini bottom without looking like period swimwear because its absorbent layer is so discreet. The cuts, fabrics, and finishes are designed to stay discreet and elegant without raising the slightest suspicion.

Thanks to their washable, absorbent technology, Sorio period bikini bottoms can simply be machine washed.

No hand washing, no complicated routine: your swimwear adapts to your lifestyle.

In short, this collection was designed to adapt to you, with timeless cuts created to blend naturally into your wardrobe, season after season.

What period bikini bottom styles does Sorio offer?

Our range of period bikini bottoms is very diverse, from tangas to high-waisted styles and even swim skirts. This way, every woman can find the style that suits her, according to her preferences, comfort, and desired level of coverage.

  • Classic bottoms:

    • Eva, the iconic black bikini bottom, is also available in blue and khaki. This style is also available in a version designed for heavy flow.

    • Nina, a second-skin-effect bottom, ideal if you want to wear it on its own or under your favorite swim bottom without disrupting your swimwear set.

  • Tanga bottoms:

    • Mila, with its high-cut shape, enhances your curves elegantly while still providing the protection you need during your period.

  • High-waisted bottoms:

Go and explore the period bikini bottom collection to find the swimsuit that will stay with you for the next 5 years.

How to choose your period bikini bottom?

To choose the ideal period bikini bottom, two criteria are essential:

  1. your menstrual flow

  2. your body shape

Always start by identifying a style suited to your flow.

If the swimsuit’s absorbency is too low for your flow, you will need to alter your period bikini bottom several times during the day.

On the other hand, a bikini bottom well suited to your menstrual flow can give you up to 8 hours of peace of mind without stress or discomfort.

If you find it difficult to assess your flow, we created a dedicated guide to help you determine it

Once you know your flow, choose a period bikini bottom cut that truly flatters you:

  • A-shaped body: Your hips are your asset.
    Choose high-cut styles, such as the tanga style or the second-skin-effect style, to enhance your hips.

  • V-shaped body: Your shoulders are broader.
    Balance your silhouette with a high-waisted swim bottom or a swim skirt, which will add volume around your hips.

  • H-shaped body: Your waist is not very defined.
    A high-waisted bottom will help structure your silhouette by creating a waistline.

  • X-shaped body: Everything suits you!
    Your silhouette is already well balanced, so you can absolutely wear anything.

  • O-shaped body: You embrace your curves,
    And to enhance them, choose a high-waisted bottom, or a one-piece style.

If you do not know your body shape, we also created a detailed guide to help you better understand your silhouette and choose the style best suited to your body shape.

Period bikini bottoms that fit seamlessly into your daily life

Sorio period bikini bottoms feature washable absorbent technology, designed to last and make your life easier.

In practical terms:

No hand washing, no restrictive steps, simply a machine wash with your usual laundry.

As part of its eco-conscious approach, Sorio designed a textile technology made to last.

Each bikini bottom is designed to be used for at least five years.

That means:

  • five years without buying tampons or disposable products

  • five years of peace of mind

  • hundreds of euros saved

  • thousands of items of waste avoided

Because what would be the point of reusable period swimwear if you had to replace it after 2 years?

And to do even more for women’s daily lives, Sorio does not just offer you effective period swimwear.

We are also involved with associations that support women in their daily lives, notably through:

  • donating period swimwear to UCRM, an association that helps women in vulnerable situations.

  • donations to Keep a breast, an association working to inform people and reduce the impact of breast cancer around the world.

The period swimsuit is not just a revolution for your period; it is also a concrete gesture for the planet and the people who live on it.

Why fall for a period bikini bottom?

Switching to period swimwear is an important step, and it is normal for it to feel a little intimidating at first.

That is exactly why Sorio designed this range of period bikini bottoms.

The cuts follow the codes of classic swimwear to allow for a smooth transition without disrupting your clothes.

By choosing a Sorio period bikini bottom, you can create beautiful mix-and-match looks with your favorite tops or pair it with the Lya top.

Thanks to ultra-thin absorbent technology, your swimsuit is completely indistinguishable from a traditional swimsuit.

Bikini bottoms are also highly versatile, making them an excellent option for a first-period swimsuit.

You can wear them for a swim, but also under shorts before heading to the beach, for a spa massage, or at a beach party.

Switching to period swimwear means choosing a reliable, discreet, and durable companion that goes everywhere with you during your period.

Frequently asked questions

How does a women’s period swimwear absorb my period?

Women’s period swimwear is designed with 4-layer absorbent technology that captures and retains your menstrual flow while keeping you dry.

The absorbent technology is made up of:

  1. a hypoallergenic lining that respects your intimate flora
  2. a honeycomb layer that lets blood through, but not water
  3. an absorbent fabric made from natural bamboo fibres that absorbs and retains blood
  4. a waterproof layer that prevents water from seeping in and an anti-chlorine and anti-UV treatment, so your swimsuit lasts longer

This technology guarantees you a leak-free, worry-free day.

How do you choose your women’s period swimwear?

Choosing your period swimwear couldn’t be easier:

  1. Choose a style suited to your size
    A size guide is available for each swimwear to help you make the right choice

  2. Check that the absorbency matches your menstrual flow
    If you don’t know whether your flow is medium or heavy, we created a guide to help you assess it

Your turn!

Can you swim without a tampon, even when doing sport?

Yes, absolutely.

Sorio period swimwear is designed to let you swim without a tampon, including during sports activities.

Thanks to their integrated absorbent technology, period swimwear effectively absorbs your menstrual flow without requiring any additional period protection. 

Our period swimwear moves with you, without discomfort. Unlike tampons, which can cause internal discomfort during movement, a risk of leaks or swelling, there’s no string slipping out of the swimsuit and no risk of toxic shock syndrome. 

You can swim, move, and enjoy your water activity with complete peace of mind.

And if you have a heavy menstrual flow, Sorio also offers period swimwear with enhanced absorbency, allowing you to swim and exercise with complete peace of mind, without a tampon.

Which is more effective: a period bikini bottom or a one-piece period swimsuit?

At Sorio, there’s no difference.

All our period swimwear is designed with the same absorbent technology.

Whether you choose a period bikini bottom or a one-piece period swimsuit, you benefit from the same absorbency capacity.

If you have a heavy menstrual flow, we created a specific range of period swimwear adapted to this need.

You’ll find both bikini bottoms and one-piece swimsuits there.

Can you wear a period swimwear on heavy-flow days?

Yes, it’s absolutely possible, provided you choose period swimwear specifically designed for heavy flows.

Thanks to its enhanced absorbency, it will provide reliable, suitable protection for 8 hours, with no risk of leaks.

A “classic” period swimwear can also be used, but it will reach its absorbency limit more quickly. In that case, it will need to be changed more often, ideally every 4 hours, to stay fully protected and avoid any risk of leaks.

Why choose the Sorio brand over another when buying my period swimwear?

At Sorio, we design period swimwear for active women who want to keep swimming, even during their period.

For several years, we have been developing period swimwear that combines support, comfort, and effectiveness to meet the demands of movement and effort in the water.

Our period swimwear is designed to:

  1. provide excellent support, ideal for sport
  2. effectively absorb menstrual flow without a tampon
  3. remain discreet, even in motion
  4. avoid any discomfort throughout the day

Our swimsuits have already supported and won over thousands of women, and every day we continue improving our products to offer you safety, freedom, and peace of mind, in and out of the water.

Choosing Sorio means choosing reliable period swimwear, designed to keep up with your pace, not slow it down.
