Go and explore the period bikini bottom collection to find the swimsuit that will stay with you for the next 5 years.
To choose the ideal period bikini bottom, two criteria are essential:
your menstrual flow
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.
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.
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.

Your turn!
Can I swim without a tampon, even when I'm playing sports?
Yes, absolutely.
Sorio period swimwear is designed to let you swim without a tampon, including during sports.
Thanks to its built-in absorption technology, period swimwear effectively absorbs your menstrual flow with no need for extra period products.
Our period swimwear moves with you, comfortably. Unlike tampons, which can feel uncomfortable inside when you move and carry a risk of leaks or swelling, there's no string slipping out of your swimwear 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 extra absorption, so you can swim and play sports with peace of mind, no tampon needed.
Which is more effective: period swim bottoms or a one-piece period swimwear?
At Sorio, there's no difference.
All our period swimwear is designed with the same absorption technology.
Whether you choose period swim bottoms or a one-piece period swimwear, you get the same absorption capacity.
If you have a heavy menstrual flow, we created a specific range of period swimwear designed for that need.
You'll find both bottoms and one-pieces there.
Can I wear period swimwear on heavy flow days?
Yes, absolutely, as long as you choose period swimwear specially designed for heavy flow.
With its extra absorption capacity, it gives you suitable, reliable protection for 8 hours, with no risk of leaks.
"Regular" period swimwear can also be worn, but it will reach its absorption limit sooner. In that case, you'll need to change it more often, ideally every 4 hours, to stay fully protected and avoid any risk of leaks.
