    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.

    The Sorio period bikini bottom range:

    • Classic bottoms:

      • Eva, the iconic black bikini bottom, is also available in 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:

      • Naya: a sleek, timeless classic that covers the stomach and helps conceal period-related bloating.

      • Nola: a more playful version with its crossed strap detail at the back, combining support and originality.

    • The swim skirt:

      • Aria : ideal for women looking for coverage and elegance.

    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.

    How does it work?

    Video
    1. The honeycomb layer

      Keeps you feeling dry. This honeycomb layer lets blood pass through to the layers below. It is also hypoallergenic and antibacterial.

    2. The absorbent fabric

      A technical absorbent layer that captures and channels blood. Offers high absorption capacity.

    3. Reinforced FlowLock waterproof membrane

      Keeps water and blood from mixing. This protection is leakproof.
      Blood stays trapped in the swimwear and water can't get in.

    • Juliet C.

      Beautiful swimsuit, I love the shape! The absorbent part is quite thin, so it's discreet!

    • Myriam C.

      This swimsuit saved my vacation in the Canary Islands. When I realized I'd have my period during my trip, I ordered it a few days before leaving and received it within 48 hours.
      Absolutely delighted with the design and how well it works: no bulk and no diaper effect!!!!!
      A wonderful alternative to tampons, safer and more comfortable.
      One of my best purchases of 2026!

      08/28/2026

    • Giulia M.

      If only they'd invented this sooner, I'd have been spared years of misery! This swimsuit is without a doubt the best purchase of my summer. The quality of the fabric and seams is incredible. I bought two so I could change throughout the day and always stay dry. I took my exact size and the fit is perfect! I only have compliments, I love them!

      07/24/2025

    • Nune M.

      I'd buy it again without hesitation. I recommend it to everyone. I wore it for four days on vacation and was really very happy with it. At first I was skeptical and worried there would be leaks, but no, it held up perfectly, just as described.

      09/15/2026

    • Maria M.

      Comfort and style. Since my periods aren't very heavy, I forgot that I had to change every time I went in the water or checked my cycle. It gave me so much confidence; I even forgot I had my period. Plus, it fits me perfectly and you'd never guess it's a special bikini.

      08/28/2026

    • Sara V.

      Amazing! It works so well! I wore it for 6 hours straight with no problems at all.

    Frequently asked questions

    How does women's period swimwear absorb my period?

    Women's period swimwear is designed with a 4-layer absorption technology that captures and holds your menstrual flow while keeping you dry.

    The absorption 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 fibers that absorbs and holds blood
    4. a waterproof layer that keeps water out, plus an anti-chlorine and UV-protective treatment so your swimwear lasts longer

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

    How do I choose my women's period swimwear?

    Choosing your period swimwear couldn't be easier:

    1. Choose a style in your size
      Each swimwear style has a size guide to help you make the right choice
    2. Make sure the absorption capacity matches your menstrual flow

    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.

    Why choose Sorio over another brand for my period swimwear?

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

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

    Our period swimwear is designed to:

    1. provide excellent support, ideal for sports
    2. effectively absorb menstrual flow without a tampon
    3. stay discreet, even when you move
    4. avoid any discomfort throughout the day

    Our swimwear has already supported and won over thousands of women, and we keep improving our products every day to give you security, freedom, and peace of mind, in and out of the water.

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

    Where can I buy Sorio women's period swimwear?

    You can buy your period swimwear online or in stores.

    Find our women's period swimwear on Amazon, in Decathlon stores starting April 2026, or at our partner pharmacies.

    Please note: the full range of Sorio period swimwear is only available on our website. Our partners carry capsule collections.
