    Sorio’s collection of heavy flow period swimwear for women

    At Sorio, we want every woman to feel free to fully enjoy moments of swimming during her period. That’s why we created this new range of period swimwear designed for women with heavy menstrual flow.

    Why choose a swimsuit for heavy flow rather than a standard absorbency swimsuit?

    Like standard absorbency period swimwear, heavy flow period swimwear gives you 8 hours of protection.

    It has an absorbency capacity equivalent to 3 to 4 super-absorbent tampons.

    Whereas “classic” period swimwear has an absorbency capacity equivalent to 3 regular tampons. These swimsuits are suitable for women with light to moderate flow, but not for women with heavy periods.

    If you have heavy periods, a “classic” period swimsuit will only give you a few short hours of absorbency, without the peace of mind that should come with it.

    You’ll be under constant stress, worried that the swimsuit will quickly reach its maximum absorbency and, as soon as you feel your flow starting, you’ll be afraid of leaking.

    With a period swimsuit designed for heavy flow, you can forget that fear and enjoy the same leak-proof protection as women with a lighter flow.

    You can also choose a heavy flow period swimsuit even if your flow is moderate.

    But why do that? Quite simply to extend how long you can wear your period swimsuit. Because its absorbency capacity is higher, your period will be absorbed for longer.

    However, be careful, because prolonged wear (more than 8 hours) of menstrual protection can cause intimate discomfort. So make sure this remains occasional and is accompanied by impeccable intimate hygiene.

    How do you care for a heavy flow period swimsuit?

    Caring for your heavy flow period swimsuit is quite simple, since Sorio period swimwear is machine washable!

    When you get out of the water, rinse your swimsuit in clean water.

    If you’re at the beach, pool or spa and prefer to rinse it once you get home, that’s absolutely possible: simply place it in a waterproof pouch for transport.

    Then put your swimsuit in the washing machine with your laundry or on its own, add your detergent, but above all no fabric softener!

    Run your washing machine at 30°C, preferably on a delicate cycle.

    Once washed, take it out and let it air dry until completely dry. Never put it in the tumble dryer, to preserve its effectiveness and absorbency capacity.

    You don’t need to do anything else!

    Heavy flow period swimwear is easy to use so it doesn’t add to your mental load.

    Wear it, enjoy it, wash it, let it dry… and dive back in!

    Sorio puts women first!

    No woman should ever be left out — that’s Sorio’s philosophy!

    That’s why, in addition to offering a sustainable menstrual solution for all women and teens, we wanted to extend our commitment by:

    1. Within our teams (mostly women), by introducing menstrual remote work.

    2. Supporting the Toulouse-based association UCRM which helps women in vulnerable situations.

    How does it work?

    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.

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

      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!

      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!

      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.

    • 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.

    • 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
      Not sure whether your flow is medium or heavy? We created a guide to help you figure it out

    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.
