Your period should never keep you from a beach day or a swim in the pool.
That’s why we created our collection of period bikini bottoms, designed for women and teens who want comfort, protection, and style with total freedom to swim anytime.
Our period-proof bikini bottoms feature four ultra-thin technical layers that discreetly channel and absorb your flow:
A hypoallergenic layer that stays soft and gentle on your skin.
A micro-perforated barrier that lets blood pass through and nothing else.
An absorbent core that locks in menstrual flow and prevents leaks.
A waterproof outer layer resistant to water, chlorine, and UV rays.
The result?
Four super-thin layers that keep you protected, invisible, and confident even in the water.
So you can swim, tan, or move freely without worrying about your period.
Absolutely.
Our swimsuits are lab-tested and real-life approved to offer reliable, discreet protection, whether you’re swimming, lounging, or walking along the beach.
Want proof?

Our period bikini bottoms come in different absorbency levels to fit your needs:
Light to moderate flow: Choose our Classic model (equivalent to about 3 tampons).
Heavy flow: Go for our High-absorbency model no extra protection needed for all-day peace of mind.
And because every body matters, we’ve also designed styles just for teens, helping young girls discover a sustainable, comfortable alternative from their very first period.
It’s super easy!
Store it in a waterproof pouch after swimming.
Rinse with cold water when you get home.
Machine wash at 30°C (86°F) with mild detergent.
Air dry naturally: no dryer, no softener.
And that’s it!
Your Sorio bikini bottom is ready for your next adventure beach, pool, or beyond.
Our period swimwear collection is designed to help you enjoy every aquatic activity without stress, leaks, or discomfort.
With Sorio, experience the perfect balance of confidence, comfort, and elegance, no matter where your cycle takes you.
Swim freely even on 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.
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:
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.
