    The Sorio Teen Period Bikini Bottoms Collection

    Period bikini bottoms designed for teen girls offer discreet and reliable protection during your period. This means your teen can enjoy the pool or the beach with peace of mind.

    Thanks to their absorbent layers designed to hold light to heavy menstrual flow both in and out of the water. They provide your teen with leak-proof protection throughout the day, removing the stress linked to periods.

    Reusable, hygienic and easy to care for, period bikini bottoms are the most eco-friendly and cost-effective solution on the market.

    In short, period bikini bottoms help your teen stay active and confident during water activities.

    Period bikini bottoms designed to appeal to teens

    A swimsuit is above all a fun seasonal purchase at the start of summer. That’s why we created a very varied range of period bikini bottoms for teens.

    Trendy colours:

    We’ve released our best-seller Eva in 3 colours:

    1. In black

    2. In blue

    3. In khaki

    With this choice of colors, your teen is sure to find her future period swim bottom.

    But Eva isn’t the only style available; our range of period bikini bottoms for teens includes different cuts to suit her style and preferences:

    • Naya: the high-waisted period swim bottom

    • Ava: on-trend with its white lines

    • Nina: a seamless second-skin bottom

    • Aria: the swim skirt, stylish and more covering

    With this wide choice of period bikini bottom styles, your teen can create beautiful mix-and-match looks with tops she already has in her wardrobe or fall for the matching tops :

    • Lya: the bikini top designed to support and cover her chest even during a game of beach volleyball.

    • Ava: completes the look of the matching bottom and enhances all her classic black bottoms.

    Color, a variety of cuts, and tops to complete the look—everything needed to perfect your teen’s period swimwear style.

    A period bikini bottom for better intimate comfort

    Giving your teen a period bikini bottom means giving her a menstrual solution that respects her privacy.

    For years, to swim during your period, we only had two options:

    1. Not swim

    2. Use tampons

    But in light of recent studies and cases of toxic shock syndrome triggered by tampons, that second option is no longer really viable..

    And beyond that, there’s the lack of practicality, the discomfort, and the constant fear of the string slipping out of the swimsuit.

    Period bikini bottoms, on the other hand, offer long-lasting protection, which means:

    • No need to change during a beach day

    • No risk of toxic shock

    • No string slipping out

    • No leaks

    • No odour

    • No marks

    • No hassle

    But how is that possible? Thanks to their 4-layer absorbent technology.

    The first layer is a hypoallergenic lining that lets blood pass through while keeping her dry all day long.

    The second layer lets blood pass to the lower layer without letting water through, which guarantees leak-proof protection.

    The third layer captures and channels blood for 8 hours. This area has an absorbency capacity equivalent to 3 tampons.

    The last layer is the outer waterproof fabric treated against UV rays and chlorine. This layer prevents water from seeping in from the outside, and its treatments help the swimsuits last longer.

    Thanks to the absorbent technology in period bikini bottoms, your teen can feel confident all day long—and for the next 5 years.

    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.

    They tried it, approved it, and adopted it

      The swimsuit is very pretty and good quality. My daughter tried it on but hasn't tested it yet.
      Shipping is fast.
      Thank you Sorio!!!

      I was pleasantly surprised, and it was very useful for my daughter during her week at camp. She was able to enjoy the pool with no worries, despite her first period. It was an excellent purchase.

    • 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 about leaks, but no, it held up perfectly, just as described.

      09/15/2026

    • Valérie D.

      My daughter is thrilled! The shorts fit perfectly. She was able to make the most of her vacation and do all the water activities planned, including jet skiing, canoeing, and diving!

      08/11/2026

    • Claire K.

      Very happy and satisfied with my purchase! I wore it for a whole afternoon, alternating between sunbathing, swimming, and walking, and had no leaks at all. As I have a fairly heavy flow, I recommend it 100%.

      08/10/2026

    • Melanie W.

      First order for my daughter and she's thrilled that she can go swimming during the heat wave without any worries, perfect

    Frequently asked questions

    How do I choose period swim bottoms for my teen?

    It's pretty simple. You need to know her swimwear size (a size guide is available below the size selector) and her menstrual flow.

    Measuring your teen's menstrual flow can be tricky, which is why we created a guide to help you choose the ideal swimwear.

    At what age can my teen start wearing period swimwear?

    There's no minimum age for wearing period swimwear.

    From her very first period, your teen can use suitable swimwear. You just need to choose the right size and absorption level for her needs.

    Can my teen swim in period swimwear without risk of leaks?

    Fear of leaks is common, but period swimwear carries less risk of leaks than tampons.

    Its absorption technology captures only blood, not water, with no discomfort and no ballooning. The swimwear follows the body's movements perfectly, which prevents leaks.

    Your teen can swim with peace of mind during her period with Sorio period swimwear.

    Is there a difference in absorption between heavy flow and regular period swimwear?

    Yes, there's a difference in absorption between swimwear for medium flow (regular) and swimwear for heavy flow.

    Regular period swimwear absorbs the equivalent of 3 tampons, while heavy flow period swimwear offers extra absorption capacity.

    Either way, your teen gets 8 hours of peace of mind, as long as she chooses the style that matches her flow. On the heaviest days, regular swimwear will reach its limit sooner and should be changed about every 4 hours.

    Not sure how to gauge her flow? Our guide will help you figure it out.

    Can my teen wear a one-piece period swimsuit in competitions?

    Yes, as long as the cut of the swimsuit is suited to competitive swimming, like the Lola style.

    All your teen has to do is go for gold!

    How long does teen period swimwear last?

    Teen period swimwear has a lifespan of at least 5 years.

    With proper care, it can last even longer.

    In particular, we recommend placing it in a laundry bag when washing, avoiding the dryer, and following the care instructions to extend its life by a few years.

    Why choose Sorio for my daughter's period swimwear?

    Since the very beginning, Sorio has designed period swimwear made for teens. Our range has been developed over several years with one clear goal: freeing teens from the constraints of their period.

    Our experience in period swimwear and the thousands of happy young customers make us the No. 1 brand of period swimwear for teens.

    We keep improving our products every day to give them comfort, security, and freedom.

    Where can I find Sorio period swimwear for teens?

    Sorio period swimwear for teens is available in several places.

    You can buy it on our website, on Amazon, or in store at Decathlon starting April 2026 and at our partner pharmacies.
