    Sorio’s collection of heavy flow period swimwear for teens

    Adolescence marks the arrival of first periods, often accompanied by worry, discomfort, and sometimes giving things up: avoiding the pool, turning down a trip to the beach, constantly monitoring your flow…

    At Sorio, our mission is to help teens experience this time more positively: with more peace of mind, without pressure or constraints.

    Thanks to our period swimwear, there’s no longer any need for tampons or compromises.

    Freeing teens from tampons means offering them a world where embarrassment, discomfort, toxic shock, and teasing from classmates no longer exist. Making way for a world of possibilities where their period will never hold them back!

    And to meet the needs of young girls with heavy periods, we have also developed a range of period swimwear for teens specially designed for heavy flow to guarantee them protection, comfort, and discretion in all circumstances.

    Why choose swimwear for heavy flow rather than a standard absorbency swimwear for your teen?

    Heavy-flow period swimwear for teens offers enhanced menstrual protection, ideal for supporting periods that can be irregular or heavier during the first years of menstruation.

    Their high absorbency capacity is equivalent to 3 to 4 super-absorbent tampons, providing up to 8 hours of security and peace of mind, whether your teen is swimming, playing, or sunbathing.

    Unlike traditional period swimwear styles, designed for light to medium flow, these period swimwear, specially designed for heavy flow, provide much more reliable protection. They spare your teen the stress of leaks, frequent changes of protection, or the discomfort and risks associated with tampons.

    That way, she no longer has to focus on her period but simply on enjoying the beach, the pool, her holidays, or a school trip without constraints.

    Choosing heavy-flow-period swimwear for teens also means choosing greater peace of mind, even when the flow is moderate. Thanks to its higher absorbency level, your teenager can keep her swimwear on longer with confidence.

    However, prolonged wear of menstrual protection (more than 8 hours) can cause intimate discomfort. So make sure your teen maintains good intimate hygiene and that prolonged wear remains occasional rather than routine.

    How do you care for Sorio heavy-flow period swimwear?

    All our Sorio heavy flow period swimwear styles are machine washable. This is ideal for parents who don’t have time to hand wash laundry, as well as for teens learning to do their first load of washing.

    After swimming, your teen simply needs to slip her period swimwear into a waterproof pouch to avoid getting her beach or pool bag wet or stained.

    Once back home, rinse it in clean water, then put it in the washing machine, on its own or with the rest of the laundry.

    Use your usual detergent, but no fabric softener, to preserve the swimwear’s absorbency.

    A 30 °C delicate wash is enough.

    Then simply leave the swimwear to air dry. It should never go in the tumble dryer if you want to preserve all its effectiveness and durability.

    And that’s it. No complicated washing, no extra mental load:

    Your teen uses it, washes it, lets it dry… and can enjoy it again with complete peace of mind.

    Sorio supports teens for period freedom!

    Adolescence is a time of change, which is why we want to help you as much as possible to support your teen so she can better understand and feel more prepared for her period.

    To do this, we regularly publish articles about periods to answer all her questions.

    But we don’t stop there! We have created:

    • 1 e-book to help her understand her menstrual cycle

    • 1 book to help her get to know her first period in a fun way

    These guides, tips, and advice can help you start the conversation or give her answers to questions she doesn’t dare ask you.

    First periods and everything that comes with them can be unsettling for your teen, so patience and kindness are essential to support her through this transition.

    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.

      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.

      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.

      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!

    • 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%.

    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.
