Beach, pool, surfing, relaxing. With their Smoon menstrual swimsuit, they keep going without a second thought.
Offers valid only on the green color of the summer edition.
Choose the size based on your daughter's measurements, not her age (teenagers grow at different rates). Take her waist and hip measurements to the nearest centimeter.
If she falls between two ranges, rely on the hip measurement to decide (it determines support in the water). And if she is between two sizes, we recommend choosing the larger one for comfort.
If she exceeds the 15/16 years range, write to us: we will guide you to our equivalent adult cuts.

Three scenes you may have already experienced. With a Smoon menstrual swimsuit, she enjoys summer without any worries.
Before, she stayed on the bench once a month. Now, she dives with her class, and no one knows anything.
« She was worried about getting her period while swimming in the club. That's no longer a concern. »Anneclaire L., mom
No more calculating dates before swimming. She goes into the water when her friends do, and she comes out whenever she wants.
« Teenagers feel more comfortable and no longer feel left out. »Ingrid, mom, Hydriades teen
Does your period calendar fall right on vacation? That's no longer a reason to cut your swim short or postpone a diving lesson.
« My daughter could forget her period and have fun in the water, and that's priceless. »Caroline B., mom, Hydriades teen
Thirty seconds, three questions. We'll tell you which one to choose.
Three differences she feels from the very first swim.
Our patented membrane absorbs up to the equivalent of 4 tampons and remains effective in water. No leakage, no swelling, no stains on the towel. Smoon is an official supplier of the French Swimming Federation.
Cuts for teens aged 11/12 to 15/16, soft elastics, invisible finishes. No one sees the difference, and neither does she.
Recycled polyamide, Oeko-Tex certified, designed in Paris. Absorption maintained for at least 50 washes, equivalent to two to three seasons depending on use.
Hundreds of verified reviews on the teen collection. Average rating 4.4/5.
"My daughter could forget her period and have fun in the water, and that's priceless."
"First period on vacation at the sea for my 15-year-old daughter. The swimsuit allowed her to swim every day."
"She was worried about having her period while swimming in the club. That's no longer a concern."
Offerte
To store your wet swimsuit without it leaking in your bag. No more plastic, no more soggy towels, no more repacking.
The wet swimsuit stays where it is, in the pouch. The beach bag, the school bag, and the clean clothes stay dry.
Fits in a corner of a sports bag or backpack. Slides into a toiletry bag when traveling.
No more plastic bags to throw away after each swim. The pouch rinses, dries, and reopens. Summer after summer.
Three combined textile technologies. An absorbent membrane, a waterproof material, silicone seals. All designed to remain functional at all times in water.
We pulled out the calculator to reassure you. Over three summers, a Smoon menstrual swimsuit costs less than one summer’s worth of tampons.
Et chaque mois, le calcul « peut-elle se baigner aujourd'hui ? ».
Et la tranquillité. Toute la saison, sans plan B.
Before buying, here’s what moms ask us most often.
Our patented membrane captures the flow and holds it, even underwater. Your daughter swims, dives, comes out of the water: the panties remain dry to the touch on the outside. She doesn’t feel anything different from a regular swimsuit.
Four cuts to choose from according to your style and flow.
Brizo, one-piece, maximum coverage. Ideal for teens who swim at school or in a club, or for those who want a swimsuit ready to wear without worrying about the top.
Héliades, low-cut waist. For those who want to wear their usual swimsuit top and keep a classic cut.
Hydriades, high waist. Reassuring coverage, perfect for first periods or teens who want a wrapping swimsuit.
Leucosie, high waist with a central knot. For those who want a fashion detail without giving up protection.
If in doubt, the Smoon team responds by email within the day.
Up to 12 hours, the equivalent of two tampons. More than enough to cover a day at the beach, a swimming lesson, or a morning at the pool. Replace if the flow is very heavy.
One piece is enough for occasional swims. Three pieces is the most common choice for vacations: one she wears, one drying, one in the bag. Five pieces for camps, sports training, or long stays where a washing machine is not available.
Whatever the quantity, the waterproof pouch to store the wet swimsuit is included.
You have 60 days to try them, even in the water. If the fit doesn’t suit your daughter, you can return them for free and we will refund you with no questions asked. And if you’re unsure between two sizes, write to us and we’ll guide you before your purchase.
