Frequently asked questions

Your questions, answered

Leakproofing, size, cut, care: everything you need to know before choosing your period swimsuit.

How does a Smoon menstrual swimsuit work?

It combines a very snug fit, silicone anti-leak seals, an absorbent fabric and a waterproof membrane: it absorbs the equivalent of 4 tampons, for up to 12 hours, with no other protection. It doesn't swell once wet and leaves no mark on your towel. It works like our menstrual panties, adapted to the water.

Which menstrual swimsuit should I choose?

All our swimwear absorbs the equivalent of 4 tampons, so the choice comes down to the cut. The one-piece swimsuit covers the most, the bikini bottom is worn with the top of your choice, and the Cyrène swim boyshort, which covers even more, is made for surfing or paddleboarding.

What size menstrual swimsuit should I choose?

Go by your measurements rather than your usual size: the swimsuit is worn very snug, which is what keeps it leak-proof. Women's styles run from XS/34 to XXL/44, and the Doris top from XS/34 to XL/42. The measurements are in the size guide.

How do you care for a menstrual swimsuit?

Rinse it in clear water after swimming, then wash it by hand or in the machine, cold or at 30 °C, without oil-based soap (Marseille, Aleppo). Let it air dry, never in the tumble dryer. Its fabrics are resistant to chlorine and salt water.

Where are Smoon swimsuits made?

Their fabrics are knitted and dyed in France and Italy, then the swimsuits are made in Tunisia. They are OEKO-TEX® STANDARD 100 certified (certificate no. CQ 1285/2), and their outer fabric contains 78% recycled polyamide.

Can you wear a menstrual swimsuit in a hot tub, sauna or steam room?

We advise against it: in a hot tub above 30 °C, a sauna or a steam room, the heat can undo the heat bonding that holds the fabrics together and damage the swimsuit. Pools and the sea are not a problem: its fabrics are resistant to chlorine and salt water.

How does a menstrual swimsuit work?

A menstrual swimsuit is worn on its own, with no tampon or cup: its brief section combines an absorbent fabric and a waterproof membrane, and silicone anti-leak seals close around the thighs. At Smoon, each style absorbs the equivalent of 4 tampons, for up to 12 hours, at the pool or at the sea.

The range is chosen by cut first. The one-piece swimsuits cover the most: Naiades and Ourania for swimming, Néréides and Clio for the beach. The bikini bottoms Héléades, Ligie and Océanides are worn with the top of your choice, such as the Doris top, and the Cyrène swim boyshort is made for surfing or paddleboarding. For teens, the teen swimsuits run from 11/12 to 15/16.

The swimsuit is worn very snug: choose it by your measurements, using the size guide. After swimming, rinse it in clear water, then wash it at 30 °C maximum, without oil-based soap or tumble drying. Its fabrics, knitted in France and Italy and OEKO-TEX® STANDARD 100 certified, are resistant to chlorine and salt water. Avoid hot tubs above 30 °C, saunas and steam rooms, however: the heat can undo the heat bonding of the fabrics.
