Details

The panties that grows with her.

Designed to support teenagers from their very first period through the end of adolescence, the One Size Menstrual Underwear – Medium Flow adapts to every body shape from ages 10 to 16, thanks to an innovative ultra-stretch fabric.

🤫 Its secret? MemoryStretch yarn: an ultra-fine shape-memory polyamide, able to follow every change in the body while returning to its original form. Long-lasting elasticity, without deformation or loosening, even after many wears.

Equipped with our 3-layer absorbent technology, it provides reliable protection for up to 12 hours — with no dampness, no odor, and no leaks — for a flow equivalent to 2 tampons.

And because it’s seamless, it stays completely invisible under clothing — for optimal comfort, in total discretion.

No more size changes every 6 months: one pair of underwear that lasts, and reassures.

Bonjour, très déçue , ma fille l'a porté 1h30 et s'est retrouvée avec le pantalon complètement taché, elle n'ose plus les porter

Bonne matière, condortable, taille parfaitement et s'adapte à la morphologie de l'ado mais malheureusement des fuites à plusieurs reprises avec un flux moyen.

Le seul bémol de cette culotte est le fait qu'elle mette du temps a sécher.
Mais sinon ces culottes sont extrêmement confortables (elles s’adaptent à la forme du ventre sans le comprimer) , elles ont l'air solides et sont très discrètes.
Merci beaucoup, pour ce superbe produit. :-)
