THE RÉJEANNE PATENT: A UNIQUE, INVISIBLE AND LEAK-PROOF TECHNOLOGY
Réjeanne: The First Patented French Period Lingerie Brand
Launched in 2018, Réjeanne is the first French patented period underwear brand. After years of collaboration with textile engineers, French experts and workshops predominantly based in France, we have created the perfect period underwear that doesn't compromise on function or style. Designed with a patented, invisible protective layer, made from organic cotton, our underwear offers superior comfort, reliability and style, all whilst eliminating the risk of toxic shock.
Lightweight and ultra-absorbent, (holding the equivalent of one to seven tampons, depending on the model), Réjeanne's period underwear provides soft, comfortable protection throughout your period.
Developed in France, leveraging the expertise of workshops that collaborate with leading lingerie brands, as well as French experts in fabrics and patents, our technology is based on a unique blend of three materials.
1. Moisture-Wicking Organic Cotton
A few millimeters of very soft, breathable, moisture-wicking fabric, made from organic cotton.
2. Absorbent Tencel
Ultra-thin, eco-friendly Tencel that absorbs flow rapidly and continuously.
3. Leak-proof PUL Layer
A waterproof and breathable membrane that locks in flow, providing leak-proof protection for up to 12 hours at a time.

Period products represent a significant expense in a woman's life. On average, we spend around £10 per month on single use period products, adding up to about £600 over the course of five years (not including replacing stained pants or pyjamas). With Réjeanne period underwear, there's no need to buy new products every month or throw away dozens of tampons and pads with each cycle. An added bonus? No risk of toxic shock, meaning less anxiety and no more waking up in the middle of the night!

Absorbs the equivalent of 1 to 2 tampons.
Perfect for light flow, whether at the start or end of your cycle, or as a backup to your usual protection.
They can absorb the equivalent of 3 to 7 tampons.
They are designed to be worn on days when your flow is heavier (usually 2nd or 3rd day of the cycle) and at night for added peace of mind.
