THE RÉJEANNE PATENT: UNIQUE INVISIBLE, LEAKPROOF TECHNOLOGY
Réjeanne became the first French patented period underwear brand in 2018.
For several years, we worked alongside textile engineers, French experts, and specialised manufacturing ateliers — particularly in France — to create the perfect period underwear with no compromises. The result: a patented, invisible protective technology combined with organic cotton, for period underwear that is more comfortable, more reliable, more beautiful, and with no risk of toxic shock syndrome.
Lightweight and ultra-absorbent — holding the equivalent of one to seven tampons depending on the style — Réjeanne period underwear supports you with softness and comfort throughout your period.
Developed in France with the expertise of ateliers working for leading lingerie houses, as well as French textile and patent experts, our technology is made up of a unique combination of three layers.
1. Organic Cotton Moisture-Wicking Layer
A few millimetres of ultra-soft, breathable moisture-wicking fabric made from organic cotton.
2. The Absorbent TENCEL™ Layer
An ultra-thin, eco-friendly TENCEL™ layer that absorbs flow quickly and continuously.
3. A Waterproof PUL Layer
A waterproof, breathable membrane that locks in flow for leakproof protection for up to 12 hours straight.
Period products represent a significant expense over a woman’s lifetime. On average, we spend between €5 and €10 per month on menstrual protection — that’s at least €300 to €600 over five years alone (not including all the underwear or pyjamas we’ve had to replace).
Réjeanne period underwear means no more buying disposable products every month, and no more throwing away dozens of tampons or pads with every cycle.
And one more major benefit: no risk of toxic shock syndrome — meaning less worry and more peaceful nights.
They can absorb the equivalent of 1 to 2 tampons.
Perfect for lighter periods, especially at the beginning or end of your cycle, or as backup protection alongside your usual menstrual products.
They absorb the equivalent of 3 to 7 tampons.
Designed for heavier flow days — usually the second or third day of your cycle — as well as overnight wear for extra peace of mind.
Rinse in cold water after each use and before wearing for the first time.
Run the water until it runs clear.
Wash cold on a delicate cycle.
Using a laundry bag is even better!
