Period underwear should do more than catch leaks. It should feel like the pair you would choose even when you are not on your period.
Rudie bamboo period underwear has a main body made from 92% viscose derived from bamboo and 8% elastane. Technical layers are used where they are actually needed in the leak-resistant gusset, rather than throughout the entire pair.
The buttery-soft, bamboo-rich body is designed to feel breathable and comfortable, while the absorbent gusset manages period flow where it matters.
Rudie period underwear uses a thin multi-layer gusset to provide absorbency from light to heavy flow without feeling like a bulky pad.
OEKO-TEX Standard 100 certified materials have been tested for harmful substances, giving you extra reassurance about what sits against your skin.
Cold wash, air dry and wear them again. By replacing some single-use pads and tampons, reusable bamboo period underwear can help reduce the amount of period waste you throw away over time.
