How do I wash period underwear?
Caring for your period underwear is simple. Rinse them in cold water after use, then toss them into the washing machine with your regular laundry (no fabric softener, please). Air dry, and they’ll be ready for the next wear. They’re designed to withstand multiple washes, making them a durable and eco-friendly option.

PFAS (Per- and polyfluoroalkyl substances) are chemicals sometimes used to make fabrics water-resistant or stain-resistant.

Instead, we focus on safe, non-toxic materials and rigorous testing to ensure quality and safety.
