FAQ

• Can I wear these on heavy flow days? Yes! The front-to-back extended gusset is specifically designed for heavy flow coverage. For your heaviest days, many customers pair them with a menstrual cup or disc for extra confidence — but on moderate days, they work beautifully on their own.

• How do I wash them? Simply rinse in cold water after use, then toss them in the washing machine on a cold cycle. Hang dry or tumble dry on low. No special care needed — they're as easy to maintain as your regular underwear.
