What it does
FAQs / Q&A
How does this period underwear actually stop leaks?
It layers four to five protective layers together: an absorbent core, a moisture-wicking lining, and a breathable, waterproof TPU layer on the outside. That combination is what the brand calls LeakBlock, built to absorb menstrual flow while keeping the outer layer dry.
How many hours of protection do these period panties give?
This pair is rated for the Moderate flow level, good for up to 12 hours depending on how heavy your flow runs that day. If you're consistently heavier, the brand also makes a Heavy absorbency version worth checking out.
What's the right way to wash period underwear to protect the leak barrier?
Rinse in cold water first, then machine wash on a cold, gentle cycle. Skip fabric softener and bleach, since both can break down the waterproof lining over time, and let them air dry instead of tossing them in the dryer.
Can I wear these for exercise, sleep, or travel days?
Yes. The fabric is designed to be ultra-thin and breathable without added bulk, so it's made for work, exercise, sleep, and travel days alike, not just as a backup layer.
Do I still need a pad or tampon with these?
No, that's the point. These are built to be worn on their own for full leak protection, though plenty of people layer them as backup on heavier days or overnight.
