What it does

Heavy flow days ask a lot of underwear, and the spec sheet here answers with four protective layers, a breathable waterproof TPU barrier included, wrapped in a nylon-elastane brief that reads soft, not clinical. It suits anyone ready to retire the disposable-pad shuffle, with reviewers of reusable period wear pointing to the twelve-hour window as the real draw. Skip it if a light-day liner is what you're after, this one is built for the heavy end of the cycle. A cold rinse before the first wash helps the LeakBlock layers perform from day one.

FAQs / Q&A

  • How long do these period panties last before I need to change them?

    It depends on your flow, but the LeakBlock layers are built for up to 12 hours of protection on heavy days. Pay attention to your own pattern the first cycle or two and adjust from there.

  • Do I still need a pad or tampon with these on heavy days?

    These are designed to work on their own, the four-layer LeakBlock construction is the protection, not a backup. If your flow runs unusually heavy, pairing with a cup for extra peace of mind is a personal call, not a requirement.

  • How do I wash and care for UVA period underwear?

    Rinse them in cool water soon after wearing, then machine wash on a gentle cycle and air dry. Skip fabric softener and high heat, both can wear down the waterproof TPU layer that does the real work.

  • What size should I order for the best fit?

    This listing is the size L option. Period underwear generally fits close to your everyday size, so matching your usual underwear size is the safest bet for full leak protection.

  • Can I wear these for exercise, sleep, or travel?

    Yes, the breathable, ultra-thin fabric is built for exactly that: work, workouts, sleep, and travel days all included. The same pair that gets you through a desk day works just as well on a flight or a run.

Care Instructions

  • Rinse in cool water promptly after wearing, before tossing in the hamper.
  • Wash on a gentle cycle to protect the leakproof layers.
  • Skip fabric softener, it can coat and weaken LeakBlock performance.
  • Air dry fully before wearing again or storing.
  • Avoid bleach and high heat, which stress the TPU barrier.
