You have questions. We have answers.
How do they work?
Scarlet Period Underwear is designed to fit like normal underwear, and feature a multi-layered leak-proof technology that wicks away moisture, absorbs and contains fluid to keep you dry and protected.
The built in leak-proof technology is harder working than disposable pads which means it can safely hold more liquid, and last for years not hours. Loved by all, you can read some reviews.
What does the absorbency level mean?
Super Light: Holds up to 1 teaspoon, which is equal less than 1 regular tampons. Think of it as a new-age panty liner, so it’s great for spotting as well as light leaks and discharge. Try: Invisible Thong
Light: Holds up to 3 teaspoons, which is equal to 2 regular tampons or 1 pad. This is for light days to save you from pesky drips, discharge, and lighter flows. Try: G-String or Bikini Brief in Light
Moderate: Holds up to 5 teaspoons, which is equal to 3 regular tampons or 2 pads. Go for this on your moderate days, or as extra defence on heavy days with our Period Cup. Try: High-Waisted Brief or Bikini Brief in Moderate
Heavy: Holds up to 7 teaspoons, which is equal to 4 regular tampons or 3 pads. It’s the heavy hitter, making them great to wear on their own, day or night. Try: Boyshort or Period Cup
Do I need to wear a cup, tampon, or liner too?
Depending on the absorbency level you choose and the heaviness of your flow, you can wear our period panties on their own or as backup protection along with a Period Cup or tampon. Take the time to explore a routine that works for you.
How do I wash them?
After use, rinse them in cold water (we recommend in the shower) until they run clear. Then, machine wash in cold water with mild detergent (no bleach!). Try our Laundry Bag to safeguard them on laundry day. Then just hang out to dry (the sunnier the better) or tumble dry on low - that’s it!
TIP: If it’s your first wear, pop them in the washing machine with your next cold cycle - washing them before wearing activates their absorbency even more.
How do I store them post-swim?
We recommend travelling with a water-resistant travel bag such as our Toiletry Bag. Give them a good rinse to remove any chlorine or salt water, before stashing away. Once home, either machine wash in cold water with mild detergent or if wearing them again soon, hang them out to fully dry (the sunnier the better).
