Scarlet Period Underwear is designed to fit like normal underwear and features multi-layered leak-proof technology that wicks away moisture, absorbs fluid, and contains it 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.

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.

Super Light: Holds up to 1 teaspoon, which is equal to less than one regular tampon. Think of it as a new-age panty liner, so it’s great for spotting, light leaks and discharge. Try: Invisible Thong

Light: Holds up to 3 teaspoons, which is equal to 2 regular tampons or one 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

Moderate: Holds up to 5 teaspoons, which is equal to 3 regular tampons or 2 pads. Go for this on moderate days or as extra defence on heavy days with our Period Cup. Try: High-Waisted Brief or Bikini Brief in Moderate-Heavy

Heavy: Holds up to 7 teaspoons, which is equal to 4 regular tampons or 3 pads. Our heavy hitters are great to wear on their own, day or night. Try: Boyshort or Period Cup

We get it, sizing for bottoms is anything but standardised. Which is why this size guide will help break it down for you. Make sure to check both our numeric and letter sizing so no confusion (ie. our large is a 12).

When in doubt, feedback tells us better to size up. Still confused? You can also email us for help at support@scarletperiod.com.

Sure is! We formulate all our products using a blend of science and nature, never animal by-products. Our products are only ever tested by our community, right here in Australia.

Our All-Over Daily Cleanser formula is a pH-balanced alternative to harsh femme washes. That means it's free of parabens, silicones, and sulphates (which are some of the triggers for disrupting your vaginal flora and pH levels). Just remember it is for external use only. And in the (very) unlikely event of irritation, discontinue use.

Nope, who’s that organised? That’s why our Laundry Bag is ace! Throw your used pair into the bag and store it when you have a full load. Some people like to give them a quick rinse in the shower before popping them into the bag, and others don’t. It won’t affect the lifespan of your underwear.

Once ready, toss them in on a cold wash cycle with mild detergent (no bleach!). DW, your other clothes will be just fine! You have two options for drying: tumble dry on low or hang them out to dry in the sun. 

TIP: If it’s your first time wearing them, pop them in the washing machine with your next cold cycle. Also washing them before wearing activates their absorbency even more.
