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 a disposable pad, which means it can safely hold more liquid and last for years, not hours. Loved by all, you can read some reviews.

When it comes to our periods, every flow is different - heck, every day is different. That's why we have a range of absorbency levels to suit. Use this as a guide to get the right fit for your flow so you'll never stress about leaking on the train again.

Super Light: Holds up to 1 teaspoon, just slightly less than 1 regular tampon. 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, Bikini Brief in Light or Swim range

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 an 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 around 4 regular tampons or 3 pads. Our heavy hitter makes them great for full-flow days and overnight. Try: Boyshort or Period Cup

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. Take the time to explore a routine that works for you.

On heavy days, we recommend travelling with a water-resistant travel bag such as the Toiletry Bag and a spare pair so you can change them if needed, pop them straight away and rinse (if you CBF) when you get home.

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

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

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.

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 soaps and traditional femme washes. That means it's free of parabens, silicones, fragrances and sulfates - which are the main trigger 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.

Confused if you should be cleansing down south? We have all the answers on our blog.

We get it - sizing for bottoms is anything but standardised. Which is why this size guide will help break it down for you. For extra ass-urance, make sure to whip out your trusty measuring tape. (Most likely stashed at the bottom of your junk drawer.) 

Please make sure to check both our numeric and letter sizes so there is no confusion (e.g., our large is a 12). When in doubt, we advise you to size up.
