Your questions, answered

HOW DO THEY WORK?

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.

WHAT DOES THE ABSORBENCY LEVELS MEAN?

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 dates 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 around 4 regular tampons or 3 pads. It’s our heavy hitter, making them great for full-flow days and overnight. 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.

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.

DO I HAVE TO WASH THEM ASAP AFTER USE?

Nope – who’s that organised? That’s why our Laundry Bag is ace – simply throw your used pair into the bag and store it until 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! 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 wear, pop them in the washing machine with your next cold cycle - washing them before wearing activates their absorbency even more.

Great G-String but not the perfect fit for me

The absorbency itself is wonderful and the G-String is so well made with high quality material and elastic, but the cut feels quite low-rise to me, and I can't size up to test that out because they only go to a 16 unfortunately. It's still a great pair of underwear, but it's not the best fit for me personally.

Perfect for Workouts

Great underwear

Thought it’d feel too minimal, but it handled a light flow day like a boss. Heavy days I add a tampon. Done!

When in doubt, wear the G!

You know those days when your boobs hurt, your skin’s breaking out, and you know it’s coming? I wear this then. Just in case.
