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.

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

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! 

If it’s your first wear, pop it in the washing machine with your next cold cycle - washing it before wearing activates its absorbency even more. Click to read more about how Period Underwear works. 

It is a reusable period cup made of 100% soft medical-grade silicone. It is worn internally like a tampon but collects, rather than absorbs, your menstrual flow. 

As it has more than 2.5x the capacity of a regular tampon, you can safely wear it for up to 8 hours before emptying. The Scarlet Period Cup is designed for ultimate comfort. Once your cup is in place, you shouldn't feel a thing.

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.) 

Remember to check both our numeric and letter sizes so there is no confusion (e.g., our large is a 12). When in doubt, feedback tells us it is better to size up.

We also have a 30-day risk-free trial to help you find the perfect pair. Basically, if it’s your first time shopping with us and you’re not happy with your product, you may be eligible to claim a refund on that product, even if it’s used. Just email us at support@scarletperiod.com. 

We get asked this a lot. Simply take out your Scarlet Period Cup and empty it into the toilet. When out and about, we suggest keeping a bottle of water and a few sachets of our Cup Wipes handy so it’s super easy to wipe your cup clean. Our Cup & Hand Wash, is a pH-balanced, low-foaming wash designed specifically to clean your Scarlet Period Cup.

Make sure to check that the holes at the side of the cup are clear before reinserting the cup. No mess, no fuss.
