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. It is loved by all; you can read some reviews.

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!). Use the 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 them in the washing machine with your next cold cycle - washing them before wearing activates their absorbency even more.

WHAT IS YOUR 30-DAY RISK-FREE TRIAL?

This is a new way to period, and we understand it may take a couple of goes to get into the swing of things. So, we 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.

HOW DO I PICK THE RIGHT SIZE FOR ME?

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 or letter sizing so no confusion (ie. Our large is a 12).

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