Introducing the Scarlet Period High-Waisted Brief 3-Pack (plus, a Laundry Bag). These comfy period undies in a high-waisted style deliver full coverage period protection during your moderate flow days.
With super soft, superior modal cotton, multi-layered leak-proof technology, and a fast-acting built-in absorbent gusset, it can absorb 5 teaspoons of fluid (which is roughly equal to 3 regular tampons or 2 regular pads), making them great for back up protection during your heavier days, or on its own on moderate ones.
Best part? You also save $10 and get free shipping to boot!
Machine washable and reusable, they’re an eco-friendly and cost-effective alternative to disposable pads and tampons.
After use, rinse in cold water until it runs clear. Machine wash cold with mild detergent, do not use bleach or fabric softener. Line dry or tumble dry on low.
45% Modal, 45% Cotton, 10% Spandex, and a Polyester Quick Dry Gusset. Free from added chemical treatments, including PFAS (independently lab tested).

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 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.
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.
If you are curious about Cups, you can click here to learn more about how Period Cups work. They’re really not as scary as you think!
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 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.

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. 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.
