The Scarlet Period Boyshort is a bestseller for a reason. This easy-fitting period underwear, designed in a boyshort style, provides full coverage and protection during your heavier flow days. Wear them like regular underwear, without worrying about leaks, stains, or odours.
In addition to three pairs, this pack also comes with an on-the-go Toiletry Bag to take all your period essentials with you wherever you go.
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. Read more about looking after your periodwear here.
Pop your Boyshort in your Toiletry Bag to keep them clean and ready to go whenever you need.
Made with naturally soft, comfortable, and breathable GOTS Certified Organic Cotton, and featuring a quick-drying built-in absorbent gusset, it can absorb up to 7 teaspoons of fluid (equivalent to roughly 4 regular tampons or 3 regular pads). This makes them ideal for heavy days or overnight wear.
Made from: 95% Organic Cotton, 5% Elastane and a Polyester/Elastane/PUL Quick Dry Gusset. Free from added chemical treatments, including PFAS (independently lab tested).
Harder working than disposable pads and tampons, they last for year not hours.
Did you know more than 12 *billion* pads and 7 *billion* tampons are thrown out every year. The average person with a period uses 11,000 pads, tampons and panty liners in their lifetime. By switching to Scarlet, you're supporting a period and planet positive future.
Scarlet Period Underwear is designed to fit like normal underwear, and feature a multi-layered leak-proof technology that wicks away moisture, absorbs and contains fluid 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 here.
Super Light: Holds up to 1 teaspoon, which is equal less than 1 regular tampons or 1 liner. It’s the perfect everyday underwear for light leaks and discharge, even when you’re not on your period.
Light: Holds up to 3 teaspoons, which is equal to 2 regular tampons or 1 pad, making them perfect for saving you from pesky drips, discharge, and lighter flows.
Moderate: Holds up to 5 teaspoons, which is equal to 3 regular tampons or 2 pads. Wear on moderate dates, or as extra defence on heavy days with our Period Cup.
Heavy: Holds up to 7 teaspoons, which is equal to 4 regular tampons or 3 pads, making them great to wear on their own, day or night.
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.
And if you are feeling Cup curious, you can learn more about them here. They’re not as scary as you think!
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 them in the washing machine with your next cold cycle - washing them before wearing activates their absorbency even more. You can read more here.
This is a new way to period, and we understand fit may take a couple of goes to get into the swing of things. So, we have a 30-day risk-free trial to support you to 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 recommend travelling with a water-resistant travel bag such as the Toiletry Bag, along with a spare pair, so you can always pop them away and rinse when you're home if you need to.
