Our worry-free, period-proof swimwear lets you dive in with confidence. From beach trips to pool parties, splash without fear of leakage on lighter flow days.
Scarlet Period Swim Bikini Brief is the new way to relax at the beach or by the pool without having to worry about tampon strings, leakages or changing every few hours.
Offering 3 teaspoons of protection (which is roughly equal to up to 2 regular tampons or 1 regular pad), they're perfect for light flows or at the beginning/end of your cycle so you can swim with and without additional protection.
Made from luxe ribbed recycled polyester, featuring a flattering high waist silhouette with a leak-proof gusset, you can turn ‘no’ days into ‘go’ days at the beach. As Vogue put it, “You can now swim in peace this summer."
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).
We are committed to making mindful and sustainable choices which are good for your body and have big payoffs for the environment, which is why we’ve sourced recycled polyester for our swimwear.
Scarlet is a proud member of 1% for the Planet, joining a global community of brands and individuals giving back to the environment.
Scarlet Period Swimwear is designed to fit like normal swimwear, 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 tampons which means it can safely hold more liquid, and last for years not hours.
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 swim briefs 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.
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 our Toiletry Bag, so you can always pop them away and rinse when you're home if you need to.
