"I've always been paranoid about swimming on my period .... After trying the High-Waisted Swim Bikini Briefs, my confidence has completely changed!"
We'll keep this brief. High-Waisted Swim Bikini Briefs for swimming. Period Bikini Briefs for living. Leak-proof protection, always.
Breaststroke? Freestyle? Doggy paddle? There are different strokes for different folks, but the Scarlet Period Your Brief + Swim BFFs has everything you need to lap with confidence.
Included in this set (which saves you $8!) is our Period Swim Bikini Brief. Not only does it give you 2 teaspoons of protection (which is roughly equal to up to 1 regular tampons), it also matches seamlessly with the tops already in your bikini drawer.
Post-swim, simply pop them in our waterproof Toiletry Bag and swap into the Bikini Brief for hours of leak-proof protection. Made with breathable and buttery soft organic cotton, it's period underwear that feels like you're wearing, well, regular underwear.

Machine washable and reusable, our Period Underwear is 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.
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 is a proud member of 1% for the Planet, joining a global community of brands and individuals giving back to the environment.
Scarlet Period Swim and Underwear both feature a multi-layered built in leak-proof technology that absorbs and contains fluid. Our swimwear also has an added waterproof inner layer works to stop any menstrual fluid from leaking out, and water from getting in.

When it comes to our periods, every flow is different. Heck, every day is different. Which is 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, which is just a bit 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
Depending on the heaviness of your flow, you can wear on their own or as backup protection with a Period Cup on moderate to heavy days.
If planning on swimming, we recommend travelling with a water-resistant travel bag such as our Toiletry Bag, along with your clean pair, so you can easily and cleanly do a switcheroo.

For underwear, some people like to give them a quick rinse in the shower before throwing into a Laundry Bag for wash day, and others don’t. It won’t affect the lifespan of your underwear. When it comes to swimwear, it’s always best to give them a good rinse to remove any chlorine or salt water, before stashing in a water-resistant travel bag such as our Toiletry Bag until you get home.
Then, 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.

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.)
Make sure to check both our numeric or letter sizing so no confusion (ie. Our large is a 12). And when in doubt, we advise to size up.
