DETAILS

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 2 teaspoons of protection (which is roughly equal to up to 1 regular tampons), 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."

Your questions, answered

HOW DO THEY WORK?

Scarlet Period Swimwear features a multi-layered leak-proof technology that absorbs and contains fluid. An added waterproof inner layer then works to stop any menstrual fluid from leaking out, and water from getting in.

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

Still confused? You can also email us at support@scarletperiod.com.

DO I NEED TO WEAR A CUP  OR TAMPON TOO?

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.

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

HOW DO I WASH THEM?

After use, give them a good rinse in cold water to remove any chlorine or salt water. Now, just chuck them in one of our handy Laundry Bags to safeguard them until laundry day.  

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, we recommend air or line drying after washing – it's the VIP treatment for those absorbency layers. And if you must tumble dry, only bring LOW heat (double check, cause who has ever decoded dryer hieroglyphics?!).

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 DOES THE ABSORBENCY LEVELS MEAN? 

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 different needs. 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 equal less than 1 regular tampons. 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 or Bikini Brief in Light 

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 equal to 4 regular tampons or 3 pads. It’s the heavy hitter, making them great to wear on their own, day or night. Try: Boyshort or Period Cup

HOW DO I STORE THEM POST-SWIM?

We recommend travelling with a water-resistant travel bag such as our Toiletry Bag. Give them a good rinse to remove any chlorine or salt water, before stashing away. Once home, either machine wash in cold water with mild detergent or if wearing them again soon, hang them out to fully dry (the sunnier the better).
