DETAILS

Innovative period-approved swimwear with a flattering high waist and stay-in-place booty so you can catch waves in style with confidence. 

Dive in knowing you have 2 teaspoons of protection (which is roughly equal to up to 1 regular tampons), making them leakproof for light flow days and spotting, and great as a backup on heavier days. 

Designed with built-in leak-proof protection, these boy short swimwear bottoms use luxe ribbed recycled polyester to stop your flow from going out and water getting in.

Your questions, answered

HOW DO THEY WORK?

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.

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? Click for more information on our Returns Policy and our 30-Day Trial Policy. You can also email us at support@scarletperiod.com.

DO I NEED TO WEAR A CUP  OR TAMPON TOO?

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.

HOW DO I WASH THEM?

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.

WHAT IS YOUR 30-DAY RISK-FREE TRIAL? 

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.

HOW DO I STORE THEM POST-SWIM?

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.
