LOOKS: SIMPLE.

REALITY: ANYTHING BUT.

Standalone period swim bikini bottoms with up to 30 ml absorbency, soft silicone-grip leg seals and a sealed, impenetrable period-safe barrier.

Up to 30 ml absorbency, around six regular pads' worth.

Integrated silicone grips close leak-prone gaps at the legs

Mix and match with any bikini top.

SEALED IN INNOVATION

Standard period swimwear often relies on the whole brief fitting tightly. Our design targets one of the places leaks are most likely to happen: the leg openings.

Soft silicone grips are integrated inside each leg opening to form a close, flexible seal against her skin.

They close leak-prone gaps as she swims, dives, kicks and tumble turns, without relying on side ties or an outer layer to hold the protection in place.

This is fit-led leak control built into her PSBBs as an extra safeguard against awkward mishaps.

Low-key from the outside. Built for max confidence on the inside.

PERIOD STRESS IN THE POOL OR AT THE BEACH?

Hard pass.

PSBB packs 30 ml of menstrual flow into its seriously innovative integrated protection panel.

Let's put that in perspective >> 30ml is approx six pads' worth (based on a 5 ml regular-pad comparison) of protection.

AND, it all stays locked under a moisture wicking top layer so no, you WILL NOT feel like you're wearing a wet nappy. Promise.

LOOKS LIKE SWIMWEAR. WORKS LIKE PERIODWEAR.

Simple basic black and classic cut pairs with practically any bikini top... so you can wear the swimwear you like without advertising that your period came too. BONUS.

Quick-dry, chlorine-friendly fabric makes them ready for pool training, beach days, holidays and the best type: the last-minute, I-need-to-submerge-myself-stat quick dip.

ABSORBS PERIODS. NOT POOLS.

A sealed, impenetrable barrier locks menstrual flow in and blocks pool or sea water from flooding the absorbent layers.

Made for swimming, diving and tumble turns
She should not need to sit carefully at the edge of the pool because her period arrived. These bottoms are designed for pool and beach use: swim training, dives, kicking, tumble turns, beach swimming, holidays and school swimming. The silicone-grip leg seals move with the body and help the bikini stay close to the skin where leak control matters most.

 

How Are These Different from UnderSwim: Invisible Period Swimwear Undies?

Top line:
Period Swim Bikini Bottoms are the swimwear. UnderSwim goes underneath it.

Choose PSBBs when you want standalone period swimwear to pair with any bikini top. The thicker outer fabric creates a smooth, discreet silhouette and disguises the seams of the protection panel.

Choose UnderSwim when you want invisible period protection beneath a one-piece, racing suit or existing bikini bottom.
