Period swimwear is a category that has genuinely changed swimming for a lot of people. Built-in leak protection — woven directly into the gusset of the swimsuit — means you can swim confidently during your period without relying on tampons, menstrual cups or other products that may be uncomfortable in the water.

At Splash Swimwear Darwin, our period swimwear range includes one pieces, bikini bottoms and swim shorts designed specifically with absorbent inner layers. The protection is built into the garment itself, not added as an insert, so there is nothing additional to manage before or after swimming.

Period swimwear works on the same principle as period underwear — a multi-layer gusset that captures flow before it can escape into the water. The absorbency levels vary by brand and style, with most designed for light to moderate flow. They are most effective when used alongside other protection for heavier days, or as standalone protection for lighter days or spotting.

Love Luna is our dedicated period swimwear brand, offering a range of one pieces and bikini bottoms designed for everyday wearability as well as functional protection. Their swimwear is available in a range of sizes and styles that work for different body shapes.

Period swimwear is washable and reusable, making it a practical and sustainable option for regular swimmers.

While you're here, have a look at our girls' swimwear in sizes 8–16 and chlorine resistant swimwear. Labels to look for here include Love Luna Period Swim and Funkita. It all sits within our wider women's swimwear.
