WUKA launches heavy-flow period-proof swimwear for competitive swimmers

WUKA pushed period swimwear out of the gentle-laps lane and into race-day territory with Lunafly Competition, a heavy-flow suit built for club training, junior competitions and intensive sessions. The brand called it the UK’s first heavy-flow period-proof swimwear for competitive swimmers, and that claim lands because this is not the usual light-protection add-on dressed up as performance.

The Lunafly line is aimed straight at the places where period anxiety can actually knock a swimmer out of the water: club practice, junior meets and competition days. WUKA says the bikini’s leakproof gusset holds 20ml of heavy flow, about four tampons or three regular pads, with no tampon needed. The suit is made from chlorine-resistant recycled nylon with reinforced gusset seams and a stay-put fit, the kind of construction that matters when a swimmer is turning, sprinting and drilling starts instead of lounging poolside.

That is what separates Lunafly from WUKA’s earlier period swimwear. The brand’s existing swim line uses recycled ocean waste, built-in leak-proof technology and UV50+ protection, but it is pitched for light to medium flow days. This new competition range is the harder ask: heavier flow, tighter training schedules and more pressure to perform without constantly thinking about the water. WUKA says the Lunafly Competition bikini should last roughly two seasons of regular club training, and it is priced at £70.

The pitch also gets a useful reality check from Swim England, which says specific period swimwear can be worn in training and in competitions held under Swim England regulations. Its revised guidance was meant to cut down on confusion between its own rules and World Aquatics rules, and that distinction matters because period-friendly kit is not universally welcomed across every governing-body setting. In that context, WUKA is not just selling comfort. It is plugging a genuine access gap for swimmers who want to stay in the sport without treating their cycle like a blackout.

WUKA, founded by Ruby Raut in 2017, has been building this lane for a while. The brand has already moved into period-proof sportswear, including what it described as the UK’s first period-proof tennis skort. The swim launch fits the same playbook: menstrual protection that looks less like a compromise and more like kit built to keep up with the athlete wearing it.
