Say hello to our new leak-free Bikini — a swim staple with discreet added leak-proof protection. Made with the same reliable built-in tech used across our period underwear range, so you can feel confident that you’ll stay leak-free. Our new water-resistant outer material allows water to simply roll off, keeping you fresh and dry all day long, whether you’re going for a dip or simply laying poolside.

Full coverage across the bum and stomach keeps you feeling covered whilst our built-in tech makes sure you're protected all day long. Great for a moderate flow — absorbs the same amount as approximately three tampons worth.

Our new Swim range uses recycled nylon, made from waste like water bottles and fishing nets. 5% of all profits from our Swim collection will go to The Ocean Cleanup, who work to clear plastic from our rivers and oceans.

Finally!

Finally I found swimming panties that you can wear safely in water while with your period. I’m so happy about them that I want to buy another pair. Fantastic - it really works!!

Great

I bought the bikini bottoms to support my daughter who was worried she might start her periods on our first summer holiday in 3 years! She didn't and didn't need hers! I did need mine and normally I would just not go in the pool and not bother about it! I have a track record of coming on on holiday! But as it was nearly 40 degrees, even though I was nervous to try them, I was struggling in the heat, so thought I'd give them a go! I was only on a medium to light flow and I did panic a little but after the first time I realised I could trust them and it was a great freedom so thank-you. I wore them under my bikini but they were perfect to wear as they were, they just look like black bikini bottoms.

Wow - life changer

These are soooo good. I took a trip to the sea the other day and they held up perfectly, I was a little nervous at first but I had literally no problems!
