Product Description
Like your favourite swimwear, but better
- This flattering bikini bottom features a high-waisted fit that hugs your body and absorbs up to 4 tampons. Our mind-blowing concealed lining absorbs light period or discharge both in and out of the water.
Comfortable fit
- Our bikini bottom features an uber-flattering high-waisted design, thick supportive waistband and full bum coverage. It completely replaces the need for disposable pads, tampons and liners at the beach or pool.
Premium quality
- Made of Pre-consumer recycled Nylon means less waste heading to landfill – and less energy use. Our chlorine-resistant swimwear can be used again and again for years to come.
Go from brunch to the beach in protected style
- thanks to our super slim and discreet patented swimwear technology. A Sporty mesh inner is fast drying, absorbs liquid, and locks it away. Even better it helps to control odour and is backed with a breathable, waterproof layer.
Hot tip!
- Make sure this period swimsuit fits tight against the leg so our leakproof tech absorbs your period, and not the ocean or pool!
Care recommendations
- We recommend washing on a gentle cycle, cold machine wash, and hanging to dry for a sun-kissed feel. No fabric softeners and strong detergents. No tumble-drying or exposure to high temperatures. Do not soak. Once dry, store your Modibodi garments in a dry laundry bag.

I just have to say—OMG! Period swimmers, where have you been all my life? Whoever invented these is a genius. I’ve spent my entire adult life avoiding swimming during my period, but today I finally had the courage to try them. With a medium flow, I spent 4 hours in the water—no leaks, no worries, just total freedom. It was honestly the most liberating experience. I can’t thank you enough. This is by far the best purchase I’ve ever made. For me, it means more time with my kids, enjoying beautiful beaches and extra pool time without a second thought. I’m beyond happy! True to size, don’t order a size bigger.

These are my first period proof swimmers and they did the trick on holidays. I only wore for a few hours so they seemed very reliable for short uses.

I didnt really think these would work that well but they are fantastic. They arent suitable for swimming on heavy days, but have allowed me to enjoy the warm weather and go swimming even when I have my period. They are also really comfortable. I didnt have good fitting bikini bottoms so am wearing these even when I dont have my period as they are so comfy and give tummy support.Highly recommended!

It didn’t work for me. Water went in and probably leaked out( not sure because I used it in river😄). Maybe if I had sized down it would be tighter and worked better
Maree –

AMAZING!
These period tankini bottoms saved my holiday!!! I was so nervous about going on holiday during my period, I’m someone that HATES tampons and my menstrual cycle has been all over the place since changing contraception. I have worn these multiple times whilst being fairly heavy and they have not failed once! Best invention ever! I am a size 14 and ordered XL and they fit perfect. Sometimes a little baggy round the bum area, but still comfortable and I was not worried once I got used to it!
