"I've tested these period pants on long haul flights, overnight, in the office and on my work from home days, and honestly? I couldn't rate them more highly."

I’m a huge convert. Yes, these period pants are leakproof, but also comfy, and dare I say – a bit sexy.

They're SO damn comfy. A dream to wear and leaving you leak-free for 10 hours, they're stretchy, lightweight and quick-drying.

Soft and secure.

I bought these to try out after seeing an ad and now I’m obsessed. Feels like regular underwear but does so much more. Really comfortable and stay in place

A game-changer. I used to wake up worried about stains but not anymore. So soft and do the job perfectly. Love them!
