Period knickers

My daughter started her periods at 10 years old. She is autistic. And was no way near ready for it. But this underwear has been great and made her more confident.

Great first use!

They were so good to have to hand when my first period started

So amazing!

My daughter is autistic and these have taken so much stress away. No more discomfort, no more leaks and embarrassment, less washing for me!

A must try

Transitioning to a life with periods comes with many adjustments but these pants have meant the transition is so much smoother.

Bought these for my 14 year old daughter and she absolutely loved them. Don't think she'll ever use disposable sanitary products again.

Got questions?

Q) Can I wear Fluxies all day without other period products?

A) Yes! Fluxies period pants have three built-in layers that absorb your flow, control odour, and prevent any leaks! Find out more about how period pants work.

Q) How many pairs will I need?

A) We always recommend starting with our Teen Period Kit, which includes all three styles of period undies in one kit. But, you can start with as many as you like!
