Customer questions

Nope! Your period pants are there to replace any need for another product. That means you can just pull up your pants and go! No need to change or wash every time you go to the loo.

All styles of our pants are really easy to take care of. Follow these simple instructions and you can’t go wrong

  • Before washing, give them a rinse with cold water until the water runs clear. Do not soak.
  • Give them their very own bubble bath in the sink….or pop them in the washing machine at no hotter than 40 degrees. Do not use fabric softener.
  • Once squeaky clean, stretch them back to their original shape.
  • Air dry or rest on radiator and wear again – easy! Make sure to not tumble-dry.

    Really comfortable, lovely fabric and very leak proof. I will definitely be purchasing the black ones as well. I no longer even think of buying disposable period products as Hey Girls have such a good offer of quality, reusable products. Totally won over by Period Pants!
