What are period pants?

Period pants look and feel like normal underwear, except you can bleed in them. Trust your pants to deal with whatever flows your vagina throws at them, without any unexpected surprises.

How long can I wear the pants for?

Over an average use of 12 hours, consumer tests (in France, UK & Colombia) showed that 90% of women did not have any unexpected accidents. Depending on your period flow, this can be up to 12 hours.

Are period pants suitable for heavy periods?

Our current range of intimawear by Bodyform™ offers protection for light, medium and heavy period flow.

What are the benefits of these pants?

intimawear by Bodyform™ are a range of pants designed for any flows your vagina throws at them. There's no need for any other period products as the built-in absorbent gusset is there to lock everything snugly in. They're also better for the planet and a more sustainable option for your period - just bleed, wash and repeat, wear after wear.

Will the pants smell after use?

Don't worry! The pants have a specialised wicking and absorbent layer that is treated with an antimicrobial odour control system - which sounds technical but basically means it intercepts any smells, even if it's hot and sweaty.
