Super absorbent period underwear

Leakproof Period Pants

Wear them all day. Hold as much as 8 tampons.

Be comfortable. Be confident.

For periods and bladder leaks

We use the most advanced fabric technology to bring you incredibly absorbent knickers that are under 2mm thin.

Stay dry

Unique push-pull one-way wicking layer to force wetness into the absorbent layers below and keep it there.

Super absorbent

Resistant to compression leakage when you sit down. Fluids are dispersed throughout the core by capillary action, eliminating the need for multiple layers (and bulkier knickers); even for heavier flows.


Breathable yet leakproof layer bonded directly to the absorbent core so fluids cannot escape.

UK supply chain

Made in the UK

Designed and made in the UK. Our cotton jersey is knitted in Nottingham. Our elastic is from Leicester. Our period pants are made in West Sussex.

Be the change

Save money. Save the planet

Over 4m disposable tampons and pads are flushed down UK toilets every day and about the same go to landfill. Being up to 90% plastic they do untold damage to the environment.

And the final insult? They end up costing more money than reusables.

Featured reviews

I can’t believe how dry these period pants keep me. Even on my heavier days I can wear them all day. I always take a spare pair to work of course but never need them.

I really notice how much quicker these period knickers are to dry compared to the brand I used to wear. And they are so thin. My old ones used to feel a bit bulky but not these.
