Why BP3?

Secure | BP3 Underwear


BP3 undies are super comfortable and secure. They give you the confidence to live your life without worrying about leaks. They can hold 2-3 tampons worth of blood.

Stylish | BP3 Underwear


Pads are bulky and unsightly. BP3 knickers are discreet but absorbent. They have no VPL, so they can be worn under tight gym leggings or going out clothes.

Sustainable | BP3 Underwear


You're ditching traditional sanitary products (tampons and pads) that cause 200,000+ tonnes of waste each year. Our underwear is washable – so good for the planet AND your purse.
