Absorbency guide

See how much flow our Hello Undies can absorb compared to regular (5ml) tampons.

So easy to care for

Three simple steps — that's all it takes

Wear

Put on like regular undies. Good for up to 8 hours depending on your flow.

Rinse

Rinse under cold water until clear. Takes just 30 seconds.

Wash

Machine wash in <30° using a mild detergent, then hang to dry. Ready to go again!

Before first use: Wash your Hello Undies before first use to activate the absorbent technology. Do not use fabric softener.
