How Period Underwear Works & How To Clean It

Period underwear is slowly becoming the number one menstrual solution for girls & women around Australia. Among other menstrual products such as cups, tampons, liners and sanitary pads, period undies are ideal for those looking for a period-proof, leak free, rash-free and non-invasive monthly flow product. Whether it be for light or heavy periods during the day or overnight, they are the perfect solution!

Period-proof underwear is a must-have

Say hello to our NND x BONDS period proof underwear! 100% brushed cotton against the skin with a waterproof and absorbent period pad sewn-in to genuine BONDS® branded underwear.

Period underwear — all you need to know about them 

Here’s a quick guide for you to learn more about period undies — what they are, the benefits of using them and the ways you can take care of them.

What is period-proof underwear? 

While period underwear look like regular undies, they’re designed to keep moisture away from the skin as they absorb menstrual blood. Our period-proof underwear directly replaces disposable sanitary pad, liners and tampons and just like regular underwear, they can be washed and reused throughout your cycle.

How do period undies work?

Specifically designed to absorb menstrual blood, our period undies have a capacity of 100ml and 250ml. Our innovative pad is highly absorbent and provides a waterproof barrier to prevent leaks and accidents, so you can wear these undies for both lighter and heavy menstrual days. 

Why should you choose period undies?

Wearing period underwear is as comfortable as wearing a pair of your go-to everyday undies. Unlike other menstrual products, they do not cause irritation, rashes or bumps. They’re also washable and reusable, making them highly convenient, eco-friendly and budget-friendly! 

    How to clean your period underwear?

    One of the most significant advantages of opting for period undies is that they are simple and easy to care for. Here’s an easy 4 step guide to cleaning your period-proof underwear:

    Step 1. Soak or rinse your period undies

    After removing a used pair of period undies, soak them in cold water or rinse them until the water runs clear. 

    Step 2. Wash your period undies carefully

    We highly recommend washing period undies by hand and using a mild detergent to ensure they maintain their durability. If you’re in a hurry, put the period undies in a wash bag for a machine wash and adjust the setting to a delicate or gentle cycle.

    Step 3. Air dry your period undies gently

    Do not put your period underwear in the dryer — this can cause them to shrink. Always lay the underwear flat or hang it up to maintain the fabric’s layers and absorbing properties.

    Step 4. Treat the period smell

    In case you feel there’s a lingering odour — don’t fret, this is common — soak your undies in a light mixture of vinegar and water before you commence your routine wash.
