If you've ever used period undies, you'll know too well how they've revolutionised the way women experience their monthly cycle, offering comfort, leak-proof protection, and sustainability all in one.

If you’re just discovering them or simply curious about how period undies work, this guide will walk you through everything there is to know.

So, How Do Period Undies Work?

Period undies look and feel like regular underwear but are designed with built-in absorbent layers that soak up period blood. They typically use modern moisture-wicking, leak-resistant, and odour-controlling technology that keeps your vaginal area dry and comfortable throughout the day.

Depending on the style and brand, period undies can hold the equivalent of 1 to 5 tampons' worth of fluid. Some women use them alone, while others wear them as backup with tampons or a menstrual cup, especially on those heavier days.

How to Wash Period Undies

Taking care of your period undies properly will help them last longer and stay absorbent:

  1. Rinse in Cold Water: After use, rinse your period undies under cold water until the water runs clear.
  2. Machine Wash: Wash on a gentle, cold cycle with mild detergent. Avoid using fabric softener or bleach, as these can affect absorbency.
  3. Air Dry: Hang them to dry naturally. Avoid putting them in the dryer, especially when they're made from bamboo fabric.

With the right care, your period undies can last for up to 2–3 years, making them a cost-effective and sustainable alternative to the off-the-shelf disposable products.

Switching to period undies can save you up to AUD 470 per year over three years compared to disposable products! That's a lot of money to spend on other things you love. 💖

Period Undies for Teens

Period undies for teens are a great option for young people who are just starting their period journey. They're more sustainable than pads, gentler than tampons, and offer discreet protection that feels just like normal underwear.

We've heard that teens love them for school days, sleepovers, and sports, as they provide peace of mind without the worry of leaks. No more days at school worrying about disposing of pads or tampons. Period undies help young people feel more comfortable during their cycle.

Period Undies for Heavy Flow

For those with a heavier cycle, period undies for heavy flow offer high absorbency and full-coverage designs. These are made to handle heavier days, holding more fluid than tampons and offering extra leak protection.

Many women in our community like to pair heavy-flow period undies with a menstrual cup on heavy days, especially overnight or during long days out.

Bamboo Period Undies

We love bamboo period undies because of their softness, breathability, and eco-friendly properties. Bamboo fabric is naturally antibacterial and hypoallergenic, making it better for the sensitive skin of the vagina, while providing airflow and helping to reduce odour. It’s also a more sustainable choice because bamboo grows quickly with minimal water and no pesticides, making it one of the most environmentally responsible options.

From teens to heavy flow and everything in between, period undies offer a practical, planet-friendly solution for your cycle. And if you’re after softness and sustainability, bamboo period undies are Pinc's choice for comfort and conscious living.
