People who menstruate, sweat, or have light bladder leakage or discharge are encouraged to make the switch to our reusable, environmentally friendly alternative to regular menstrual products or panty liners. Everyone deserves to feel fresh and comfortable!

How do Undercovers differ from other period underwear brands?

Undercovers underwear are designed with a super slim quick-drying gusset so they look and feel like normal underwear - no bulky padding.

The entire outer fabric of Undercovers underwear is leak-resistant which stop leaks from wicking around to the outside of the gusset and beyond.

Undercovers have been tried and tested for the last 8 years to ensure you’re getting the ultimate period product! Our underwear are the only brand manufactured right here in Australia, so you can shop with confidence knowing that you are supporting small, local businesses. Undercovers are Australian Made and owned. Based in Melbourne, we recognise and uplift other small businesses along our production line and supply chain, from our designer to our manufacturer, photographer and graphic designers. With every purchase we’re also supporting charities that empower women and assist those in need.

Undercovers let you live free from worry with total peace of mind by protecting you against life’s little leaks.

Can Undercovers replace sanitary pads and/or tampons?

Depending on your flow and the style choice – yes!

Each style is labelled with their level of absorbency so you can select the style that best suits you and your needs. Whether its overnight, heavy flow, or those ‘just in case’ days, undercovers has an option for you.

How do I care for my Undercovers?

We recommend rinsing your undercovers under cold running water until the water runs clear, then pop them into the wash in a wash bag on a delicates cycle, and then hang or lie flat to dry.

We have made Undercovers underwear with some seriously clever little fabrics that will look after you day after day as long as you look after them. Please read our care guide - click here -and remember to never use any kind of bleach, fabric softener, dryer sheets or harsh detergent. These products will shorten the life of your new Undercovers.
