Period Knickers FAQs

What are period knickers and how do they work?

Period knickers are designed to look like regular underwear but feature multi-layered absorbent gussets that soak up menstrual fluid to prevent leaks. Their moisture-wicking fabric draws fluid away from your skin, while anti-odour properties keep you feeling fresh. Depending on your flow, you can often wear period knickers for a whole day before rinsing in cool water and washing in your machine. In our collection, you’ll find period knickers in high-leg, brief and shorts styles.

How long can you wear period knickers before you need to change them?

You should change your period knickers at least every eight to twelve hours, or sooner if they begin to feel damp. On heavier flow days, switching to a fresh pair after four to six hours helps you stay confident and leak-free. In our collection, you’ll find period knickers crafted in a choice of light, medium and high absorbency levels, making it easy to tailor your protection throughout your cycle.

Conquer your monthlys in style with our quality period knickers. We’ve got a wide variety of fits, cuts and colours to match your requirements, as well as varying absorbencies to deal with every day of your flow. Our leak-proof designs are made to inspire confidence and ensure all-day comfort.

We’ve got classic beige period knickers and period knickers in black, alongside options in pink and green shades. Browse comfortable bikini styles and full briefs with a high waistline, as well as high-leg knickers and full-coverage knicker shorts for maximum convenience. Just because it’s your period doesn’t mean you can’t enjoy a little style, either – you’ll find fun prints, patterns and options with lace detailing in our collection.

Choose from super-heavy, heavy, medium and low-absorbency knickers, tailored to your flow level and how often you want to change. You’ll enjoy helpful features like our three-layer gusset that draws moisture away from the body, with an anti-odour middle layer for total peace of mind. Our StayNew™ technology ensures that the colour, print and finish remains fresh for longer, wash after wash.

Pick up a handy multi-pack of three or five pairs to cover you for your whole period, or try out individual designs first to make sure the shape and style works for you. Our period knicker accessories – including subtle travel bags with waterproof and odour-proof linings – help you keep going and living life to the full without a hitch, no matter when you’re due.
