“How do period undies actually work?”
It’s the question we hear most — and we get it. Comfy and leakproof? It sounds too good to be true. Though we like to think it’s magic, how it works is simply clever science that starts with our 3-layer leakproof technology.
Made from soft, thin and breathable fabrics, Undercovers are just like your everyday favourite undies, but designed to give you complete protection and total confidence. When you need it most, we’ve got you covered.
We’ve got layers, baby
Designed, prototyped and tested with the help of RMIT School of Fashion and Textiles consultants, Undercovers’ period undies use an advanced, multi-layer leakproof tech made up of three super thin, breathable layers. Backed by science and tested for reliability.
Top Layer
The first layer is designed to absorb and wick away moisture — keeping you comfy, dry and secure.
Middle Layer
The second layer is made with a soft, absorbent cotton paired with a breathable, waterproof barrier. Goodbye leaks, hello comfort.
Outer Layer
The outside layer of our period undies is leak-resistant all over — not just in the gusset. This keeps you feeling totally secure and fresh, while going the extra mile to prevent leaks.
No learning curve needed
Unlike traditional period care products, period undies are super easy to use with zero learning curve involved. Simply choose the undies that suit your flow and style, and you’re good to go. No fuss, no frills.
Light Flow
From cotton g-strings to luxe boyleg briefs, these are the perfect option for the lighter to medium flow days of your period. Our Light + Medium period undies hold 1-3 tampons’ worth. For everyday protection, we’ve got you covered.
Heavy Flow
Say goodbye to constantly changing your tampon or waking up to any overnight surprises. The stylish high-waist and bikini cut undies in our Heavy + Super range hold up to 4-5 tampons’ worth for maximum absorbency and comfort.
Tips to Keep You Covered
First time
Try them on a lighter flow day to build up confidence. Everyone’s flow is unique, so it’s helpful to understand which absorbency works best for you before hitting the town.
Travelling
Pack a couple of extra pairs to keep you covered on the go. Our wet bag is a mess-free way to store used pairs until you can wash them.
Overnight
Totally safe (and comfy) to wear overnight. Our heavy flow styles fit the brief perfectly to keep you feeling fresh, secure and leak-free while you get some shut-eye.
Backup
Cup runneth over? Period undies pair well with other forms of period protection, like a menstrual cup or tampon, for extra peace of mind on heavy flow days.
Rinse, Wash, Dry
Taking care of your Undercovers period undies isn’t rocket science, we promise.
- Rinse under cold water until the water runs clear
- Pop into a wash bag and wash on a cold gentle machine wash
- Line dry in the shade (eco-friendly points!)
We know it’s tempting on those lazy laundry days, but please avoid putting your Undercovers in the dryer, ironing or using fabric softener/bleach. Heat and chemicals can adversely affect the absorbency magic of your period undies.
