Product Reviews by Experts


I love that this is organic cotton period underwear that can hold TEN TAMPONS WORTH, that is heaps and it’s so great to see period tech that is also safe to wear (organic). Of course the fabric tech to be able to absorb and hold that amount of liquid and also NOT SMELL is very specific and unique and not organic, but it is safely nestled under organic cotton allowing the undies to function and protect in all the ways necessary. I love so much the philanthropic angle of supporting women and girls who do not have access to period products, I can think of nothing worse and this warms my heart knowing a purchase of these undies leads to more women experiencing this dignity.


As soon as I took this underwear out of the box, I couldn’t wait to use it for my next cycle. The fabric felt so soft and comfortable and I was amazed that the ‘super’ underwear wasn’t as bulky as other bands I have tried. I love how easy they are to wash too. Period underwear are already such a great product for bleeding women. However I love that Eco Period ensure they use organic cotton which is a wiser choice not only for the consumer but also for the environment- I am certain this brand will now be the period underwear I purchase moving forward. I’d also like to add their Zero Waste policy has such a positive impact on the planet. I smiled when I saw the packaging completely plastic free.


I love the practicality of menstrual underwear- it makes me feel clean, dry and incredibly comfortable. This particular style is designed for a light flow, which makes it even more comfortable while still offering reliable leak protection and peace of mind. I also appreciated their Zero-Waste Office Practices (Plastic-Free Packaging and sourcing office supplies from sustainable brands to minimise single-use plastics) and Sustainable Product Life Cycle (They prioritise product longevity to ensure our period underwear is a long-term, eco-friendly alternative to disposables).
