In an era where sustainability and eco-consciousness are paramount, the products we use during our periods deserve thoughtful consideration. When it comes to period underwear, the differences between generic supermarket period undies—like those found at Coles and Woolworths—and Eco Period underwear are striking.
In this article, we break down the distinctions between supermarket period underwear and our Eco Period range by comparing size inclusivity, material quality, design, and absorbency performance.
Unlike many supermarket period undies, Eco Period undies are proudly size inclusive, offering a broad range from size 6 to 26. We believe every person deserves period products that make them feel confident and supported—regardless of body shape.
In contrast, Coles period undies and Woolies period underwear typically come in limited sizing, which can make finding the right fit a challenge for many shoppers.
Eco Period underwear is made with certified organic cotton—a breathable, skin-friendly, and sustainable material that supports both your body and the planet. This quality fabric reduces exposure to harmful chemicals and enhances long-term comfort.
On the other hand, many supermarket period underwear options focus on affordability, often compromising with synthetic materials that lack the breathability and softness of natural fibres.
Eco Period undies are designed to feel good and look good. With thoughtful design touches like lace trims and soft-stretch waistbands, our styles offer comfort without sacrificing confidence. They’re made for real life—school, work, or sleep.
By comparison, Coles and Woolies period underwear often prioritise basic functionality, with limited options in style or body-contouring fit.
At Eco Period, we go beyond claims—we test our products. Our underwear is lab-tested for absorbency, with options that hold up to 60ml (that’s more than 3 regular tampons!). This gives you peace of mind that you’re protected throughout the day or night.
In contrast, most supermarket period undies don’t advertise verified absorbency levels, leaving customers unsure of what they’re really getting in terms of protection.
While Coles period undies and Woolies period underwear offer convenient access during your weekly shop, Eco Period undies deliver a premium experience in comfort, reliability, sustainability, and size inclusivity.
Choosing Eco Period undies means making a conscious decision to support sustainable products that truly perform. Whether you’re managing your period at school, at work, or overnight, trust in underwear that’s been tested and loved by thousands of real users.
