Period underwear has become one of the most popular alternatives to disposable pads and tampons. It is reusable, comfortable, and sustainable – making it the perfect choice for those who value both comfort and responsibility.
But one important question is often overlooked: what materials are period underwear actually made of?
At allthingsdaysie, we focus on fabrics that are healthy for your body, gentle on the environment, and reliable for everyday use. Our underwear is vegan, free from silver chloride and biocides, and equipped with PermSafe™ Technology, which keeps it hygienically clean even at low washing temperatures.
Why Materials in allthingsdaysie Period Underwear Matter
The materials inside your period underwear determine how safe and comfortable you feel throughout your cycle. They influence:
Absorption – how much liquid can be held.
Comfort – whether it feels soft, breathable, and irritation-free.
Health – whether the fabrics are safe for sensitive skin.
Sustainability – how long the underwear lasts and how eco-friendly it is to wash.
By avoiding harsh chemicals and using high-performance fabrics, allthingsdaysie period underwear ensures effective protection while staying safe and sustainable. 😌 ♻️

2️⃣ Middle Layer – Reliable Absorption
Material: 80% Polyester + 20% Nylon
