Frequently Asked Questions
Everything you need to know about how our period underwear works, how to choose your absorbency, how to care for them, and what makes them different.
How does period underwear work?
How does period underwear work?
Our period underwear combines ultra-absorbent materials with leak-proof layers to lock in moisture. It feels just like regular underwear but works hard to keep you protected, no matter your flow. Simply wear, wash, and reuse.
Is period underwear hygienic?
Is period underwear hygienic?
Absolutely. Our period underwear is made from high-quality, antibacterial materials that ensure hygiene and freshness. Plus, they’re OEKO-TEX certified, meaning they meet high safety standards for fabric use, free from harmful substances.
What are PFAS, and are they used in AllMatters period underwear?
What are PFAS, and are they used in AllMatters period underwear?
PFAS (Per- and polyfluoroalkyl substances) are chemicals sometimes used to make fabrics water-resistant or stain-resistant. At AllMatters, we take your health and the environment seriously, so we do not use PFAS in our period underwear. Instead, we focus on safe, non-toxic materials and rigorous testing to ensure quality and safety.
How long can you wear period underwear?
How long can you wear period underwear?
Period underwear can be worn as long as your flow allows, but for a maximum of 12 hours at a time. Some prefer to use them during the day, while others use them as extra protection along with a menstrual cup or tampon. Generally, it is recommended to use the underwear for 8-12 hours for maximum protection and comfort.
You can also use the underwear at night, for spotting between periods, or for discharge. To ensure that the underwear provides the best protection, you should regularly check if they start to feel wet or if blood is visible at the seams - this is a sign that it is time to change them.
Why We Made This
Our goal with the TENCEL™ Collection was to create go-to period underwear that feels as good as it functions. Whether you prefer the full-coverage comfort of the Brief or the flattering fit of the High Waist, each style offers breathable softness, 12-hour leak-proof protection, and a lighter impact on the planet. Most period products weren’t designed with real comfort or sustainability in mind—we wanted to change that. This collection is our answer: reusable, gentle on skin, and thoughtfully made without plastic or bulk.
