Can You Wear Period Underwear All Day?

If you've ever asked yourself, “Can I really wear period underwear all day?”, you’re not alone. The short answer is yes — with the right design and care, high-quality period underwear can offer reliable protection from morning to night.

As a functional underwear manufacturer committed to sustainability and women’s health, we design reusable period underwear that meets the demands of real life — whether for active teens, working professionals, or overnight use. This article walks you through everything you need to know.

Know Your Flow

Understanding your menstrual flow is the first step in choosing the right period underwear.

On lighter days, standard absorbency period underwear can keep you protected for up to 12 hours. For heavier days, it's important to use underwear designed with maximum absorbency and extended leakproof coverage, especially around the sides and back.

At our factory, we offer multiple absorbency levels — from light to heavy — and have patented side-leakage technology that provides peace of mind even on the heaviest days. Our products are tested for reliability, backed by lab reports and live wear demonstrations.

Find the Right Period Underwear

Not all period underwear is created equal. Key features of truly leakproof underwear for women include:

• Multi-layered absorbent core

• Secure leakproof barrier along the sides

• Soft, breathable, OEKO-TEX certified fabrics

• Seamless shaping for all-day comfort

• No PFAS or harmful chemicals

If you're a brand looking to develop your own period care line, we offer OEM/ODM solutions with flexible MOQ, product customization, and support with US/EU certifications.

Washing Your Period Underwear

To keep them fresh and absorbent all day long, proper care is key:

1. Rinse them in cold water after use

2. Machine wash in a gentle cycle (no bleach or fabric softener)

3. Air dry—heat can damage the absorbent layers

With proper care, our period underwear can last over 60 washes—making it not only a sustainable solution, but also a cost-effective one for your customers.
