Everything you need to know about period underwear

What Are Period Briefs?

Period briefs are reusable underwear designed to provide dependable protection during periods. They usually have a built-in absorbent layer that can hold a significant amount of fluid for both light and heavy periods, letting you go about your day with confidence.

Benefits of period briefs

• Environmentally friendly: By using reusable period briefs, you can significantly reduce your contribution to the waste created by disposable pads and tampons.

• Cost effective: While the initial investment in period underwear may be higher than disposable products, they can save you money in the long run because they're reusable.

• Comfortable: Many people find period underwear more comfortable than traditional period products, since they don't have to deal with the discomfort of pads or tampons.

• Convenient: With period underwear, you don't have to worry about running out of pads or tampons, as long as you have enough pairs to get you through your cycle.

How Does Period Underwear Work?

Our smart period-proof underwear has three layers of protection in the gusset, which is wider and longer than it would be in your regular underwear. The top layer wicks moisture and fluid down to the second layer, where it's absorbed. The final fabric layer has a thin, breathable, waterproof gel to help control any leaks. Our period underwear also uses an anti-microbial treatment to help prevent bacteria, neutralize odors, and maintain hygienic freshness.

When it comes to deciding how long you can wear period briefs, it's important to judge your personal comfort and the amount of flow you're experiencing. Most can last for 8-12 hours, but this can vary depending on your individual needs. Decided to give period undies a try? You might be wondering which style's right for you. With so many options out there, it can be overwhelming to pick one. That's why we've put together a list of the best period underwear, to make your decision a breeze.

How to Wash Period Undies

• Rinse – clean them under cold water.

• Wash – wash period briefs in the washing machine, following the care instructions on the label. Avoid using fabric softener: it can slightly reduce the performance of the absorbent layer in the gusset

• Dry - Hang them up outside or on a drying rack indoors, and let them air dry completely before wearing them again.

Can you tumble dry period undies?

It's best to hang dry your period briefs instead of using a tumble dryer: the high heat can damage the absorbent layer and elastic in the waistband.
