Period underwear can be worn day or night. To ensure proper protection, choose the right absorbency level and rest your head for the long night's sleep you so deserve.

Our period underwear is machine washable. Here's what you should know about caring for them.

1. Be gentle

All of our undies are machine washable. We recommend washing on a delicate cycle with cold water with delicate detergents. To keep your panties sanitized, refresh them with a few drops of tea tree oil or vinegar in the rinse cycle. In a hurry? You can hand wash them, too.

2. Let it all hang out

Hang or lay flat to dry and skip the dryer. Expect our undies to take between 6-24 hours to dry. To expedite the drying process, blot excess moisture and hang dry. Stock up to make sure you are always covered.

During exercise or physical activity, it can get a little wet (or smelly) down there. Proof offers an entire collection of workout underwear for leak protection. Built with multi-way stretch fabric that moves with your body, our underwear is ideal for movement. As an added bonus, they're designed to fight odor, too. Period or not, you can wear our leakproof underwear during exercise or physical activity.

Our period underwear is available in a variety of absorbency levels, some of which can provide enough protection to be a standalone product. As you shop, pay attention to the absorbency level and what it’s intended for.

To make sure you get the coverage you need, when you need it, we deliver different absorbency levels.
