1. How does period underwear work?

Period underwear is specially designed to catch menstrual blood through multiple absorbent layers. As shown in this picture from Cheeky Pants. Cheeky underwear consists of 4 different layers, each with its own function.

• The innermost layer, also called the top layer: to ensure the underwear feels dry and fresh, the top layer is made of a moisture-repellent material. Menstrual blood can pass through, but the underwear doesn't feel wet all day while wearing it.
• The absorbent layer: this absorbs the menstrual blood. The absorption capacity can vary by brand and type of underwear. The average period underwear absorbs up to about 2-3 regular tampons worth of blood. For heavier periods, there are also specific models with more absorption.
• The leakproof layer: a moisture-proof lining that ensures blood cannot leak through. This keeps you protected all day!
• The outer layer: this layer is made of breathable fabric and makes the underwear look like normal underwear! It's available in various models, designs, and colors

2. How much blood can period underwear absorb?

The absorption capacity varies by brand and model. Most period underwear has an absorption capacity of about 20mL. Cheeky Pants underwear has an average absorption capacity of about 2.5 regular tampons. For heavier periods, it's recommended to order extra absorbent period underwear.

Which absorption capacity is right for you? Compare it to the absorptive capacity of a tampon:

• Mini tampon: 6-8mL
• Regular tampon: 8-10mL
• Super tampon: about 10-12mL

3. Can I wear period underwear all day?

Depending on the heaviness of your period and the absorption capacity of the underwear, you can typically wear it 8 to 12 hours without risk of leakage. After 12 hours, it's recommended to change into a fresh pair of period underwear, even if the absorption capacity isn't fully used. But in principle, the underwear can be worn all day and for all your activities!

4. Is period underwear suitable for wearing at night?

Yes, period underwear can be worn at night and provides protection against leaking during sleep. Cheeky Pants underwear generally has absorption capacity from the front seam to the back seam of the underwear! This makes it suitable for activities throughout the day and for a worry-free night's sleep.
