What Is Period Panty? All You Need to Know
Menstrual care has come a long way from sanitary pads to tampons, menstrual cups, and now period panties. Wait! What is a period panty?
A period panty is an intuitive underwear option for preteens who are still getting used to the changes in their bodies. It's similar to normal underwear, besides the fact that it's designed to absorb all the menstrual flow. They are created for comfort, convenience, and long use without having to worry about changing them, leaks, or discomfort. As a result, period panties can either completely replace your pads and tampons or support them better. Thus, making them a popular choice today for young girls as well as women.
This Plan B article guides parents and girls towards comfort-first essentials during menstruation. It explains how a period panty works, its types, benefits, usage, and safety. Towards the end, the guide also answers some of the commonly asked questions related to period panties.
How Does a Period Panty Work?
It’s natural to ask, "What are period panties?", "How to use a period panty?", or “What is period underwear?” If you’re wondering, "How do period panties work?" you aren’t alone; the concept of period underwear is fairly new. Below is a detailed understanding of what is a period panty and how it works:
-
What is it: For starters, period panties or period underwear mean the same thing. It is an undergarment that absorbs your blood flow, just like pads. Unlike a menstrual cup that requires insertion, which may not be very comfortable at first, period panties fit and function just like any regular girls' underwear. Put on a pair when you are menstruating and let it absorb all the flow.
-
Uses a Layered System: Period underwear has a 3-layer mechanism. Sanitary pads start to feel damp, itchy, and uncomfortable after some hours. They are not great at keeping you dry and often result in rashes. Period panties have a special moisture-wicking top layer. It keeps the wetness out, and there is no contact between your skin and the moisture. So, no rashes! Just under this moisture barrier is a built-in absorbent core that traps menstrual blood. At the bottom, there is a leak-proof outer layer made from breathable and protective fabric sheets. It does not allow blood to leak and keeps your pants stain-free.
-
Absorbency Range & Wear Time: You can wear a period panty for light spotting as well as heavy blood flow. It will keep you safe for 8-12 hours, even while you are fast asleep.
-
How to Use a Period Panty: There are two ways to use it. One, you can use it as it is. Two, you can use it with a cup/tampon to manage heavy flow.
-
Beginner-Friendly: Period panties are a great way to build healthy menstruation practices in beginners. So if your tween is adjusting to their menstrual cycle, try pairing a Plan B period panty with a cup/tampon for added reassurance.
Wondering “what is the price of period panty?” They can run you between Rs 200 to 1000 depending on the quality. The disposable ones are typically cheaper than the reusable options.
Types of Period Panties

Period panties come in a variety of styles. Why? To honour the varying flow levels, lifestyles, and comfort needs of girls. Below is a detailed understanding of the different types of period panty for girls and period panty for women that you can explore. This includes information about a reusable period panty as well as a disposable period panty.
Reusable Period Panty
A reusable period panty is a washable, breathable, and eco-friendly way to manage your blood flow. You can wear, wash, and rewear them multiple times throughout the cycle.
These panties are made from high-quality, breathable materials. As a result, you can wear them for long hours. Moreover, the panties do not lose their shape or form with gentle use. You may worry about the odour. But aside from a mild metallic scent, which is common to menstrual blood, there's no lingering smell after cleaning.
Each reusable period panty can last anywhere between 2 years and 3 years with adequate care and proper washing, giving you both comfort and long-term value for cost and eco-friendliness.
For young girls just starting their menstrual journey, having 3–5 pairs of period panties is a great starting point. It will keep you comfortable and covered throughout your cycle.
Disposable Period Panty
A disposable period panty is created for single use. You can immediately dispose of it after use. This makes them a great choice during travel, camps, and emergencies when a backup is important.
There’s a catch! They are convenient but lack eco-friendliness because of disposal practices. They’re also costlier because of the single-wear design.
By Flow Type
The capacity of a period panty to absorb your flow without leaking depends on its absorbency levels. A Plan B period panty has suitable selection for light, moderate to heavy flow days. From a spotting panty for light flow to reusable panty for heavy flow, there’s a right fit for every need. Plan B’s collection pack that includes panties suited for both light and heavy flow will keep your little girl ready for everyday.
By Fit & Style
When it comes to periods and managing your blood flow, fit and style play a very important role. You will commonly find these 3 styles in girls underwear:
-
Briefs: These period underwear give you a smooth, seamless fit, staying invisible under clothing. So no awkward lines or seams are visible to others. As a result, they are great for wearing yoga pants and office wear.
-
Hipsters: They sit low on the waist and moderately cover your front and back. They’re perfect if you want a balance of comfort and style.
-
Boyshorts: Boyshorts give you extra coverage and freedom to move without worry. Their extended cut ensures better protection and a relaxed fit, making them ideal for active days or overnight wear.

Benefits of Using a Period Panty
Pads and tampons have existed for years now. Although they are moderately reliable for periods, these traditional menstrual products have their own unique challenges that period panties manage to solve. For example, dampness, bulky form, heaviness once they’re full, odour, staining, and more.
Yes, the idea of a period panty for girls may seem weird, especially if your girl has used a tampon or a cup before. And she may have to spend some time with it before she gets used to the feeling of the free flow. But once she does, there may be no going back.
Here's why choosing period underwear is a great choice for your flow days:
-
Leak Protection For School, Travel, Sports: A pad starts to feel wet after some hours and is not always leak-proof. But period panties are created to trap menstrual blood securely and leave behind no stains. Thus, making them ideal for use during school hours, travel, and sports activities.
-
100% Comfort: Soft and breathable materials make a period panty feel like regular underwear. What does this mean for you? No bulky feeling or the need to readjust every now and then. Plan B period panties are easy to wear and super effective. They have a leak-proof fit and a stain-free inner lining so that you can go about your day worry-free!
-
Move Around Confidently: The extra layers of microfiber polyester in period panties absorb blood and prevent moisture from making contact with your skin or leaking out. This reduces anxiety about stains.
-
Sustainability: Pads and tampons are not reusable. They must be restocked for every cycle. Moreover, disposing of them safely is a concern. Reusable period panties cut down on disposable waste, making them eco-friendly.
-
Cost-Effective: A reusable period panty for girls and women can last you anywhere from 6 months to 2 years, depending on your care and wash cycles. You don’t have to buy a fresh pair for every use. These small savings in period panty price compound in the long run.
For teens starting their cycles, Plan B's period panty for girls is a confidence-boosting essential, made with care and comfort in mind.
