Period protection is not one-size-fits-all. Your flow changes across the week. Your days are not identical either. Some are long and packed, others are slower. Some nights are uninterrupted, others are restless.
Choosing the right leakproof panty doesn't have to be complicated. A simple way to decide which of Mahina’s period care is the best fit for you is to gauge how many times you change your product in 12 hours, then adjust based on what your day or night looks like. Think of it as a quick flow check followed by a quick routine check. Once you understand those two things, the decision becomes far more straightforward. Before that, let’s dive into the basics.
What Is Period Underwear And How Does It Work?
Period underwear is underwear with an in-built absorbent gusset that manages menstrual flow without the need for pads, tampons, or cups. It looks and feels like regular underwear, but the protection is built into the fabric itself.
Mahina’s period underwear uses a three-layer absorbency system to manage flow and keep you leak-free. The top layer sits closest to the skin and helps manage moisture so you don’t feel wet and uncomfortable. The middle layer absorbs and holds the flow securely within the core. The bottom layer forms a leakproof barrier, preventing stains on your clothes.
Which Absorbency Level Should You Pick Based On Your Flow?
Use what you typically go through in around 12 hours as your baseline. That gives you a practical reference point.
Light
If you usually go through about 1 pad or 1 tampon in 12 hours, or fill up about half a menstrual cup in the same window, Mahina’s Daily Panty Liner Underwear (DPLU) is likely sufficient. DPLU is best used for light flow, spotting, daily discharge, or even as a sweat-absorbent panty.
Medium
If you typically use about 3 pads or 4 tampons in 12 hours, or fill about one menstrual cup in that time, medium absorbency aligns well. This is often the right choice for regular flow days when you want steady protection without moving up to the highest capacity.
Heavy
If you tend to change, say 4 pads or 5 tampons in 12 hours, heavy absorbency offers more margin. This also works if you fill up about two cups in that window, and it is best for heavy flow.
Super Heavy
If you go through roughly 5 pads or 7 tampons in 12 hours, or fill up about 2.5 cups in that timeframe, super heavy absorbency provides the highest level of absorbency. This level is best if you have PCOS-related heavy flow that can be tough to deal with, which makes it an excellent overnight period underwear as well, helping you get uninterrupted sleep. Mahina’s range of period underwear has a panty, ready for any occasion. And to make it easier, simply locate the “Flow Guide” chart when shopping, and it is easy to decipher.
How To Pick Mahina Based On Your Routine
Once you know your baseline absorbency from your usual 12-hour pad or tampon count, the next step is to look at your day. Routine does not change your flow, but it changes how much margin you may need. Think of this as a simple decision guide.
If you will be away from a bathroom for long stretches
Start with the absorbency that matches your usual pad count in around 12 hours. If you are unsure or expect limited access to breaks, move one level up.
The reason is practical. When you cannot change easily, you want an additional buffer built in. That extra margin reduces the pressure to time your breaks perfectly and allows you to focus on work, travel, or classes without constant calculation.
If it is an overnight situation or travel
If you’re travelling or want some quality sleep, aim for super heavy absorbency. Choose Heavy or Super Heavy based on your 12-hour baseline. If you are between two levels, lean towards the higher one.
When you are lying down, flow can distribute differently compared to when you are upright. You also cannot check or adjust as you might during the day. This is where overnight period underwear becomes useful. It offers extended coverage and higher capacity so you can rest without interruption.
If it is a light day, spotting phase, or daily discharge
For days when you just need basic protection, choose Mahina’s DPLU instead of reaching for a higher capacity than you need.
On lighter days, comfort and simplicity matter more than maximum absorbency. It replaces 4 disposable panty liners in 1 wear, helping you keep your routine uncomplicated.
To make the decision even simpler, take Mahina’s Know Your Flow Quiz. It’s a quick 2-minute quiz that helps you understand your flow better and choose a set of panties tailored to your cycle. It takes the guesswork out of choosing and gives you a clear starting point.
Build Your Own Rotation
Most people do not need a single absorbency level for the entire cycle. It is common to switch between heavy and super heavy for a couple of days, and opt for light towards the end. Some prefer super heavy as overnight period underwear while keeping heavy for daytime wear.
Use the 12-hour flow guide as your reference point. Adjust based on how long you will be out or how your nights tend to feel. Over time, you build a small rotation that mirrors your cycle.
When the right pair matches both your flow and your routine, your period becomes easier to manage, and you can get on with the day without worrying about product changes.
