6 Major Differences Between Period Underwear And Your Regular Undies

Every woman dreads their time of the month. Headaches, menstrual cramps, diarrhea, hormonal fluctuations, cravings, lower back pain are just some of the things you’ll experience when you’re on your period. Although they’re inevitable, you can make your menstruation more comfortable and less stressful with the right period products.While your period is an unwanted monthly guest, keeping good menstrual hygiene management is still paramount for your health. Your monthly period supplies greatly affect your lifestyle during those days. Pads and tampons help women survive their menstruation, but changing them several times a day is uncomfortable and irritating. Women need better options that can redefine their menstruation experience.

Thankfully, innovative products like Knix period underwear are here to save the day. Period underwear isn’t like your ordinary undergarment, because it focuses on worry-free protection against period blood, sweat, and pee, day and night. Take a look at how they’re different your traditional undies:

  1. Superior Absorbency

To combat your period worries successfully, you have to find the product that can absorb your menstrual fluids seamlessly without creating any mess. Unfortunately, typical undergarments are no good for this as they lack what period panties have: absorbency.

Period panties consist of additional absorption layers that absorb and collect menstrual fluids. Traditional underwear typically has only two layers. Take note that reliable absorbency doesn’t depend on the number of layers, but its quality. Period underwear layers use microfiber polyester, lycra, and nylon, and many companies even feature their own patented technology.

  1. Better Support

Period panties aren’t created equally. Some of them have a larger fluid capacity than others, ranging from one to eight teaspoons. Period panties with lower capacity usually act as support for the main period product used, and they can hold leaks better than ordinary underwear.

For instance, menstrual cup users with extremely heavy leaks can wear period underwear to supplement their menstrual cup. Those with active lifestyles might not have enough time to empty their cup from time to time. Period underwear collects leaks and ensures that the blood won’t show, unlike normal underwear.

  1. Antimicrobial and Odor-Free

Conventional underwear can be made from a variety of materials: cotton, spandex, polyester, and nylon. But some companies compromise comfort for style and design their undergarments with unideal fabrics. When choosing any underwear type, always go for cotton due to its excellent softness, breathability, and comfort. Synthetic fabrics like polyester, nylon, and spandex aren’t ideal for your vagina, as they trap moisture and heat—making that area the perfect breeding ground for bacteria.

Since period panties are solely designed for collecting menstrual blood and prevent them from leaking out, they’re crafted with materials that offer breathable and odor-free properties. After all, blood exposed to air isn’t a pleasant smell. Also, using pads with ordinary underwear during your period is uncomfortable, especially if your underwear is tight and non-breathable. Whether you’re in your period or not, always avoid tight, restricting clothing as it can trigger or worsen vaginal yeast infections.

  1. Hassle-Free Washing

The technology integrated into designing period underwear also makes washing them easier. Compared to ordinary underwear, period underwear highlights stain-resistant fabric where blood doesn’t settle and dry out while wearing it.

Also, no matter what color of period underwear you’re wearing, period undergarments usually have a black layer on the crotch part that collects the blood. Since blood doesn’t set easily on period underwear, you can wash them as easy as 1-2-3. They can either be hand- or machine-washed.

  1. Comfortable Fit

Regular underwear, particularly those made from synthetic fabrics mentioned earlier, often triggers chafing and skin irritation. If you’re used to wearing ill-fitting underwear with or without your period, stop immediately. Period underwear are made from soft and delicate fabrics that don’t cause friction between your legs. Also, the menstrual blood collected on your period panty won’t get in your way whenever you’re sitting down.

Depending on your flow, you can pick a comfortable fit that can hold your flow. Thong-style period underwear, which are relatively smaller, can hold less than full-coverage period underwear.

  1. Value For Money

While period underwear are more expensive than traditional underwear, you can get the most of your money’s worth.

The prices of ordinary underwear can vary greatly from cheap to high-end ones. Despite how affordable or expensive they are, they won’t hold up against accidental leaking or staining. They also won’t look the same as before despite washing, and you might end up throwing them away.

On another end, period panties are undoubtedly expensive, but they’re expensive for good reason. Their manufacturers developed special technology to provide the best experience for women on their periods. Period panties are washable and reusable for up to two years, saving you a lot of money from purchasing other period products and buying replacements for your stained undergarments.


Upon hearing the word ‘menstruation,’ many women associate it with discomfort and inconvenience because they haven’t found the best period products yet. By incorporating period underwear, instead of regular undies, into your monthly menstruation routine,  you can guarantee safe, comfortable, and fun red days.
