Every month when menstruation arrives, many women are accustomed to traditional sanitary pads. They have to carry them in their bags and change them every 3-4 hours in the restroom. Some even experience discomfort from allergies to pads every month. Others want to try menstrual cups but hesitate to start. Although this method has been familiar for a long time, it cannot be denied that there are still some inconveniences that women wish could be simplified.
This is why Period Panties have become an increasingly popular choice among modern women. They are not just a backup option for emergencies but a viable alternative that many wish to use instead of traditional pads. These are specially designed underwear that can absorb menstrual flow directly, providing comfort and ease without the constant worry of frequent changes. However, the questions that often arise are, "Can they really replace sanitary pads?" "Will they smell?" "Will they leak onto my clothes?" "Are they clean enough to prevent infections?" Sabina will delve into all these answers, along with information to help make your decision easier.
Can Period Panties really replace sanitary pads?
If you choose Period Panties with an absorption capacity suitable for your menstrual flow, they are designed with an absorbent layer inside the underwear, allowing them to directly accommodate menstrual flow without the need for additional pads on days when the flow is manageable.
However, it is important to note that each person has a different menstrual flow, and the amount can vary from day to day. Therefore, women should select Period Panties based on their absorption levels and monitor their own menstrual flow to ensure the most comfortable and confident use.
For Sabina Daytime Period Panties, they come with an absorbent pad approximately 25 cm in size, capable of absorbing menstrual flow or fluids up to 25 ml, which is equivalent to about 2-3 regular sanitary pads. This makes them a great option for days when you want to simplify the hassle of using traditional pads.

How do Period Panties absorb fluid and prevent leaks?
Many may wonder how a single pair of underwear can hold menstrual flow. The uniqueness of Period Panties compared to regular underwear lies in the structure of the absorbent layer designed specifically to accommodate menstrual flow and fluids.
Sabina Period Panties feature Leakproof 4-Layer Protection, a four-layer leak-proof pad that works together to quickly absorb and retain fluids while minimizing the chance of reverse flow contacting the skin, thus helping you feel dry and confident throughout the day.
Maximum absorption of 25 ml, suitable for lighter to normal flow days
Sabina Daytime Period Panties can hold up to approximately 25 ml of fluid, while regular sanitary pads sized around 23-25 cm absorb about 10-12 ml per pad, making them comparable to the absorption capacity of about 2-3 pads.
They are ideal for daytime use, especially on days when the menstrual flow is light to normal, or can be used as a backup for added confidence on days when leakage is a concern.
However, it is important to understand that all types of Period Panties have a limit to their absorption capacity. If the menstrual flow exceeds the panties' ability, there is a risk of leakage. Therefore, on days of heavier flow, you may need to change your panties during the day or choose products with a higher absorption level that suit your needs.
Quick-absorbing pads that dry fast, reducing dampness
Another concern about wearing Period Panties is whether you will feel wet and damp all the time. The absorbent pads of Sabina Period Panties are designed to quickly absorb fluids and dry fast, helping to reduce the feeling of wetness or dampness throughout the day.
When fluids are absorbed into the inner layer, it helps keep the top layer feeling comfortable and reduces worries about menstrual flow reversing when moving your body.
Will wearing Period Panties cause odor?
Odor is another concern that makes many women hesitant. When menstrual flow comes into contact with air and accumulates for a long time, it can produce unpleasant odors, similar to using other hygiene products.
Therefore, Sabina Period Panties come equipped with Odor Control Technology that helps manage unpleasant odors during wear, allowing you to go about your daily life with more confidence, whether sitting at work, traveling, or engaging in various activities.
Are Period Panties clean enough to prevent infections?
Using Period Panties properly is just as important as using any other hygiene product: do not allow moisture to accumulate for long periods, and ensure proper cleaning after use.
When you feel that the panties have absorbed enough fluid, you should change to a new pair. After use, rinse off menstrual stains immediately, do not leave them, and clean according to the instructions on the product label. Make sure to dry them thoroughly before using them again.
Who are Period Panties suitable for?
In reality, you do not have to completely stop using traditional sanitary pads to start using Period Panties. You can choose to use them according to your lifestyle and the different days of your menstrual cycle, such as:
Women who feel irritation or discomfort when wearing pads for extended periods.
Those who dislike the feeling of pad wings or adhesive shifting during the day.
Individuals looking to reduce the number of disposable pads used each month.
On days when the menstrual flow is light to normal and want to wear just one pair of underwear for ease.
On days when you want a backup option to boost confidence regarding leaks.
Those who travel, work, or engage in continuous activities and do not want to worry about shifting pads.
Another advantage is that since they are designed to be worn comfortably, the shape does not have to look bulky. Sabina Period Panties come in bikini styles and seamless designs that help reduce pressure on the thighs and minimize concerns about panty lines when worn with fitted clothing.
Choosing the right Period Panties makes that time of the month easier
Period Panties are not just ordinary underwear with added pads; they are another option for managing menstruation designed to address absorption, leak protection, odor control, and comfort.
For those who want to start trying Period Panties, Sabina Period Panties for daytime can absorb up to 25 ml of menstrual flow, equipped with Leakproof 4-Layer Protection and Odor Control Technology, allowing you to live more freely without constantly worrying about traditional pads.
Ultimately, there is no single method for managing menstruation that suits every woman. The key is to choose a method that aligns with your menstrual flow, body, and lifestyle, ensuring that your time of the month is another opportunity to live confidently and comfortably.
