What Are Period Panties?

Period panties, also known as menstrual underwear, are specially designed undergarments that provide extra protection during menstruation. These innovative panties are comfortable, absorbent, and leak-proof, making them a great alternative to traditional menstrual products like pads and tampons.

How Do Period Panties Work?

Period panties have multiple layers of fabric that work together to absorb menstrual blood, expel moisture, and prevent leakage. Let's take a look at the structure of period panties:

  • Top Layer: The layer next to the skin is usually made of soft, moisture-wicking fabric that keeps you dry and comfortable.
  • Absorbent Core: This layer absorbs large amounts of menstrual fluid. Depending on the brand and style, menstrual underwear can absorb the equivalent of 1 to 2 tampons.
  • Leakage Barrier: The outer layer is usually made of breathable, leak-proof material to prevent menstrual blood from leaking.
  • How Long Does Period Panties Last?

    If properly cared for, menstrual underwear typically lasts between 6 months and 2 years. Here are some details of the factors that affect their lifespan:

    High-quality menstrual pads made of durable fabrics and well-constructed layers tend to last longer. Brands that use high-quality cotton, bamboo, or other sturdy materials offer products that can withstand more wear and tear, such as Plusock's period panties.

    The more you wear and wash your period panties, the faster they will wear out. If you have multiple pairs of panties and rotate them, each pair will last longer. For example, using them once a month versus three times a month can greatly affect the life of your panties.

    Proper care can extend the life of your period panties.

    Period PantiesHow to Choose Period Panties?

    Determine Your Flow

    Menstrual panties come in different absorbencies to accommodate different menstrual flows. Knowing your menstrual flow is the first step in choosing the right panty.

    • Light menstrual flow: Choose light absorbent panties at the beginning or end of your menstrual cycle. These panties hold about one tampon's worth of fluid (10-15 ml).
    • Moderate flow: For a moderate flow, choose a medium absorbent panty. These hold about 2 tampons' worth of fluid (20-25 ml).
    • High flow: For a high flow, choose a high-absorbency panty that can hold up to 4 tampons (30-50 ml) of fluid.

    Plusock specializes in professional compression stockings and period panties for plus-size women. Our period panties are made of 92% nylon and 8% spandex.

    Choose the Material

    Choose fabrics that are breathable, comfortable, and hypoallergenic. Cotton is soft and breathable, perfect for sensitive skin. Bamboo is known for its natural antibacterial properties, is absorbent, and is environmentally friendly. Modal is a type of rayon with a silky texture and good moisture-wicking properties.

    Style and Fit

    There are various styles of physiologic panties to meet different preferences and dress requirements.

    Leak-proof Technology

    The effectiveness of your period panties depends on their leak-proof technology. Ensure that the panty has multiple layers of absorbent, moisture-wicking, and leak-proof design.

    Choose an inner core that is highly absorbent to cope with your flow. The moisture-wicking layer should keep you dry and comfortable throughout the day. The outer layer prevents any leakage.

    Size and Comfort

    Menstrual underwear should fit snugly but not tightly. Most brands provide a detailed size guide. Measure your hips and waist to find the perfect fit. Make sure the waist and leg openings are comfortable and don't pierce your skin.

    Brand Reputation

    Researching and choosing reputable brands ensures that you get high-quality period panties. Read customer reviews to gauge the effectiveness and comfort of the product.

    Some brands also offer satisfaction guarantees or warranties for additional protection. The Plusock brand is recommended here, and you can access the Plusock website by clicking here.

    Health and Hygiene Considerations

    Maintaining proper health and hygiene ensures comfort and safety when using period underwear. Here are some things to note:

    1. Regular Washing: Rinse menstrual underwear in cold water immediately after use and machine wash them gently with mild detergent. Avoid fabric softeners and bleach to maintain absorbency.
    2. Drying:  Air dry menstrual underwear after washing; avoid using a tumble dryer as it can damage the materials and reduce their effectiveness.
    3. Storage: Ensure menstrual underwear is completely dry before storing it in a cool, dry place to prevent mold and mildew.
    4. Usage Recommendations: Change menstrual underwear every 4-8 hours based on your flow, keeping multiple pairs for easy rotation and optimal hygiene.
    5. Skin Sensitivity: Opt for hypoallergenic menstrual underwear without added chemicals or fragrances to prevent skin irritation, especially for sensitive skin.
    6. Health Monitoring: Be alert to any signs of irritation or infection. If issues arise, switch brands or consult a healthcare provider.
    7. Longevity and Replacement: Inspect and replace menstrual underwear when they show signs of wear or reduced functionality to ensure hygiene and effectiveness.

    In summary, period underwear is a reliable, comfortable, and environmentally friendly alternative to traditional menstrual products, designed to address both environmental concerns and the personal needs of users.

    They offer benefits such as enhanced comfort, effective leak protection, and chemical-free options while being versatile, making them a practical choice for menstrual care.


    Are Period Panties Safe?

    Period panties are safe and beneficial, made from natural, chemical-free materials that prevent skin irritation and reduce the risk of Toxic Shock Syndrome (TSS). They are hypoallergenic and maintain hygiene with regular washing. Their comfort and reusability also support environmental sustainability and personal well-being.

    Are Period Panties Worn Alone?

    While menstrual panties offer many advantages, we recommend that they are safer and more hygienic when used in conjunction with a tampon, for example. And change your pampers/tampons once every 3-4 hours.

    How to Wash Period Panties?

    To wash period panties, first rinse them in cold water to remove blood, then machine wash on a gentle cycle with mild detergent. Avoid bleach and fabric softener, and air dry instead of using a tumble dryer. For stubborn stains, spot treats with a gentle stain remover. Proper care extends their lifespan and maintains effectiveness.

    How Long Does Your Period Last?

    Menstruation is the duration of a woman's menstrual period. It usually lasts from 2 to 7 days, mostly from 3 to 5 days.

    The first day of bleeding is the beginning of the menstrual cycle, and the time between the first days of menstruation is called the menstrual cycle. The normal menstrual cycle is 28-35 days. It varies from person to person. As long as it's regular, you don't have to worry about it.

    Menstruation is not only monthly, but also quarterly (once every three months), bimonthly (once every two months), and annually (once a year).

    How Small is a Normal Menstrual Period?

    Between 20-80mL is normal. You can usually tell by how much is on your diaper. For example.

    • Mild: less than 1/3 of the entire napkin; Moderate: 1/3 to 1/3 of the entire napkin; Moderate: 1/3 to 1/3 of the entire napkin. 
    • Moderate: 1/3 to 3/5 of the entire napkin.
    • Severe: the blood stain is almost all over the napkin.
