Revolutionize Your Cycle: Discover the Unmatched Comfort of the Period Panty Today!

Menstrual cycles can be uncomfortable and inconvenient, but recent advancements in feminine hygiene provide new solutions that promise greater comfort and reliability.

It's time to explore this innovative product and discover how it can enhance your period experience.

What is a period panty?

At the forefront of menstrual hygiene innovation, period panties stand out as a game-changer for those who menstruate. These aren't your ordinary undergarments. They blend functionality and comfort, engineered specifically to support you during your menstrual cycle.

 

Made with layers of highly absorbent fabrics, period panties are designed to hold a surprising amount of menstrual fluid – equating to multiple tampons. This impressive capacity means you can go about your day or night with an added layer of security. Different styles, from hipsters to high-waisted cuts, ensure everyone finds their perfect fit. Choosing period panties goes beyond comfort; reducing landfill waste from traditional menstrual products is an eco-conscious decision.

  • A reliable alternative to pads and tampons, providing peace of mind.
  • High-absorbency materials capable of holding several tampons' worth of flow.
  • Diverse styles and sizes, extending inclusivity for all body types.
  • A win for the environment with dramatically less waste generated.
  • Elevate your comfort and confidence, letting you focus on life, not leaks.

They represent more than just underwear; they're an empowerment tool, giving individuals the freedom to conquer their day confidently.

Period panties are like regular underwear, but they have a leak-proof panel sewn in in the crotch area. Like regular underwear, they are washable and reusable.

You can envision it like a cloth menstrual pad fused to the underwear. 

It's all made from cloth and machine washable and reusable. 

How Do Period Panties Work to Prevent Leaks?

Period panties may seem magical, but their effectiveness comes from intelligent design and advanced textile technology. The secret to their success lies in the multi-layer fabric, which is designed to keep you feeling relaxed and secure.

The first line of defense is typically a moisture-wicking layer that sits against your skin, helping you stay dry. Beneath this layer, several additional layers of super-absorbent fabric trap menstrual fluid away from your body, while a final leak-proof barrier helps prevent any potential leaks. Some period panties even feature antimicrobial properties to combat odors, ensuring you feel fresh throughout the day.

Key features include:

  • Sophisticated multi-layer construction for optimal fluid management.
  • A leak-proof base layer for added security.
  • Moisture-wicking and breathable fabrics to keep your skin dry and comfortable.
  • Antimicrobial properties to control odors and promote freshness.
  • An environmentally friendly choice with a reusable, washable design.


These panties act as a reliable fortress against leaks, allowing you to navigate your menstrual cycle with one less worry.

 

How Many Hours of Protection Can I Expect from My Period Panties?

The endurance of period panties can vary, but one thing is sure – they're built to last. Depending on your menstrual flow and chosen brand, they can provide anywhere from 2 to 12 hours of protection.

 

Lighter flows might find that a single pair comfortably lasts them an entire day, whereas those with a heavier flow may benefit from swapping pairs partway through. It's a personalized experience, and many brands offer a range of absorbency options. The best approach is to own multiple pairs, aiding in a seamless transition as needed.

  • Vary from 2 to 12 hours of protection depending on flow and brand.

  • Light to moderate flows might get all-day use from one pair.
  • Recommended to have several pairs for rotation, ensuring continuous comfort.
  • Matched absorbency levels for customized protection.
  • Awareness of your flow patterns is critical for optimal use.

 

 

Customizing your period care with these panties means tuning into your body's needs and adjusting for comfort and reliability.

How Do I Wash and Care for My Period Panties?

Following a proper care regimen is essential to keeping your period panties in tip-top shape. Starting by rinsing them in cold water to remove blood can prevent staining. This step is optional. When it's time for a deeper clean, a gentle cycle in the washing machine with cold water and a mild detergent is the way to go. Forgoing harsh chemicals like bleach and fabric softeners will extend the life and effectiveness of your panties.

If you prefer a hands-on approach, hand washing is equally effective. Once rinsed clean, let the pairs air dry to retain their shape and integrity. Store your fresh pairs in a cool, dry place until you're ready to use them again.

 

  • Rinse in cold water post-use to prevent stains. (optional)
  • Gentle machine wash with cold water and a mild detergent or hand wash.
  • Avoid using bleach and fabric softeners to protect absorption.
  • Air dry to maintain shape and prevent material damage.
  • Store in a cool, dry place away from direct heat or sunlight.

 

Caring for your panties will extend their life, ensuring they're ready to support you cycle after cycle.

It's up to you to wash your period undies with your regular clothes or separately.

The period underwear will come with care instructions, which may differ from brand to brand, so pay close attention

If in doubt, choose a delicate cycle for washing and drying (not hot).

Like regular underwear, underwear comes in many different materials and styles.

Are period panties in any way regulated?

Different countries will have various regulations on this. In the US, cloth pads are regulated by FDA rules. By extension, period panties fall within the cloth menstrual pad category. They are considered a Class I medical device, the lowest risk category.

As you can imagine, while not impossible, it would be improbable to get seriously hurt by a menstrual pad/panty!

Are Period Panties Safe and Free of Toxins?

The answer is tricky. It depends! Even well-known brands like Thinx have made news with underwear containing harmful substances like PFOA or PFAS.

We only carry trusted brands in our selection. Two brands, DominoWear and Tree Huggers, have also provided third-party lab reports showing the absence of these harmful substances.

How do you determine what size period underwear to order?

Sizing can vary significantly from one manufacturer to another, so it is important to consider the sizing guidelines of the specific brand you wish to purchase from.

Keep in mind that clothing sourced from Asia often runs smaller than items made in North America, particularly for consumers in the North American market. The cut of the clothing can also differ. For example, while simpler underwear may fit well on flatter body types, those with rounder bottoms may need period panties designed to provide more volume and comfort, such as those from DominoWear.

All of our listings include size guides. Please read the listing details or check the pictures to find the appropriate size guide.

If you have trouble locating the size guide, feel free to ask for assistance.

What not to do: If you already own one brand of period pants, do not assume you will wear the same size as another brand. Please check the measurements for waist/hip or size equivalents (DominoWear goes by US pant size equivalent).

What options are available in leakproof period underwear?

Menstrual panties come in many options! From least to most coverage, you have options:

  1. Period Thongs - for those preferring zero panty lines
  2. Period Cheekies - show a little more cheek towards the bottom of the panty
  3. Period Bikini - covers a little more in the back but stays low overall
  4. Hybrid Period Undies also exist to combine several advantages to accommodate a specific body type. An example would be the DominoWear Period Panty
  5. Period Boyshorts - generally sit below the belly button but cut straight across the leg
  6. Period Hipsters and Period Briefs - offer the most coverage. They go up higher and usually have full-back coverage

Period Underwear for Teens and Petites
Period Undies for Size 16/XL and up

Can you use washable period underwear for bladder leaks?

Yes! Reusable period panties also work great for bladder leaks and stress incontinence. Be sure to match your underwear style with your needs. Period thongs will likely not be able to provide adequate protection for stress incontinence.

Are Period Panties a Sufficient Replacement for Traditional Menstrual Products?

Transitioning to period panties may raise the question of whether they can function as standalone menstrual aids. The answer varies from person to person, but many have found that period panties can effectively replace traditional products like pads and tampons, particularly on lighter to medium-flow days.

The comfort level of period panties is unparalleled, as they are made from soft, breathable fabrics without bulky materials. Additionally, there are chemical-free and hypoallergenic options available, offering a healthier choice for your body. However, for heavier flow days, combining period panties with other menstrual products may provide the best protection.

Key benefits of period panties include:

  • Designed as a sustainable and comfortable alternative to disposable products.
  • Available in various absorbencies to accommodate light to heavy menstrual flows.
  • Provides a soft, breathable, and irritation-free experience during menstruation.
  • Can be used alone or in combination with other products on heavy days.
  • Encourages a more personalized and eco-friendly approach to menstrual care.


The effectiveness of period panties has made them a modern staple in menstrual management, and many users appreciate the freedom and comfort they offer.
