Let’s have a heart-to-heart about something that’s been an absolute game-changer for me—period pants. Just yesterday, a friend of my husband, a mother of two, asked about period panties for one of her daughters who just turned 13 and had recently been awarded her first bleed. It dawned on me that this is a question many women still have and might be afraid to try because they think they may leak or they don't work for their flow. Some even worry they might feel wet and uncomfortable while using them.
So, if you're tired of traditional menstrual products and looking for a comfortable, eco-friendly alternative, you're in the right place. Let’s dive into the world of period pants and discover how they can transform your menstrual experience 🌟.
What Are Period Pants?
Period pants are special underwear designed to absorb menstrual blood, giving you the freedom to ditch disposable pads and tampons. They look and feel like regular underwear but come with superpowers—multiple layers that absorb moisture and prevent leaks. Think of them as your reliable, comfy sidekick during that time of the month. And no, you won't feel wet while on your period.

How Do Period Pants Work?
These wonders work through a clever multi-layer system:
Moisture-Wicking Layer: This top layer keeps you dry by drawing moisture away from your skin.
Absorbent Core: The middle layer is where the magic happens, holding menstrual blood and keeping you feeling fresh.
Leak-Resistant Barrier: The outer layer ensures that you stay leak-free, no matter what.
Why Period Pants Are Amazing
So, why are these period pants so amazing? Well, first off, they’re eco-friendly. Say goodbye to the piles of pads and tampons filling up landfills 🌍. Period pants are reusable and planet-friendly. They’re also cost-effective. Sure, the initial cost is higher, but these beauties can be reused for years, saving you money in the long run 💰. Plus, they’re super comfortable. Made from soft, breathable fabrics, they offer a rash-free, comfy experience. No more carrying around menstrual products. Just wear and go! And they’re versatile—perfect for sleeping, working out, or just lounging around.
Avoiding Toxins: PFAs and More
Here's the thing, not all period pants are created equal. Some contain harmful chemicals like PFAs (per- and polyfluoroalkyl substances), which can mess with your hormones and overall health and fertility. Other nasties to avoid include phthalates, parabens, and formaldehyde. Because panties (whether they’re period or regular) are worn in a very sensitive area, it’s important to wear those made from non-toxic materials. Opt for brands that proudly state they are free from these toxins. Certified organic cotton is always a safe bet. According to Better Goods and Sustainably Kind Living, brands like The Period Company, Modibodi, Bambody, and Luna Pads are free of PFAs and other harmful substances. It's important to be picky about the brand of menstrual underwear you use because some brands have been found to contain nanosilver particles, which can be harmful to your health.
Do Period Panties Cause Yeast Infections?
Alright, let’s get into a hot topic—do period panties cause yeast infections? First, we need to know what a yeast infection actually is. It’s caused by a type of yeast naturally found on the skin. The trouble starts when this yeast grows out of control.
Yeast infections can pop up in various parts of the body like the mouth, navel, skin folds, and especially the vagina. The vagina is a perfect moisture-rich environment for yeast to thrive.
Wearing tight, non-breathable underwear can contribute to a yeast infection. Not changing sanitary napkins often enough can also increase the risk. So, what about menstrual underwear? Do period panties cause yeast infections?
What’s the Verdict?
If you’re prone to yeast infections, it’s wise to choose period panties that are more breathable and made of natural fabrics like cotton. Wearing menstrual underwear for long periods can create an environment ideal for a yeast infection, similar to lounging in your yoga pants long after class. Choosing breathable underwear can help prevent moisture from being trapped, thus preventing yeast growth. Also, if you’re prone to yeast infections, try changing your menstrual underwear more frequently.
Expert Insights
Dr. Renita White, an OB-GYN, highlights the importance of wearing breathable, well-fitting underwear to maintain vaginal health. Cotton is highly recommended as it allows better air circulation compared to synthetic fabrics, which reduces the risk of moisture buildup that can promote yeast growth. The Healthy
The risk varies depending on the material and design of period panties. Some users find that high-quality period panties made from organic cotton and designed for breathability don’t exacerbate yeast infection risks. So, the next time you’re picking out period panties, remember to go for those that keep things breezy down there! 🌸
My Lifesaver: Period Beachwear

Last summer, I discovered period bikini bottoms, and let me tell you—they’ve been a lifesaver! 🌊 I’ve never been a fan of tampons, preferring to let my flow be free. Period bikinis from brands like Modibodi and Ruby Love offer leak-proof protection, letting you enjoy the beach without worry. It's like nature’s way of letting us experience our periods as they were meant to be—free-flowing and natural.
How to Choose the Right Period Pants
When you're shopping for period pants, keep these tips in mind:
Absorbency: Match the pants to your flow—light, medium, or heavy. Some styles are even designed for overnight use.
Size and Fit: A snug but comfy fit is key. Check the size guides to get it just right.
Style: From briefs to thongs, choose what makes you feel best. Some can be a bit showy, so if you prefer underwear that doesn't show under yoga pants, research options from brands like Modibodi that offer seamless designs.
Material: Go for breathable, hypoallergenic fabrics, especially if you have sensitive skin.
Maintaining Your Period Pants
Rinse: After use, rinse in cold water to remove excess blood.
Wash: Machine wash in cold water with mild, organic, or chemical-free detergent on a delicate cycle. Skip the fabric softeners and bleach—they can mess with absorbency.
Dry: Air dry to keep the absorbent layers intact. Avoid the dryer.
To know if it's time to say goodbye to a pair, simply notice if you are having to change them more frequently. This could mean they are not as absorbent as they used to be.
How Long Do They Last?
With proper care, your period pants can last between 6 months to 2 years. Regularly check for signs of wear and replace them when they no longer provide adequate protection.
Favorite Brands
Here are some of the best options for period pants, including European brands:
The Period Company: Known for affordability and being PFAs-free.
Modibodi: Offers eco-friendly and vegan options, and they have a European website for easier access. (I personally use Modibodi, and while I don't have affiliate links, I genuinely love them. Of course, I haven't tried them all yet to choose the absolute best one!)
Bambody: Provides budget-friendly options without PFAs.
Luna Pads: Features organic cotton options without harmful chemicals.
Wuka: A UK-based brand known for their seamless designs that don't show under clothing.
Are Period Pants Right for You?
Period pants are a fantastic option for many, but they might not be for everyone. If you’re experiencing heavy flows that require you to change even heavy-duty period pants every 2 hours, it's a good idea to check with your doctor, as this could be a sign of other health issues. Also, if you’re looking for a sustainable, cost-effective, and comfortable menstrual solution, give them a try. For those with heavy flows, combining them with other menstrual products might be necessary.
So, my friend, period pants are truly revolutionizing menstrual care with their blend of convenience, comfort, and sustainability. Plus, some of them are cute enough to double as lingerie if you’re looking for something fancy 💃.
Whether you're eco-conscious, seeking comfort, or just curious, giving period pants a try could simplify your period routine and reduce your environmental footprint. And guess what? That same mother who asked about them got so excited, she said she might try a pair herself!
