When I read that only 19% of women bought period panties last year, I felt a bit... down. Why are we so hesitant to switch to a more sustainable option for menstrual products? Honestly, I was unsure at first too. I wondered if they’d really absorb well and stay odor-free. But my opinion has completely changed, especially after learning that a single tampon can contain as much plastic as five grocery bags. Over a lifetime, that adds up to about 57,000 bags worth of plastic. Still not convinced? Keep reading to meet the period panties that can truly transform your daily routine.
“Period panties come with a bunch of benefits,” says Susanna Unsworth, an INTIMINA intimate health expert and doctor specializing in menopause, women’s health, and breast cancer. “They’re way more eco-friendly since disposable products contain plastic and add significantly to landfill waste. While the upfront cost is higher, they’re much more economical over time because with proper care, they last for years.”
“They also offer longer-lasting protection, so you don’t have to change products as often. Once women find the right style and size, many say they’re more comfortable and less irritating than pads, which can shift, bunch up, or feel bulky.”
Since I’ve treated every cycle as a chance to test different period panties—from full coverage styles to bikinis for heavy days and thongs perfect for lighter flow—I feel confident naming the best period panties of 2025. Here are the ones you definitely need to check out!
Modibodi Classic Bikini
I switched from tampons and pads to period panties three years ago, and honestly, Modibodi has completely changed how I sleep. No more waking up at 2 a.m. in a panic over leaks, no need for nighttime tampon alarms, and I can confidently wear white jeans during the day. Goodbye to the “safety check” friend who always reassured me. These panties won’t let you down—even if you used the biggest, super-absorbent tampon before. The breathable bamboo fabric eliminates odor, and the long absorbent pad adds extra security.
Boux Avenue Medium Flow Modal Period Pants
Boux Avenue has long been my go-to for everyday thongs and (less often worn but just as loved) lace pieces. Now they’ve launched two period panties: a high-waisted style for heavier flow and a playful cut for medium flow. I wore the latter on days three and four of my last cycle, and it worked perfectly for lighter, spotting days. The sizing is accurate, but I went one size up for a bit more room around my thighs and waist. The silky fabric and lace details make them feel less like period panties, and on days when I just want comfy, roomy underwear, I’ll definitely reach for these again.
Hello Reusable Pad
Technically, these aren’t period panties but reusable pads you can wear with a menstrual cup for extra protection or instead of disposable liners on regular days. Say goodbye to sticky adhesives that ruin your favorite underwear—these fasten with a metal snap, and the double snap lets you adjust the width to fit your underwear style. The top layer is 100% bamboo flannel, which locks in moisture effectively, while the bottom is 100% organic Indian cotton, keeping you super breathable all day. In short: no worries about odor or discomfort, even if you wear them all day.
Snuggs Sunday Brief
“When I’m not on my period, I’m not really into hipster cuts. I always wear underwear that sits higher on my thigh because it makes me feel sexier. That’s why I fell in love with this new Snuggs style, which has a higher leg cut and a waist-hugging fit. It’s lightweight, super soft, and the inner lining is highly absorbent, so it can totally replace a pad or tampon.”
Modibodi x SmileyWorld Teen Hipster Bikini
Preteens face the same anxieties about periods and leaks as we do—maybe even more so, since they lack experience. Luckily, these period panties, designed in a colorful collaboration between Modibodi and SmileyWorld, offer reliable protection without extra bulk. Made from super breathable organic cotton with a stretchy waistband, they’re comfy even with hormonal bloating and check all the important boxes.
Hello Undies High Waist Period Underwear
What bugs me most about my period? Having to avoid half my wardrobe for a whole week to prevent visible panty lines ruining my outfit. Thanks to Hello’s most popular period panties in a soft, powdery shade, I can confidently wear my favorite light linen pants even in summer. And it’s not just about style: they can hold the equivalent of five tampons, making them reliable for periods, mild incontinence, or postpartum. After testing them through two full cycles, I can say they kept me dry and odor-free all day long.
WUKA Swim Bikini Bottom
Period-proof bikini bottoms? Seriously? I was super skeptical at first—actually, a bit nervous. I was vacationing with friends in the South of France, right in the middle of my period, and all I wanted was to join water sports without worrying about leaks. It was the perfect test, but the fear lingered. The first thing I noticed was how light and thin the fabric is, plus the higher leg cut. The hidden double-layer lining absorbs light menstrual flow, whether you’re in the water or on the shore. I even wore them swimming back in the UK. They dry fast, stretch in two directions for a great fit, and resist chlorine and pilling. WUKA also offers lots of other swim styles—from one-pieces to colorful bikini bottoms you can wear under your usual bikini for extra coverage. So you don’t have to give up your favorite trendy brands.
Modibodi Seamfree Thong
The first thing I noticed when I ordered Modibodi’s period thong for light flow was the size range. Available from XS to XL, it fits almost every body type. Love that! The fabric is eco-friendly, made from recycled nylon that’s softer than cotton and totally vegan. It’s also super absorbent with a high-tech moisture barrier that keeps you dry and fresh all day.
