Best Period Panties for Women of 2026

"I was honestly skeptical about period underwear until I tried Knix. The boyshort style is flattering, the fabric isn't bulky, and they're incredibly comfortable—I even wear them to bed for extra protection. I haven't used them alone yet since I have a heavy flow, but as backup, they give me peace of mind. I appreciate the quality and seamless look under clothes."

"These are now my go-to panties! The soft, stretchy fabric fits perfectly without sagging, and they're thin enough to wear under dresses without looking bulky. I love how comfortable they are for daily wear. They're a bit pricey, though, which is my only complaint, but otherwise, they're fantastic."

"For me, the comfort and breathability are top-notch compared to other brands. The material stays stretchy after washes, and I feel protected from leaks. I do wish I'd picked a smaller size, as the fabric loosens up a bit, but the overall fit and performance are excellent."

"I've found these period panties to be extremely comfortable and soft, and they absorb well without being too bulky. I especially value the full coverage and lack of visible lines, making them my top pick compared to other brands I've tried."

"The fabric feels amazing, almost like I'm not wearing anything at all. They do a great job of preventing stains and leaks, which is a huge relief for me. I appreciate not having to worry about my sheets anymore."

"While I love how soft and comfy these are, I would recommend them more for light days or towards the end of a cycle. For heavier flows, the coverage isn't quite enough for me, but if the pad area was extended, they'd be perfect."

"I've found these period underwear to be super comfy and not too thick. They fit just like my regular underwear and I haven't experienced any leaks despite having a moderate to heavy flow. I really appreciate that they don’t shrink in the wash and there’s no lingering smell or stains to worry about."

"After using these for over a year, I can say they’re very reliable for unpredictable cycles and I love the peace of mind they give me. They’re durable with regular washing, though after a year, I did notice some wear at the pad seam. Sizing down helped them stay in place better for me."

"These are exactly what I wish I had as a teen! My daughter wears them for all her sports—cross country, basketball, and golf—and says they're comfortable and work flawlessly."

"I’m so happy with these—the comfort and fit are unmatched and the coverage is just what I need. Even though they’re a little pricey, the quality makes it worth it. The boy leg design is also a huge plus for me."

"After trying both Thinx and Knix, I chose Knix for my last purchase. I find Knix absorbs better, and I never worry about leaks—even overnight. They stay comfortable wash after wash, especially when I use the included mesh bag. I’ll definitely be picking up more in the future!"

"Working long shifts as a server, these have been a lifesaver. I feel secure and comfortable even on busy days when I can’t always run to the restroom. No more anxiety about leaks, big or small—these really make a difference!"

"I love how soft and comfortable these underwear are, and I feel totally protected from leaks all day long. No panty lines show under my clothes, and I don't have to worry about accidents, even when I'm not sure if my period is coming. They're also really easy to wash and stay soft after cleaning."

"As someone with a teenage daughter on a swim team, these period underwear have been a lifesaver during practices. She wears them under her swimsuit with no leaks and no visibility, and the quality is outstanding. I feel so much better knowing she’s covered."

"The absorbency impressed me—I tested them with water and they held up incredibly well with no leak-through. The material is stretchy, soft, and smooth, and the fit is perfect for my XXL size. While they're a bit pricier than other options, the comfort and peace of mind make it worth it!"

"I finally decided to try these and I'm so glad I did. They’re incredibly comfortable, don’t move around, and look almost like regular workout shorts. They’re definitely leak-proof—I can sleep through the night with no mess at all."

"I work 12-hour shifts and these are a lifesaver. Lightweight but with enough padding to last all day, fit as expected, and solve my leak issues on heavy days. They wash well and barely smell. Comfort and reliability in one!"

"Honestly, I was surprised to only get one pair instead of three. Quality is good and they’re comfortable even on heavy nights, but I do wish the listing was clearer about quantity. Absorption is impressive and there’s no leaking, but for the price, I’m hoping they last a long time."

"After trying these out, I found the comfort and secure fit for my belly and butt outstanding. The beige pair, in particular, is perfect, with a smooth, non-lumpy feel and excellent support. I followed the sizing chart and my medium fits like a glove. Even though they're a little pricey, they're absolutely worth it for the functionality and comfort."

"I was skeptical because of the cost, but once I got them on sale I was amazed. No rolling down or riding up, and they're high-waisted so great under dresses. I feel secure all day and don't have to rely on pads for backup. I'll definitely be looking for more, especially since these solve the problem of leaks on heavy days."

"As someone who deals with bladder leaks, these have been a game changer for me at work. Comfortable, lightweight, and reliable for minor leaks—I actually forgot I had them on! For the first time in years, I didn't need a pad to stay dry. They're not cheap, but the freedom from pads is worth every penny."

"I've tried several brands of period underwear over the years, and these are by far my favorite. The high-waist design gives me the belly support I need when I'm bloated, and the coverage is amazing—from the pubic bone all the way up the back. They're comfortable, don't bulk up under clothes, and I can even use them under dresses to prevent thigh chafing. Highly recommend for anyone looking to ditch panty liners or needing backup protection!"

"After spending a lot on different postpartum underwear, I finally found a pair that works for me. These are breathable, made with mesh material that's perfect for postpartum sweats, and the boy short style is a game changer. The pad area offers full coverage and even looks like athletic shorts rather than typical underwear. Zero leaks, super absorbent, and no itch or discomfort like other brands."

"Comfort-wise, these period panties are great, but I did experience some leakage along the thigh seams after a short drive. They work well for spotting or light days, but might not be enough for heavy flow. I think they'd be better if the absorbent area extended further toward the thighs."

"I'm impressed with how the absorbent panel extends from the front to the back waistband, providing me with fantastic coverage. After using these, I see why they've become so popular. The waistband stays put, and the material is silky yet supportive. For me, the fit was perfect based on the size chart, even though I don't usually wear XL. These are easy to care for, and the price feels very reasonable for what you get."

"As someone with a super heavy flow, I appreciate that the absorption panel is higher in the front and the material is thicker compared to name brands. While I still need a tampon on my heaviest days, these are great for the rest of my cycle. I'm a size 22/24 and the 4X fit well, though I could have sized up. If you're plus size, consider going up a size."

"I love that these are comfortable, soft, and well-constructed. The protective area covers most of the front and all the way up the back, which is perfect for overnight use. On lighter days, I haven't had any leaks, but during heavy flow, they can leak after a couple of hours. Still, the no wetness or lingering odor is a big plus for me."

"I'm seriously obsessed with how soft and comfortable these period panties are. They’re super absorbent—I slept in them all night on a heavy day and had zero leaks. Came back for more after my first purchase!"

"After trying several brands, these have become my go-to period underwear. I love the wide gusset, which means I don’t have to worry about leaks on the sides like with other brands. They’re also really comfortable and absorbent."

"The material on these is incredibly soft, and the unique stitching really stands out compared to anything else I’ve tried. The fit is just perfect—so comfortable I sometimes forget I’m even wearing period panties."
