Reviews Summary
Customers say these period underwear provide excellent front-to-back coverage and feel comfortable throughout the day and night. Many appreciate the full gusset design that offers confidence against leaks, particularly for heavy flow days and overnight wear. Users find them soft and discreet under clothing. However, some mention sizing issues, with several noting they run tight in the waist or leg openings and recommending sizing up. A few customers report leaking at the leg openings despite the extended coverage. The cotton material is praised for comfort, though some find the high-rise cut too high for their preference.

    Best ones so far

    I prefer the front to back coverage and wish this was standard. Please bring these back in stock in all sizes so I can order more for my teen!

    Fit great

    They were on a great sale so I ordered the teen L for myself (adult) and found they fit very similar to an adult M. Great deal!

    Very comfortable

    Very very nice, my daughter said she finds sleeping on her period 100 times more comfortable as sleeping with a pad is very uncomfortable. 5 ⭐️ daughter wears small in pants but XS were perfect so they fit big.

    Good for lighter days

    The cotton is very comfy and looks great. I love the pastel purple colour. It's a bit more vibrant in person than it looks on my screen, but that could vary.

    Cotton doesn't feel as protective against leaks as the material on the other KT panties. That stuff is magic, I swear. But these are great for a lighter-flow day. No leaks, no trouble.

    Amazing! The only period underwear you need!

    I have been looking this for my daughter ever since she started her period. Regular period underwear is great but this is better! Even with regular underwear she had to wear a pad up the back and across the top at night time. Also, she loves to lounge around at home, and I had to constantly tell her to sit up so her period would stay in the area of the padding. This eliminates this problem. My only comment - which I think others have stated too - is more cheek coverage. Then, it would be perfect. This is just fine too for light day, heavy days, and all the days in between.

    Panties

    My great granddaughter loves them, because of the larger gusset. She is a stomach sleeper and a heavy bleeder

    Very Comfy Panties!

    I first decided to buy these because I love the color. I'm not a teen anymore but I'm happy I tried them. First, the color is even prettier in person, and more importantly they do not leak. Ever. I've worn them all day and never have that wet in my panties feeling. I like them so much I'm buying another!
