Reviews Summary
Customers say these shorts are comfortable, soft, and provide excellent overnight protection without leaks. Many find them perfect for sleepovers, school days, and sleeping, giving confidence during heavy flow periods. Users appreciate the smooth feel against skin and cute patterns. Several mention sizing up for better fit, as they tend to run snug. Some note the waistband can feel tight, and a few wish the protective area extended higher in the back. Parents frequently buy multiple pairs after initial success. Common feedback includes easy washing and the ability to wear them during the day or night for reliable, comfortable protection.

    I’m 50 !

    I’m 50 years old and petite… I prefer these! I wear them everyday! I love them. I have a street wear style, long baggy shorts and tanks. These are the perfect most comfortable underwear I have ever worn in my life! I have tattoos all over and purple pink whatever hair color. Thongs and femininity is not my thing. With that said, I’m EVER SO GRATEFUL for these undies! Colors and ALL! I’m 5’3 115 Size Medium is PURRRRFECT! Keep making fresh colors! 🤟🏽

    Perfect fit

    Just as described. Great overnight coverage. Comfy too.

    My only wish…that all Kt undies have the product name and absorption level printed on them. It’s hard to identify the level just looking at the garment.

    Great sleep shorts!

    Bought these for my 17 year old daughter and she loves them! No more surprise leaks during the night and they are very comfortable. She found fit to be true to the size chart.
