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.

    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.

    Wow!!

    I was nervous about ordering these as I’ve never tried leakproof underwear of any kind, but I thought it was high time I gave it a shot. I’m not even a teen…I’m a mom of 3 but I thought the teen designs were much cuter in style and color. I’m amazed at how well they worked and wish I had had these when I was a teen! Where have these been all my life?! Thank you Knix!

    Excellent underwear for my tweens. They can wear this to school and not worry about any leaks.
