Great underwear for adults too!

I am 5'2", 110 pounds and have a lot of trouble finding underwear that don't give me a wedgie. This is because I have a small waist and skinny legs but a rather large behind so finding anything that will fit and won't ride up is always a challenge. In pants, I am usually a size 1 in juniors (if the behind area is really stretchy), otherwise I wear size 2 in petites. I bought both the knixteen boyshort and knixteen bikini leakproofs in a medium size based on other reviews I read. The boyshort fits PERFECTLY and doesn't ride up at all, stays perfectly in place! The bikini will stay in place if I am wearing pants but will ride up with shorts or a dress. I think it's because the leg holes are quite large and the material is soft and after a few hours of wearing they stretch a little and start to ride up on me. They are both quite comfortable and feel very thin, like normal undies. The leakproof function also actually works! Although I would recommend them for backup and not as a main period product if flow is heavy. I bought five pairs total to last me the week and do not regret it at all. Would recommend the boyshort!

Amazing product!

My tween daughter finds these so comfortable to wear anytime and also takes great comfort knowing that she has protection against leaks if her period starts. True to size based on the size chart. Will buy again!

AWESOME!

I’m 14, I’ve gone on birth control to lessen pms symptoms, I was spotting a lot the first few months and these saved my life, I did not want to wear a tampon/pad every day so I turned to these and man did they work! I now use them when I get my period on light/medium days just them, and then on heavy days as an extra layer in case of leaks!!!

5 Stars from my 15 year old!

My daughter LOVES these shorts so much! She has always had sensitive skin and it gets irritated when using pads, so these are her go-to on her medium to light period days! She also uses them with a tampon on heavy days, and she never has to worry about accidents. She just asked me if I could buy a few more! I only wish they were a little cheaper....
