    Love them!

    These are AMAZING! I haven’t used them on my period yet, but I have absolutely no doubt they will absorb everything and be leakproof! The panties built in are just as thick as a pad, if not a little thicker, but they are so comfortable regardless. The panties are also perfect coverage in the front as well as the back. They will definitely be leakproof. I also adore the fit! The waistband is not loose and not tight either, it’s absolutely perfect for my body, not to mention super flattering! They are so incredibly comfortable and I could honestly wear these all the time, even when I’m not on my period! If you’re hesitant to buy them, just go for it! They are 100% worth the price for sure! For reference, I am 5’6, a size 6, and weigh 150lbs.

    Best sleep shorts ever!

    I am 53 and perimenopausal. I replaced all my Knix underwear from years ago and decided to try these mini boxers to sleep in. Best decision I’ve made in a while! I love that when I’m moving around in bed I don’t have to adjust my shorts like traditional underwear and shorts. There’s no twisting or bunching or anything like that. I plan to try the longer ones next just for more coverage when running around the house. They do run a tad big. I’m 5’3” and 170 lbs. and the XL seems to have some extra room in the panty part. I’ve decided I need to get 5 more so I have a set for the whole week. These are the best purchase I’ve made for myself in a long time. I did a search online last night and cannot find anything similar on the market today. Thank you for making these amazing shorts that I never want to take off!!

    Peace of mind

    Initially I thought it looked too big until I wore it. Perfect, pretty and practical. I slept well even with heavy flow and there was no leakage!
