    Needs Redesign

    It nauseates me that i spent so much money on these. super comfortable but 0 leak protection day or night. The absorbing part should go front to back ALL THE WAY. I had major leaking in the front because it (and all knix underwear I bought) don't go nearly high enough for me. I am so disappointed because i finally decided to invest in a bunch of knix and they are all worthless to me. Waste of money.

    Check Sizing Before Purchase

    I already had regular briefs so assumed the they would fit similarl. How wrong I was. The boxers were a good 4” bigger waistband, so check measurements before ordering.

    Tight on thighs

    I don’t have an exceptionally curvy body and yet somehow these gap at the top and are tight on my thighs. Still gets the job done. Not my favorite though. Size Large 5’10 170 lbs

    Love these need in non leak and more leak proof levels

    These are great for heavy flow days or nights. The fit it’s perfect, they don’t squeeze your thighs or come up to high. Please make more options and non leak bc I want to live in these!

    I’m a 27/28 Jean, got a medium

    Great Investment for me

    I brought these for the first time in June of 2023.

    I am coming back now to buy more because my old ones finally broke down. I love these. I got rid of all my other brands and only use these. They are so soft. I like to sleep naked most of the time but on your cycle you can’t obviously. But the material makes it feel as if I still have nothing on. They stay tight to my body. I do still wear a cup/disk/tampon with them depending on my flow, like I would with a pad but I use them as backup to catch the extra during the night or day. I have multiple pairs so I also wear my other ones to work or throughout the day. I love that they are seamless, so you can’t see them under my clothes or tight dresses or leggings and that they still show my figure so I still feel sexy around my man with them on. I took a risk when I bought them the first time and it paid off, more than I expected. I feel like these were a great investment, lasting me over 2 years. Will be a forever customer for this specific underwear.

    Could use some re design

    The dream short with a bamboo tank is my go to sleepwear. But . . . the absorbent pad doesn't come up far enough in the front (it leaked on me) so I have to wear it as a back up with a tampon when I'm having anything more than a very little flow at night. Also, PLEASE make the dream short in lighter absobencies. I tried to wear the dream short underneath a cotton maxi dress this summer and it felt (and pretty sure it looked) like I had a diaper on.
