High Waist Brief

I've been watching Shelby's YouTube channel for years, and I was thrilled when she partnered with Kathryn to bring out her line of sustainable period underwear. I bought one pair of underwear to test the fit and leakage, and I was not disappointed! As soon as I realized how great these underwear are, I ordered three more! I did order a size up, but I'm pleased to report that there was zero leakage on the first day of my period (the heaviest), and I was extremely comfortable all day. I used to use a cup, but it became uncomfortable for me, so for the last few months, I have been using pads (which I HATE for environmental and comfort reasons) - and I'm so excited to dump these products! I am seriously in love with this underwear! Highly recommended!

I love these! I will be purchasing more. I love the fit and material they are made out of. Very comfortable and have top tummy control if you have a tummy you want to secure in place.

I was super excited to finally try these underwear because I’ve followed you for a while now.
I was put off that the quality opening the package and it seemed very cheap esp with the tiny made in china tag. Pushing past the looks, I finally got to try them and they didn’t even last me an hour. I bled right through everything. I’m frustrated and disappointed. I don’t know if there are any other sizes, styles, or even some changes coming out eventually since this is a first time project…but it just sucks. I love seeing all you do and I will continue to follow you and look up to you as a role model. But, it sucks that the underwear didn’t work out :(

Comfortable and definitely agree with the heavy flow label! Lasted all night and only changed twice per day on a medium flow

I previously used Thinkx period underwear, and it worked fine, but it was really thick fabric and even when I sized up, it's still had a cinching effect similar to shapewear, so on both accounts, it wasn't the comfiest ever. On the other hand, trying Kayaness, I have never been more comfortable! It doesn't try to sent you in like shapewear and it's much thinner, softer fabric, which is incredible considering how much menstrual blood it's able to handle! I have pretty heavy periods but these period underwears didn't let me down once my entire cycle. I'm really impressed, definitely buying more, and telling everyone I know who menstruates.
