    Great! But please improve the labels.

    Super comfy, enjoyable to wear. But Knix, for the love of all that is holy, PLEASE find a way to label each pair with their absorbency level. It is downright mean to expect my hormone overloaded, cramping body to wake up and remember which pair of underwear has the right absorbency equivalent for the day. You've gotten them all down to such nice, light, non-bulky formats that it isn't obvious to my period-foggy brain which is which, and I feel like that's a pretty easy fix on your end. So please, help a girl out.

    13 y.o. Loves the comfort

    I purchased these in preparation. My daughter thinks these are comfy and are perfect for her to wear to school when she starts. These do sit a little lower on the hips than the bikini.
