It doesn't leak at night as pads do, it's cheap and environmentally friendly, but mainly that it doesn't dry out my mucus membranes and doesn't contain bleach and pesticides that I don't want anywhere near my uterus.
Hip hip hooray! May they improve all menstrual weeks for hundreds of years!
Thank you for making life easier for us women who travel a lot. Now I will be living on a boat for 6 months and save a lot of packing space from tampons, and can pack some more cute tops instead!
