    Great pair for a heavy flo

    These underwear were exactly what I needed for the first two days of my period. I just started making the full switch over to period underwear, as before I was half and half, and these underwear make that possible for me with no leaks!

    Leaky sides

    There is no support on the sides of the underwear. If you use it as your primary support during your period, you may end blood on your pants or whatever bottom you are wearing.

    Great in use- bad in longevity

    I was so ecstatic to learn that Knix was coming out with these underwear. When new- they are amazing and i have never had any issues with them. The problem comes after washing them and repeated use, they are quick to fall apart and become useless. Out of my last batch 6 months ago- only 2/8 have lasted. While i will continue to use them because the benefit outweighs the cons. That being said- for those on a small budget- the cost of continual replacements could become expensive.

    Peace of Mind

    I've worn these solo, with a pad, for sleep, for exercise, for security the day before my period's scheduled start... I can't remember the last time I felt so protected and worry-free. And they're comfortable! For fellow 51-inch waist girlies, XXL is just right. You'll think it's going to be snug, but after a single wash and wear they fit like all underwear ought to. And the absorbency/coverage is exactly what a heavy bleeder like me needs for peace of mind through the day or night. I will say, because I'm a REALLY heavy bleeder during the day, pairing with a pad for the first few hours or so seems to be the best way to avoid overwhelming the absorbent layer before the day is done. Will definitely recommend to my heavy-flow friends.
