Will be buying more!
These are incredible! I hate pads, I hate tampons, lol. Heck, I hate my period! However these undies make it more bearable! They fit perfectly (Let me give you a hint, buy them slightly smaller so they fit snug!). As long as they are snug you get no leaks while moving around. They fit just like a nice pair of undies. The absorbent crotch area is very soft and comfortable! I'm going to be buying more! I'm going to try the other styles. So far the Bikini is my favorite. I wear a size 12/14 and the L/XL is best fit for me. 1x is slightly too big for my size.

I highly recommend
I am currently at about 8 hours of using the super flow and I have not had a single leak, odor issue, or had discomfort. It does take a little getting used to free bleeding when the flow is so heavy, but they are a great investment. I got 3 pairs to switch off and go through my first 3 days easily without leaks or stinky trash from disposable pads.
Verified Purchase
Do their job well
Very absorbent. I suggest buying two pairs of different sizes at first to confirm which would fit you best. I bought two, xl and 1xl, before buying the rest I would need for my menstrual cycle.
