    Super pad experience as a freshman college student

    I was give the flex pads at my college when they did an event. I'm using this for the second time and there most softs and most comfortable pads ever. I'm a type of person that has cramps when I'm on period and with this pad I don't feel bloated or cramps that much.

    The Cadillac of Pads (4.5/5 stars)

    I have not used a pad since I got first my period over 25 years ago. I always found other pads to be like scratchy diapers.

    I bought these right before my surgery because I could only use pads after it for a few weeks.

    This pad is almost perfect. It is extremely soft to the touch, thin, and lightweight. You do not even notice you're wearing it. Seriously. It would be 100% perfect if there was a bit more adhesive closer to the ends of the pads, and more on the wings too. I am not even mad I have left over pads from my surgery. I know they won't go to waste.

    If I was forced to only ever use pads, I would always choose this pad. It is truly the cadillac of pads.

    These are the best pads ever.

    I’ve never wore a pad that has been so soft & comfortable. It genuinely makes me happy when i’m on my period to have something so soft & comfy to wear. So many other brands’ pads have harsh chemicals in them as well & I love that these are safe!

    Quick shipping!

    I ordered these when they launched and they shipped in 2 days - literally faster than Amazon. These are the perfect size for my heavy flow days especially for nighttime.
