Buying more
I just came back to buy 2 more! I like that the pad is not bulgy where I feel like I'm wearing a diaper like some other products I've tried. These are comfortable to sleep in and had me covered throughout the night.

Comfortable and Effective
Age and hormones have made these a necessity. They are amazing, and I ordered a few pairs to use daily, but especially when traveling. Highly recommend. Sizing seems a little big to me.

They’re okay 3 stars?
I think these underwear are so soft and comfortable but if you have a heavy flow maybe use these towards the end! The coverage isn’t quite long enough (at least for me) and I still managed to leak some which sucks. If they extended the pad part up some and a little lower it would be perfect!

Comfortable fit
Comfortable fit and fabric. Great for catching small leaks before making it to the restroom.

Great product
Can run a bit large. I like them to fit snug.

Not enough coverage
I highly recommend not wearing to bed. Not enough coverage front to back. Even the heavy absorption is not enough for nighttime use. These are NOT leakproof! And if you are a little heavier in the abdomen area, these roll down and are uncomfortable. They’re almost too thin. Too much money for these.

Buying more. Worth the price. So comfy & does it's job so well.
I was so pleasantly surprised about the fabric; it feels like you're not wearing anything. It's so comfortable, and it literally holds everything, and it's such a blessing. Because God knows it's awful when you have to get stains off. I won't have to buy so many sheets anymore because I like them to stay in perfect, lasting condition.
