Molded Perfectly

At first I was a little worried at how thick the actual gusset pad was, to be honest it threw me off for a moment. But once I put it on, it seemed to just mold to my body perfectly.

Good quality

I ordered 3 styles of the underwear, all very comfortable. It does feel similar to wearing a sanitary pad but a lot cleaner and more comfortable. I use the underwear as a backup to the diva cup and I haven’t had any overnight leaks ruining my sheets which is such a nice change.

First wash went well, tossing them in with the rest of my laundry felt very strange but everything came out clean! If these continue to wash well I’ll be completely Satisfied with the purchase, we’ll worth the money.
