Hi Jess, thank you for your feedback. We're glad you find the cotton velour comfy, but sorry to hear about the slipping issue. A couple things to note- It is extremely important to wear snug fitting cotton underwear with your pads and liners. Also, the liner is made to absorb and distribute. If we had flipped the fabric, any fluid would come back up through the top of the liner and would get everywhere. The backside of the backing is designed to be leak proof and simply would not work any other way.
