The pad of the liner is on the inside and meant to be worn against the skin with the narrower portion of the pad in the front.The fabrics we use to cover our pads are 100% polyester, wicking, anti-microbial fabrics that are designed to keep you cool, dry, and comfortable on your rides.Ideally the liner fits so well you don't know its there; if it's backwards or inside out it will probably feel funny, indicating something is wrong.
