Our Anti Pil Polar Fleece fabric is the best quality as it pills and stretches the least. Synthetic fleece is a knit fabric that stretches on the cross grain. It sheds water, holds body heat, but allows perspiration to escape. Fleece is comfortable and warm and survives years of abuse. Fleece is such a versatile fabric. It is widely used for sweatshirts, pull on pants, jackets, coats, cushions, blankets, throws and much more!
