At first glance the Chilly Fleece Quarter Zip might look like any other men's fleece quarter zip. It's not until you put it on that you realize that this one is different. You get the same great warmth as you would from a standard fleece sweater, but this fleece stretches like performance apparel. That's because these quarter zips are made from eco-friendly cotton-poly blended fabric that's made using 4 recycled plastic bottles per sweatshirt!
