Similar to RAW Hoodies this new Heavy series uses rowdy 17.5 oz 80% cotton / 20% polyester blend fleece to turn you into a snuggle monster. (PS Chix Dig It) The extra little touches are still there including thumb holes in the cuffs and 4" x 4" loop fastener fields for your cool guy patches. As a bonus on this version there is an interior stash pocket in the right muff pocket to hold a music device and even a headphone port hole to rock out in warm comfort. A big ass metal zipper is used for long term durability. We call it econo since they are imported and we got a crapload of them so we can offer them at a good price. On that subject, the factory must have thought we were all fat American bastards so the sizes run BIG. It is recommended to choose one size smaller than you usually wear and even then it will be a loose fit. If wanting a more fitted look, go 2 sizes down. Note due to the high cotton %, expect a little shrinkage after the first wash.
