These heavyweight sweatshirts are made with two layers of thick, 13 oz. pre-shrunk 100% cotton fleece for warmth, and gusseted armpits for freedom of movement. The full zip front extends past the chin for added coverage in colder weather. We also added an interior zip pocket and two vertical hand warmer pockets. The oversized hood fits over a hard hat or helmet, making this warm full zip heavyweight sweatshirt the perfect choice for when youre on the job or out doing your thing. Arborwear Sweatshirts are cut for a streamlined fit. Designed so excess fabric wont get in your way, the fit allows for a maximum range of motion and is very comfortable. While other sweatshirts shrink down after a dozen trips to the laundry, our Sweatshirts will exhibit very little, if any residual shrinkage after washing. Arborwear Double Thick Sweatshirts may feel tight as you pull them on as the Double Thick layers of Cotton Fleece dont stretch quite as much as our Single Thick style. Once on, our Double Thick Sweatshirt will loosen up. If you prefer the fit of a big, baggy sweatshirt, we recommend you order up one size.
