Jackman Nap Sweat Crewneck NavyThe Jackman Nap Sweat Crewneck in Navy is designed with a unique blend of materials for both style and comfort. The front and middle sections are crafted from cotton threads, while the back is made from acrylic. The special brushing technique used on the backside fleece creates a nap raised texture, similar to that of boa fabric. Please note that the back of the navy version is in the same color as the front, not olive as might be expected. Featuring
