The updated Armour Fleece fabric is slightly heavier, but still breathable and stretchy, so it will keep you warm and allow you to move. A softer, plusher inner layer traps heat to keep you warm and comfortable. Secure zip pockets on the hands. Practical front 1/2 zip for easier dressing/undressing. Ribbed cuffs and bottom hem. Raglan sleeves. The main fabric contains at least 90% recycled polyester, excluding hems and details.
