Style 501 Our Operator Grade heavyweight Half-Zip Sweatshirt is ideal for cold days and will protect you from the elements. It’s made from our durable and fade resistant blend of 80% cotton and 20% polyester. The half-zip stand up collar makes it easy to put on or remove while keeping out the wind. The left sleeve features a pen pocket and a zippered pocket for ID, credit cards, or other small items. The non-banded, open bottom design features side vents with a hidden hook and loop closure system. This makes accessing a holstered handgun or spare magazines possible with minimal effort. The short ribbed cuffs keep your sleeves in place without being over-restrictive. Machine wash. Imported.
