You'll also want durability, and a 100% polyester fabric will help see to that. There's also style: you'll want tasteful, contrasting stripes that highlight the zipper, the brand, and the sleeves. Put it all together and you have the Under Armour Men's Midnight Navy/White Essential Woven Jacket, a piece that makes working outdoors as pleasant in the cooler seasons as it is in the summer. Want more? Good, because there's even a blank space on the chest perfect for adding your own custom logo.
