GUINNESS Classic Performance Zip Top

This lightweight half-zip jacket from Guinness is a must-have for athletes, beer drinkers, and anyone liable to occasionally break out in sweat (read: the entire planet). The polyester performance fabric is specially manufactured to breathe and to ventilate the wearer. There's also curved gold insert panels that flatter the shoulders and a cute neck trim detail, as well as the classic Guinness embroidered chest patch.
