Minimal in weight and bulk but packs a punch for core warmth. The Grindstone Vest combines GORE-TEX® INFINIUM™ WINDSTOPPER® technology with PrimaLoft® Silver insulation to cancel out the chills on windy workdays and provide core warmth. The DWR finish allows this vest to perform double duty as a standalone outer layer or a heat trapping insulator. Highly packable, the Grindstone can be stowed away in your truck’s glove box.
