For the times when the weather seems to be as predictable as flipping a coin, layer up with Carhartt's Gilliam Vest for Men. There is versatile comfort in this lightly insulated vest for everything from foggy, wet mornings to clear, cold nights. The outer shell has been treated with durable water repellent so rain simply beads up and rolls off your back, just like the less-than-ideal weather. The inner tight weave and low bulk fit nicely under additional layers or lie flat over long sleeve shirts.
