Awesome cool weather base layer
This thing does exactly what it's supposed to... I just wore it every day on a 5 day backpacking trip and it kept me dry on the way up, and warm on the way down and at night. Its comfortable and the zip top is key for releasing heat on a tough climb. At night or on the slopes it's great as a base layer. Can't say enough about this thing... After 5 days in the wilderness, I come home and my wife says it smells clean. Pretty amazing!
