The seemingly mild-mannered Brooks Heaterhog top holds a superpower within. Engineered with an innovative fiber, this remarkable top activates with moisture by not only pulling it away from the skin, but also generating heat back to the body. No magic here, it's inherent to the yarn so it won't wash out. Ideal for 40 to 65F.
