The Outdoor Research Melody Hoody is a versatile, mid-weight insulator ideal for any activity in cool to cold climates. An efficient cut and the wicking capacity of the fabric allows you to operate at high levels while the fabric continues to breathe. Best of all though is the plushness of the feel: made from 87% polyester with 13% Spandex. You'll have to feel it to believe it. A hoody you'll never want to take off.
