Product details:

Carrying a heavy pack on a cold day used to end in one of two miserable ways. One, you wear a jacket and end up with a hot, sweaty back or two, you wear a base layer and freeze the whole time. The Ovis Merino Sweater is your solution, with a revolutionary combination of 260-gram Merino wool in the arms and back, and synthetic insulation in the chest and sides. It'll make you one happy hunter, not to mention warm and dry. Of course, you still have to carry that pack.
