The KAVU Echo Valley Jacket is a semi-fitted, full-zip flannel jacket with a brushed cotton twill shell, lined with high-pile sherpa through the body and collar. A straight pieced hem finishes the cut. What Our Gearhead(R) Experts Are Saying:"Pulling this jacket over a sweater is easy because the quilted sleeve lining slides over the layer underneath instead of grabbing it. Then I snug the cuffs down, and the sleeves stay put through a long, cold day outside."
