Kick back after a long day on the mountain with the lightweight warmth of the Women's Lakota Flannel Long-Sleeve Shirt. COOLMAX® EcoMade technology dries twice as fast as cotton so you stay comfortable, while the sun-blocking UPF 20 protects you from the sun's harmful UV rays. Split side seams and a longer tunic length make it easy to pair with leggings. Chambray piecing at the chest pocket and back body add a stylish touch. Reduce your environmental impact with the Marmot UpCycle® fabric, which is made from post-consumer plastic bottles, which are recycled into quick-drying polyester fabric then blended with cotton.
