Discover new trails to blaze with the heathered Men’s Jasper Midweight Flannel. This shirt is double-brushed for all-day comfort, wherever your adventures take you. Heading into an open field before you pick up the trail? UPF 50-rated fabric will block the sun's harmful ultraviolet rays while moisture-wicking COOLMAX® EcoMade technology keeps you dry. Reduce your environmental impact with Marmot UpCycle® fabric, which is made from post-consumer plastic bottles that are recycled into quick-drying polyester fabric then blended with cotton.
