Spring days in the mountains might feel like fall weather instead. If you're hitting up the trails during shoulder season or just have a day with in-between weather on tap, the lightweight Men’s Harkins Flannel Shirt offers all-day comfort and performance. The double-brushed flannel ensures you stay warm while the COOLMAX® EcoMade technology wicks away moisture to keep you dry. Built-in UPF 50 shields your body from dangerous UV rays. 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.
