The sheer versatility of the Orvis Indigo Tech Woven Long-Sleeve Shirt makes it one of our favorite flannels from the Orvis lineup. It's crafted from a soft and very breathable mesh-lined material that's equally adept at relaxing in the backyard as it is working hard on the trail. Plus, the Indigo features a 30 UPF rating for added peace of mind after a long day in the sun.
