Introducing the First Lite Men's Rugged Wool Field Long Sleeve Shirt. Merino wool has long been a hunter's best friend for its thermal properties when wet and natural anti-odor qualities. Perhaps the only drawback to Merino knits is that, like most other knit fabrics, they are prone to snagging, picking, and pilling. Through years of development, First Lite has built a robust double-knit wool fabric that is both durable on the exterior and soft on the interior, bridging the gap between baselayer and outerwear. This new fabrication has been fittingly dubbed Rugged Wool and its franchise of products is designed to take you from the house to the field and everywhere in between.
