From blue-water pursuits to lake country expeditions and beyond, Simms staple Guide LS Shirt goes out of the way to enhance angling experiences. UPF50 nylon fabric is bomber, quick-drying, and wicks moisture with gusto, while the vented, mesh-lined back panel enhances overall airflow when the fishing heats up. Savvy storage stems from two pleated, fly box ready chest pockets paired with hidden, mesh backed, zippered chest options. While additional features include an internal license pocket and accessory loop; roll-up sleeves with button retainers; and a convenient sunglass cleaning chamois at hem. Traditional Fit comes standard.
