Get ready for the wind with the Sun Mountain At Hybrid wind jacket. It features stretch panels and a no-sew quilting pattern with superlight 650 down fill. The quilting covers the upper body to prevent heat escape while the stretch panels provide maximum freedom of movement throughout each golf swing. The jacket also features vented knit panels that offer breathability to help prevent moisture build up. In addition, the DWR (durable water repellant) finish on the quilted panels offer water resistance. Design benefits include a stand collar for additional warmth, a hidden chest pocket for small accessories, and zippered pockets to keep your hand warm.
