This popular insulated jacket enters a new season of refinement with a larger stretch panel on the back for even more freedom of movement. Brushed inner fabric and low-profile, intelligent insulation throughout offers the warmth of a heavier coat without the weight or bulkiness, allowing you to focus less on your layers and more on your game. It's easy to slide this jacket on over any polo or midlayer and under a windproof or waterproof layer for additional protection from the elements. Of our insulated golf jackets for men, the Radiation Jacket offers all-around cozy warmth, allowing you to keep playing even when temperatures drop from cool to cold.
