When you need additional warmth in the cool weather, add the Second Layer Thermal pullover. It provides comfort and performance on or off the golf course. Comfort features include 4-way stretch fabric that is designed to move with your body and lightweight fabric that will not weigh you down. Performance features include a stand collar to help keep in the warmth and moisture wicking capabilities so your skin remains dry when sweating occurs. The adjustable ¼ zip placket can be zipped for complete coverage or unzipped to show off a Sun Mountain undergarment.
