This Callaway Weather Series™ golf sweater is crafted from soft, midweight fleece with a waffle knit for comfort and casual style. It's enhanced with stretch, letting you swing smoothly and without restriction. Thermal fabric combined with Opti-Dri™ moisture-wicking technology creates a barrier between you and the cold and keeps you dry on the back nine. The golf pullover features a 1/4 zip mock collar that keeps the wind off your neck, and allows for easy removal when the sun breaks through.
