Much like the formation of golf balls on a driving range, this big & tall Callaway pullover jacket features speckles of unconnected dots make up each stripe, which rise and fall in an equalizing pattern from the chest to shoulders on the front. The inverse effect takes place on the back, mirroring the motif from side to side. We crafted the placket, sleeve cuffs and stripes with the same color to create a bursting tint. Callaway's Opti-Therm keeps you warm by creating a barrier between you and the cold weather, Opti-Dri moisture wicking technology pulls sweat away from your body so you can cool down in the heat, Opti-Stretch allows you to attack the green by providing your arms the freedom to produce a fluid swing and Opti-Shield gives your skin superior protection against the sun's UV rays.
