A little cool weather won't stop you from hitting the golf course when you've got this Callaway Weather Series™ golf top in your wardrobe. Made from thermal fleece fabric, the midweight men's base layer provides the warmth you need on chilly days. Opti-Dri™ moisture-wicking technology moves perspiration away from your skin to keep you feeling dry. A 1/4 zip collar lets you adjust the opening for easy on and off as the weather changes. With added stretch in the fabric, you can swing without ever feeling constricted.
