Callaway have done everything they can for this year\'s Autumn/Winter collection so that you can look your best, play your best and still keep warm throughout even the coldest days on the course. Once again Callaway have implemented Swing-Tech to make sure you can have no restrictions when you are on the course. Swing-Tech allows the jacket to stretch more and in areas that benefit from added stretch so you have complete freedom of movement in the garment, meaning every shot can be played just how you want it to.
