Callaway have done everything they can for this year's Autumn/ Winter collection so that you can look your best, play your best & 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 & 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.
