Keep Warm on Golf Course – How to Golf When Cold
Golfers hate to miss a day of golf, but sometimes the weather isn’t very cooperative. If there’s frost on the grass, the game is delayed but not canceled. Heading out for an early tee time sometimes means chill conditions especially if it’s windy as well.
The problem is keeping warm enough to play well. Cold hands affect the feel for the club, while too many warm clothes make it hard to get the proper turn needed for a golf swing.
