When properly packed, it is nearly impossible to break a golf club in a Club Glove. With nearly every touring professional carrying their clubs in a Club Glove travel bag 25 to 35 weeks a year, we experience a total of one or two incidents of club breakage. This generally happens when the bag is dropped directly on the club heads from a height of six feet or more. The Stiff Arm® is an adjustable crutch that is designed to prevent this from happening. It adds vertical strength to what is already the most durable soft sided bag in the world.
