When properly packed, it is nearly impossible to break a golf club in a Club Glove. With over 500 touring professionals 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 ads vertical strength to what is already the most protective soft sided bag in the world.
