When properly packed, it is nearly impossible to break a golf club in a Club Glove Stiff Arm Travel Cover. With nearly every touring professional carrying their clubs in a Club Glove travel bag 25 to 35 weeks a year, there's usually only 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 has 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.
