A type of flexible boot sized to envelop an object mounted on a smaller shaft with one or both ends of the boot having an expandable opening. When used to protect an automotive type constant velocity joint, the boot will have one plain cylindrical end and one pleated end. The plain end of the boot mates to a housing of the CV joint, the opposite end mates to its input shaft. The shaft mating end of the boot is comprised of a circumference of radially arranged shaped pleats. During installation of the boot over the constant velocity joint, the pleated end of the boot may be spread apart and passed over the larger diameter of the joint housing. The pleats may then be closed inwardly to a nested condition where they are constrained and compacted to the shaft with a surrounding band clamp.
