Abstract: A back pack for in-line skates includes a relatively large central compartment having a lateral shape in section somewhat resembling that of an in-line skate or ice skate with its integral boot. The sides of the central compartment include fixed loops and openable adjustable straps for removably securing one of a pair of skates to each side. The back of the central compartment includes a removable and adjustable helmet retaining net, providing for the removable retention of an in-line skating helmet or the like externally on the back of the pack. Additional smaller bottom, lower rear, and upper storage compartments may be removably or permanently attached to the central compartment. The pack includes adjustable padded shoulder strap loops extending from the upper front to the lower front of the central compartment, and a padded hip support belt extending from one side to the other across the front of the lower compartment.
