Popis: An improved backpack is provided including a frame, pack shell, shoulder straps and waist strap. Connecting the pack shell to the frame of the backpack are one or more vibration dampers. Preferably, the vibration damper includes a cylindrical housing formed with a vertically extending bore aligned with the housing's central axis. A bore is configured for telescopic receipt of the siderails of the backpack frame. Located within the bore of the vibration damper is a spring which attenuates movement between the vibration damper's housing and a collar which radially projects from a portion of the frame's siderails. Preferably, the vibration damper includes an adjustable air valve for selectively controlling air to enter into and out of the chamber formed within the center of the vibration damper.
