Vibration damping devices for skis and other applications, the damping devices comprising a Cantilevered Impact/Friction Damper (CIFD) and an Improved Constrained Layer Damper (ICLD), the CIFD including a frame affixed to a portion of the vibrating body and having a cantilevered tubular member adapted for oscillation relative to the frame such that when subject to high amplitude vibration, a free end of the tubular member having a mass alternately strikes a pair of confronting stops, the tubular member having a plurality of particles disposed therein which dissipate low amplitude vibration through inter-particle friction; the ICLD comprising a spacer member having at least one layer of viscoelastic material and at least one constraining layer attached thereto, the spacer member having a plurality of slots spaced along the longitudinal extent thereof to reduce the bending stiffness of the spacer member without diminishing the damping effect.
