Vacuum volume management system that is slimmer, lighter, lower-clearance than Harmony P2 for lower limb amputees who want a precise socket fit for confident movement all day long.
  • Elevated vacuum reduces fluctuations in residual limb volume for precise fit throughout the day
  • 20% lighter than Harmony P2 for better user acceptance
  • Lower clearance (4.6 inches/117 mm) so more users can benefit
  • Smaller circumference for better cosmesis
  • Less complex 3-in-1 functional ring allows service in the field
  • Functional ring absorbs vertical shocks and allows for natural rotation
  • Suitable for weights of 88 - 275 lbs
  • Recommended for activity levels K2 - K4
