Vessl's KinnTM Automatic Volume Management System automatically adjusts to the natural changes in your limb throughout the day. Whether you're sitting, standing, or moving, the KinnTM system maintains even pressure for a secure, comfortable fit without the need for constant manual adjustments.
More mobility through the day without stopping to add or remove socks.
Even pressure reduces hot spots and skin irritation, minimizing strain with every step.
At work, in the gym, or at rest — a fully mechanical system built to support your lifestyle without compromise.
As your limb size fluctuates through the day, traditional sockets become loose or too tight — leading to discomfort, skin irritation, and shorter wear time. Many amputees manage this by adding and removing prosthetic socks, over and over. Kinn™ replaces that routine with a socket that takes up volume change on its own, holding the tension you and your prosthetist chose.
