The Challenge

A functioning thermoregulation at the joints, places the highest demands on the material and the functions. Joints are exposed and therefore cool faster compared to the rest body, added on, they also require maximum freedom of movement.

The Solution

The Expansion Ribs® that form the elbow cushion work similarly to the knee area, but are fine. The knitted fabric folds apart based on the accordion principle, ensuring that winter cold doesn’t cool down the elbows. Even when sharply bent, the insulating effect is maintained through warm air stored in the interior. The flexibility of the Expansion Ribs® and the elasticity of the yarn allow a frictionless freedom of movement. Even sports with continuous arm movement, such as cross-country, produce no symptoms of musculature exhaustion from the movement of the Expansion Ribs®.
