Moji fit (function inspired technology) is at the core of each Moji product. Our fit philosophy ensures that our products not only function well therapeutically, but also function well in your everyday life. Moji knee consists of a compression wrap and cold cell that articulate perfectly around the knee. This two piece system provides unparalleled convenience and mobility. Each Moji cold cell is soft and pliable right out of the freezer and remains cold for the recommended 20-minute icing protocol. Moji cold cell features dri-lex wicking material which eliminates wetness and protects the skin.
