Extreme Sleeve Reinforced Fabric.
ALPS Extreme Sleeve Fabric Reinforced has superior comfort provided by ALPS GripGel. The SFK has limited vertical stretch, and the elasticity of the fabric still allows the user excellent freedom of knee flexion. The extreme Sleeve also achieves secure suspension by sealing with the skin without restricting circulation, while the GripGel sticks to the patient's skin without causing shear forces. The grip will help prevent the sleeve from rolling down the patient's limb because of the nature of the GripGel.
