The ALPS Extreme Sleeve with Reinforced Fabric (SFK) is a prosthetic suspension sleeve designed to provide secure vacuum or suction suspension while allowing freedom of movement.

• GripGel technology allows the sleeve to adhere gently to the skin without high shear forces to prevent bunching behind the knee and to minimize irritation.
• Controlled/Limited vertical stretch keeps the sleeve from sliding or rolling down while providing high horizontal elasticity for easy knee flexion.
• Uniform thickness of either 3 mm or 6 mm.
• Suitable for K1 to K4 activity levels.
• Sizing: Measured 10 cm above the knee center, spanning circumferences from 20 cm to 70 cm across multiple size tiers.
