This sleeve provides the same suspension and comfort the Silipos BK sleeve is known for, but with added durability for more active lifestyles. It has a reinforced fabric liner that protects the sleeve from the wear of the brim of the prosthesis. Additionally, the HD-BK Heavy Duty Reinforced Suspension Sleeve contains the same Silipos medical grade mineral oil as our other products to provide maximum skin conditioning benefits. It also provides excellent suction while offering protection from shear and abrasive forces.
