Sixs Sas-Tec knee protector

SAS-TEC is a material that combines chemistry with cutting-edge technology to create a high-performance shock-absorbing system. In its normal state, SAS-TEC protection is flexible; with body heat, the material warms up and adapts perfectly to the body's anatomy. On impact, the kinetic force is transmitted to the atoms, which weld together, stiffening the entire structure to absorb the shock and protect the body. For maintenance, handle with care and wash by hand in cold water.
