I'll throw in a quickie breakdown to supplement the video but be sure to have a look for the in-depth explanation.
Knox is REV'IT!'s basic protection: CE Level 1 rated; constructed with a TPU outer and foam inner; extremely flexible, lightweight, with excellent durability.
ProLife is REV'IT!'s upgraded armor: CE Level 2 rated; made from elastomers, the armor contains micropores of trapped air which absorb and distribute the energy of an impact significantly better than entry-level armor; one streamlined piece of material.
SAS-TEC is REV'IT!'s premium armor: the highest CE rating available, basically CE Level 2+ rated; intelligent molecular level armor that is comfortable and malleable when contacted with body heat but instantly becomes rigid upon impact; the best available impact protection and dispersion of shock across a large surface area; offers maximum mobility and comfort.
