Designed and engineered from the inside out, the Nike NFL Elite 51 uniform creates a system where the baselayer, padding, jersey and pant work in concert. Lightweight padding is also integrated directly into the crucial “hit zones” in the baselayer. New innovations include integrating Flywire technology into the neckline to reduce weight and provide lockdown fit over pads, increasing sleeve articulation for better range of motion, and integrating new four-way stretch fabrication to provide a streamlined shrink-wrap fit.
