United Shield International introduces the Next Generation in shield technology, the USI C.E.R.T. Shield. The shield builds on our popular ERT shield design and functionality while taking its operational performance to the next generation of performance. The CERT shield enables the operator to function in unimpeded visual environment while maintaining 100% upper body and head protection. The viewport has the largest unimpeded viewing area of any shield on the market, providing a true 360 degree field of view. The complete clear, seamless upper section of the shield provides unparalleled situational awareness with no blind spots or viewing obstructions.
