One of the most advanced jackets on the market is Blauer's Supershell Jacket with Crosstech. This duty coat is built with Gore's antigen/pathogen resistant Crosstech fabric and is waterproof to boot. It's ANSI/ISEA Class II Certified with two-inch Scotchlite on the arms and torso to enhance night/low-light visibility. All of the seams are sealed; the material is a "stretch" fabric so the jacket doesn't restrict movement; the material is abrasion resistant; and the fabric is ASTM F903 certified to be resistant to the five most common crash-scene chemicals. Officers with the University of Pittsburgh Police Department say it's ideal when policing the parking lots and traffic details before and after sporting events.
