Oh em gee, better than a foil hat!
This hoodie top is specially designed to conceal your identity from closed-circuit television. It’s a project by artist Adam Harvey, and part of a line of similar pieces of clothing he’s created. It’s made of metallic reflective fabric not unlike the protective material used in some layers of firemen’s uniforms. The idea is that the material smears out or otherwise conceals your body’s thermal output and that can confuse overhead surveillance cameras—like those you sometimes see used on late-night cops reality shows.
