The GBZ hat is the same hat worn by the GreenBroz team at various events and trade shows. The logo is made of rubber/foam and gives this lid a futuristic, modern look. The hat itself is made of quality material with an “airy” mesh at the back of the hat to help keep your head cool on those hot days. Stay cool and look cool with this OFFICIAL GreenBroz Inc hat. Get yours while supplies last.
