The grill where i work in the summer is an order of magnitude hotter than any other grill i've worked at. Stuck a thermometer on the counter on the other side of the aisle and it reached 140F. With this kind of heat, is well ventilated clothing still the best option? Should i be wearing thicker cotton jackets to try to protect from the radiant heat? Is there other options? Are there non shiny versions of like metal working clothing or clothing to work near volcanoes? Or like firefighter jackets?
