What makes up bunker gear/turnouts?

Bunker gear (also known as turnout gear, fire kit and incident gear) is the personal protective equipment (PPE) used by firefighters. The term can refer, depending on the context, to just the trousers, boots and jacket, or to the entire combination of protective clothing (which would also include gloves, helmet, and hood).

Trousers and jackets are made up of three layers: the thermal layer, the moisture layer, and the outer shell. 

Excluding the boots, helmet, gloves, etc. the cost of turnout gear usually runs at a minimum of $3,000.
