What materials were bunker gear primarily made of in the past?

Bunker gear, historically used by firefighters, was primarily constructed from leather or canvas with a wool liner. This combination was chosen for several reasons. Leather and canvas provided a durable and relatively heat-resistant outer layer capable of withstanding harsh environments encountered during firefighting. The wool liner added insulation and comfort, helping to protect firefighters from both heat and moisture.

Over time, advancements in materials science led to the development of more modern protective gear, but the fundamental needs for durability, heat resistance, and protection from the elements drove the use of these traditional materials in earlier fire gear. This composition reflects the understanding of fire dynamics and the necessary protective measures that firefighters had to consider in their equipment.
