Rubber Insulation Plastic Dome Caps are another design that combines the advantages of rubber and plastic. Rubber itself has good thermal insulation and elasticity, while plastic provides the necessary strength and portability. This type of hat usually uses rubber as the outer material, and a plastic frame or lining inside.

The thermal insulation performance of rubber mainly comes from its lower thermal conductivity, which allows it to block the transfer of heat to a certain extent. At the same time, the elasticity of rubber also makes this hat fit more closely to the head when worn, thereby reducing heat loss. The use of plastic skeleton or lining ensures the overall structural stability and lightweight of the hat.

Overall, the rubber Insulation Plastic Dome Caps have good performance in terms of thermal insulation and wearing comfort. Especially suitable for use in cold environments, it can keep warm without adding extra burden due to heavy materials.
