What fur is the warmest?

Thermal properties of fur
The main purpose of fur products is to keep you warm during the cold season. Thermal insulation properties of a fur coat or hat depend on the height, density and elasticity of the hair cover. If this can be determined by visual inspection, the next parameter - the stability of the air layer, without special equipment can not be calculated. Fortunately, this data for each fur coat is defined and freely available. Here is a rating of the warmest furs (in descending order): Beaver, Arctic fox; deer; silver fox; sheared sheepskin; sable; rabbit.
