Humans' body hair is not very dense either. Thus, hair is a characteristic of mammals, but dense hair covering the entire body is not.
Insulating body hair typically has a dense structure that traps air, providing effective thermal insulation to maintain body temperature. It is often longer, coarser, and may be layered to enhance warmth. Additionally, insulating hair can be water-repellent, helping to keep the skin dry and further enhancing heat retention. This type of hair is commonly found in mammals living in colder climates.
