The Icelandic horse grows a thick winter coat that can resemble a fur coat

The Icelandic horse is exceptionally well adapted to the Icelandic winter, and this is most visible in the thick winter coat it develops during the coldest months of the year.

As autumn approaches, the coat begins to thicken, gradually turning into a deep, fluffy layer that can sometimes look almost like a fur coat.

This coat has two layers: a soft, insulating undercoat that retains heat, and a longer, water‑repellent outer coat that protects the horse from snow, rain, and wind. This natural insulation allows the Icelandic horse to stand outside in severe cold without losing body heat, even in storms or frost.

​

The coat is so effective that snow can rest on the horse’s back without melting — a sign that warmth is not escaping from the body.

This remarkable adaptation is one of the reasons the Icelandic horse has survived and thrived in a harsh environment for more than a thousand years.
