Slagbjørn Jr. Thermo brings style and function to the coldest winter days. These boots are constructed from durable natural rubber which offers waterproofing and flexibility. Slagbjørn Jr. Thermo is warm lined with a quick-drying polyester fleece, and a temperature-regulating insole that provides extra insulation and warmth. The shaft can be pulled shut to keep snow out and warmth in. Underneath, the non-marking high traction sole tackles slippery winter conditions with ease.
