The four-season footmuff Bunker Explorer consists of two layers which can be used separately or together according to the weather. The outer layer made of taslon is wind-resistant and water-repellent. The interior is made of soft, heat regulating fleece and consists of a lined seat component and an insulating top which are attached by a zip fastener. The top part with a hood can be used separately as a body warmer. Both layers together provide warmth and protection from wind and weather in the winter. The foot part of the muff is detachable.
