Black Matt with Black Trim

Our Black Polypropylene Mats are filled with Non Absorbent Inners for extra warmth. Here are some facts about Polypropylene. In New Zealand, in the US military, and elsewhere, polypropylene, or 'polypro' (New Zealand 'polyprops'), has been used for the fabrication of cold-weather base layers, such as long-sleeve shirts or long underwear. Polypropylene is also used in warm-weather gear such as some Under Armour clothing, which can easily transport sweat away from the skin.
