Pretty Paw's Tungsten Noir snow suit is named after the mineral Tungsten that was discovered by Juan José and Fausto Elhuyar, Spanish chemists and brothers, in 1783 by sampling wolframite. The Expedition Snow Suit is designed for full coverage to keep your pet dry and warm during the cold winter season starting with a hooded collar that can extend to the top of the head. By simply pulling the drawstring elastic cord, then locking it into place with the fastener, this added feature protects your pet's head and face. The composition is created to fit any shape or size breed with its adjustable drawstring cord that fastens at the center waistline for a more customized and comfortable fit. The snowsuit extends to all four legs with an added cozy ribbing cuffed around your pet's ankles to keep the snow out, but preserve the heat in. The composition is made of durable, water-resistant outer material and inside lining with a pillowy fill for an added feeling of warmth and comfort during those long, chilly outdoor walks.
