When venturing outside on a cold morning - for a snowshoe adventure or a simple java mission - there are two things you would never fail to do for yourself: 1. Layer to protect against the elements 2. Take your four-legged friend best friend. Shouldn't said friend be afforded the same protection against the cold? All-weather protective gear reduces the loss of core body heat (and also protects from brush and burrs). The Ruffwear K-9 Overcoat features a recycled fleece insulating liner enclosed in a durable, recycled polyester shell. Approximately 95 precent of the K-9 Overcoat is made from recycled materials.
