We updated the Extreme Warmer ECO, one of our most popular, earth-friendly winter jackets, for even greater performance and wearability, empowering you and your furry friend to conquer winter’s chilliest days. The Extreme Warmer ECO caters to all dogs, especially those active in hobby and racing sports, seniors and other cold-sensitive pups, and, of course, our short-haired and hairless friends who need that extra dose of warmth and care. The Extreme Warmer ECO offers effortless dressing and undressing, making it perfect for before, after, and in between sports performances, and for daily winter strolls and jogs.
