The Extreme Warmer has a thermal tricot hood that can be raised to warm the ears and head. The jacket protects the most imperative muscles for heat production, as well as the neck, abdomen, and rib cage. The pleasantly soft, slightly flexible material does not limit mobility even on a sensitive dog. The abdominal section of the jacket has been dimensioned to cover the abdomen, which is sensitive to the cold, as well as possible. The effective 3M reflective pipings and the large reflective prints of the jacket improve the visibility of the dog in the dark. The renewed Extreme Warmer has had some details added to it that improves its utility from before: the adjustable length of the back, as well as the adjustable section in the hood have been inconspicuously placed on the inside of the jacket. Snap buttons have been added to the rear hem, with which the protective rear hem can be folded under the jacket. Also the jacket has been renewed with a softer, thicker type of wadding.
