The Extreme Warmer has taken the requirements of thermal jackets for dogs to a new level, both for dog walkers and for those involved with dog sports. The foil pattern which reflects the dog’s own body heat back to the dog, as well as the water and windproof surface material make the jacket especially warm. In addition to the high collar, the jacket has a thermal tricot hood which can be used 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 the mobility even on a sensitive dog and the jacket also features 3M reflective piping and large reflective prints at the front and rear hem of the jacket to improve the visibility of the dog in the dark. The renewed version of the 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 also been added to the rear hem and the thermal ability of the jacket has been renewed with a softer, thicker type of wadding. High, foil lined hood. 3M reflective piping. Hind leg straps. Adjustable back, chest and neck.
