Description & Size guide

Heading outdoors for a long adventure in cold weather? Make sure your dog is protected as well as you are with the Hurtta Extreme Warmer Jacket. This innovative coat is lined with a special aluminium foil liner. Acting as a reflector for your dog’s own body heat, it invigorates blood flow and creates an extra warm layer to protect your intrepid canine companion in the most demanding weather conditions. It has a high hood to protect the neck and back of the head that can be extended to cover your dog’s ears and keep them warm as well.

Made from a waterproof fabric that is also breathable, it allows the air to circulate and prevents moisture being retained close to the body, increasing warmth. Reflective strips enhance safety after dark. Adjustable straps allow the jacket to fit more snugly.

If you and your dog enjoy extreme winter outdoor activities together, this jacket will make sure the two of you can be out there for as long as you need without fear that your dog will get too cold.

  • Extra warmth in demanding weather conditions
  • Protects major muscles in back, shoulders and chest
  • Waterproof and breathable
  • Adjustable straps for better fit

  2. The Neckline Measurement should be taken at the base of the neck, this being the widest point of the neck.
  3. The Chest measurement should be taken at the widest point of the chest from behind the front legs.
