Just like you, if the weather turns cold enough, your dog may need a little help staying warm. The puffy, insulated Ruff Wear Quinzee Jacket provides your four-legged friend with weather-resistant warmth for extreme cold so there's no need to hide inside all winter long. Reducing the loss of core body heat, the jacket utilizes lofty recycled synthetic insulation to ensure your dog's warmth. The 75D bluesign-approved polyester outer shell is abrasion- and snag-resistant and a 30D polyester lining provides next-to-skin comfort. Side release buckles make the jacket easy to put on and take off and integrated gussets at the chest use a blend of nylon/spandex to create stretch for a comfortable fit. Other features include a leash portal that enables the jacket to be worn over a harness, reflective trim for enhanced low light visibility, an attachment loop for Ruff Wear's The Beacon safety light (light sold separately). An integrated stuff sack lets you stow the jacket when not in use. The Ruff Wear Quinzee Jacket is available in your choice of color options and a wide range of sizes. See the Size Chart for recommendations and instructions on how to measure your dog for an appropriate fit.
