Thank you for viewing. This item was purchased yesterday at Pet Paradise. After trying it on, the size didn't fit my dog, so I'm offering it to someone who can use it. It's only been tried on, but since a dog has worn it, please refrain from purchasing if you are at all concerned. The following is from the website: Features [Peti Heat] This pet wear excels in heat generation and heat retention. The fibers absorb moisture from the air and generate heat when it evaporates. The soft woven fabric is gentle to the touch, and it traps the warm air created by the dog's body temperature, preventing it from escaping. [Thermolite] Thermolite (R) core technology keeps you warm. In addition to its heat retention properties, it also has stretchability and is designed to dry faster than conventional products.
