【SIVI Artificial Feather Down】 Size: M Color: Beige While it's in relatively good condition as it was outgrown before being worn much, please understand that this is a used item that a dog has worn. This is a 2024 Fall/Winter product. I couldn't find the size chart on the website, so I will measure and provide the flat measurements later. For reference: My female Whippet wore this when she weighed 8-9kg. Below is the product description from the official website: A down vest that protects your dog from wind and cold with its excellent heat retention artificial feathers.
