Purchased in January 2024 and tried on at home. The size didn't fit, so it was stored away, but I found a slight stain on the collar (see image 4). This is a used item, so please consider this before purchasing. The outer material is a smooth quilted fabric, and the lining is fleece, which is fluffy, soft, and gentle on the skin, providing a comfortable fit. It has snap buttons at the back, making it easy to put on and take off! Size: 2XL Measurements (laid flat): Width: Approximately 27cm Length: Approximately 40cm Neck circumference: Approximately 36cm Material: Polyester, Polyethylene Terephthalate, Cotton Color: Blue #DogClothes #DownVest #ColdProtection
