This is a CRYSTAL BALL down jacket. It has never been used for everyday walks. I bought it for going out. Although it's over 10 years old, it's thick and the sewing is very well done, so there are no signs of wear or fraying. The size is 3S. I used to put it on my 1.8 kg Chihuahua. I think it would fit up to about 2.5 kg. The surface is made of a corduroy-like fabric. If you want to dress up your dog, please consider it.
