Made of double-sided fleece material, it's easy to put on and take off with Velcro. It has a leash hole. According to the purchase memo, the chest measurement is 50-58cm and the length is 42cm. I bought this because I thought it would be okay since my dog doesn't like wearing clothes, but it was too big. I only put it on once. After that, it was stored away. The Velcro is strong. I would appreciate it if someone who understands this would purchase it. Thank you very much.
