Purchased in February of this year. Tried it on my dog indoors once, but it was too big, so I'm selling it. It's like new because it's never been worn outside! It's recommended to wear it during the cold hours of the day! You can still wear it. The back has a zipper, making it easy to put on, and it has a leash hook, so you can attach a leash directly! Navy blue is also available in a different color! *It may be removed as it is also listed on other sites. Size: M Belly: 35 cm Neck: 24 cm Back length: 30 cm
