Size: S Khaki Quilting with a smooth, cotton feel. Casual design with a tag on the back as an accent. The inside is warm with fluffy boa fleece! Since it is not stretchy, we recommend a size with some余裕 (yutori - room/give). *We do not recommend using the D-ring on the back to attach a leash for walks, as it may be unsafe due to concerns about strength. Please consider it as a decorative element.
