Fleece dog clothes YKK zipper Dark blue Size: 3L The outside is fleece and has small pills all over, as shown in the fourth photo. The inside is velour-like, making it less likely to attract hair and feels nice. There is a supplementary cloth attached to the zipper to prevent hair from getting caught. See photo 3. I've worn it many times, but it's well-sewn and I think it can still be used. Please purchase if you understand that this item has been stored at home.
