This is a high-performance all-season romper. It's a rash guard for UV protection, etc. I recently purchased this, but I made a mistake with the size, so I'm selling it. Recommended for owners of BS-sized dogs. It looks cool. Opened, but the tag is included, although it has been cut off. It's new. - Color: Gray - Material: 78% Polyester, 22% Polyurethane - Size: BS, Back Length 29cm, Chest 48-53cm, Neck 33-37cm The fabric has stretch, but it's firm, so it's recommended to choose the size that fits your dog's body. Also, if your dog will be in water like a pool, the fabric seems to loosen slightly, so it's recommended to choose a size smaller. This is advice from the shop staff... No comments, immediate purchase OK. Thank you. Type: Romper
