This is a Patagonia reversible vest. It's a thin and lightweight outer layer. It's a vest that's easy for young children to put on and take off, making it convenient for adjusting their body temperature. There are no tags because it's a reversible item. I believe it's around a 2T or 3T size based on Patagonia's official size chart. I've included images with measurements taken with the vest laid flat, so please be sure to check them. There are no noticeable scratches or stains, but please understand that this is a used item and has been stored and inspected by a private individual. Thank you for looking. D
