Used for only one season. Thick and fluffy on the inside. The outer material is windproof. A front pocket keeps the mother's hands warm while supporting the baby. There are also two large pockets inside where the baby's feet can be placed. It attaches to the shoulder straps of a baby carrier, making it easy to put on and take off. It can also be used as a swaddle when carrying the baby, or as a sheet or blanket for naps. It was very convenient! The color is a dark gray, close to black. The hood that can be put on the baby's head is removable. Please feel free to ask if you have any questions. :)
