It is new and unused, but has been pre-washed once. Please purchase if you understand that it has been stored at home. The following is quoted from the official website. ＜Key Feature ①: You can walk and play while wearing it because it has feet＞ Around the ages of 2 to 5, children are always excited to walk! We designed it so that they can safely wear it even when they get up from bed or play after waking up. Because your child can walk alone while wearing it, you don't need to take off the sleep sack to take them to the toilet at night! You can go to the toilet with your child while they are still wearing it. Even on days when it's a little troublesome to change your child's clothes after they wake up, with a footed sleep sack, you can let them play as they are. ＜Key Feature ②: Your child can sleep in their favorite position＞ Unlike swaddle sleep sacks and sleep sacks, the design allows both hands and feet to move freely, making it perfect for children who have grown. Because it is designed to move freely, your child can find a comfortable position on their own! ＜Key Feature ③: A sleep sack that is neither too hot nor too cold＞ The footed sleep sack is designed to wrap the entire body, including the ankles, so it can keep the whole body warm while releasing heat from the feet. Therefore, it is designed to prevent heat from building up and to easily adjust the temperature. ＜Thoughtful Design ①: Gentle design that doesn't touch the skin with the zipper＞ The zipper at the neck has a cover made of soft material. We designed it to be gentle so that the cold metal part does not touch your child's skin. We also paid attention to the gentleness of the zipper on the main body for your child's skin. By attaching a piece of cloth under the zipper, the zipper does not touch your child's skin at all. ＜Thoughtful Design ②: Easy to put on and take off with one zipper＞ The footed sleep sack is designed to be put on and taken off with one zipper, so there is no need to fasten many buttons. Just put your child in the sleep sack and then zip it up! It's complete with just one zipper when putting it on and taking it off, so it's perfect for children who want to move around a lot at this age.
