I bought this for my child to use at nursery school when they were in their fourth and fifth years. It was quite high-functioning and easy to use. It also has a pocket for the toilet, making it perfect for young children. It didn't soak through, and it seemed warm. It has a size adjustment function, so my child was able to wear it for two years, from 95cm to 105cm. My daughter, who is very particular about cleanliness, wore it, so there isn't any noticeable dirt, but there is some pilling on the inside due to friction. Please understand that it will be shipped compressed.
