【Please read the profile before purchasing】 The zipper seems to open and close relatively smoothly both up and down. There are small pills overall, but I've removed them as much as possible with a pill remover. My personal impression is that: It seemed to be light, warm, and easy to move in. The zipper goes all the way up, so I think it kept out cold air from the neck. It was useful in the fall and winter. This item was used by a child and has been inspected by an amateur.
