This is a Converse down vest. The filling is 50% down and 50% feathers. It's fluffy with no clumping and in beautiful condition. It's perfect to wear over a long-sleeved T-shirt. The zipper is YKK. It's labeled 150-160, but it feels a bit small, so I think it's suitable for children aged 140-150. I will compress it slightly for shipping. Thank you.
