This is a padded jumper made with Gooseley material, which offers the same "warmth" and "lightness" as down. I bought it at a department store after seeing an advertisement that said it's washable in the washing machine and always clean! (Machine washable). The inner padding, [Gooseley], has excellent antibacterial and deodorizing properties, and it seems to have high heat retention and breathability. It's designed to release excess heat while maintaining a comfortable temperature. The hood is removable. It's incredibly light. I used it this winter in October, November, December, and January, but I'm selling it because I bought another outer garment. There's some dulling, but I'm selling it for outdoor play.
