It has down filling, although I don't know if it's 100%, it is quite thin and heats up a lot considering the thickness, it's for not so cold days. I'm 1.84m tall, weigh 90kg, and the 3XL fits me comfortably, but the sleeves are short. If you could sell a version with the sleeves about 10cm longer, it would be great.
Good quality, thank you, boss
