Length 56cm, Width 54cm It's not as thin as Uniqlo's light down, but it's not super thick either. It's a medium thickness. Depending on the region, it might be questionable whether it can handle the dead of winter... but this isn't an extremely cold area, and I tend to get hot easily, so it was fine for me. There are no major noticeable flaws, and it's in good condition. I think it can still be used for a long time. Please understand that there are individual differences in how things are perceived, so this is for those who understand that this is a used item. I have a cat. I'm lowering the price as I see fit, so I can't accept price negotiations.
