I tried it on at home. The tags are still attached. Please check the product page on MUJI's website for the product size. No claims and no returns, please. I will fold it up small (compress it) for shipping. Uses 750 fill power down with a large amount of loft. Anti-static thread is used in the lining to prevent static electricity. 【Material】 This down jacket uses a nylon material with a matte appearance, giving it a less casual impression. The outer fabric is water-repellent, repelling light rain. 【Design】 Upgraded to a stitchless three-layer construction for a clean look. While maintaining its function as an inner down jacket, it's also designed to look good as an outer layer. It's also pocketable, making it convenient to carry. 【Specifications】 Fabric Thickness: Thin Fit: Regular Lining: Yes Material...Nylon
