Defective item. Uniqlo Seamless Down Jacket. Women's size M, navy. I think it has a slimmer silhouette compared to the Ultra Light Down series. I wore it in rotation for one season, such as for commuting. There is almost no dirt, and it looks good at first glance, but... I didn't particularly notice it while wearing it, but there are areas where the bonding has come undone, such as the chest, sleeves, and back. ① The first line from the top ② Left sleeve front, except for the 2nd and 5th lines from the top ③ Right sleeve front, about half of the 1st line ④ Back, except for both ends of the 1st line ⑤ Back, the 1st and 2nd lines from the bottom The down itself is fluffy and still has volume, so please use it for when you don't mind getting it dirty, or for a quick cover-up when going to the convenience store or picking up family members. I would appreciate it if you could accept the condition of the seams.
