This is an MA-1 type gilet from andMe. As shown in the photos, it can be worn all year round depending on how you style it. I am selling it because I haven't had many opportunities to wear it since changing jobs. I wore it once outside after purchasing it, but there is a 3mm black spot on the back. It's not noticeable unless you look closely while wearing it, but please consider this a used item and only purchase if you understand that. The original price was 4,590 yen.
