This lightweight MA-1 bomber jacket is perfect for the coming season. It's thin and easy to throw on. The inside is mesh-lined, and the fabric is thin, making it ideal for chilly days during the rainy season and even in the fall. The size is listed as S, but it's not too small even for me, who usually wears a M! Length: 61cm Width: 50cm From shoulder to armpit: 23cm. Because it's raglan, it won't feel tight even with an inner layer that has fabric around the armpits. Light outerwear, water-repellent jacket, rainy season, mountain jacket, air conditioning protection, mountain parka
