This is an Alpha L-2B air crew flight jacket. It has three patches. It's thinner than an MA-1 and easy to pair with a sweatshirt hoodie. I bought it because I liked it, but I haven't worn it much, and it's been sitting in my closet for 2 or 3 years. There are no noticeable stains or damage. Shoulder width: 45cm Sleeve length: 70cm Body width: 59cm (underarm) Length: 70cm (collar to hem)
