Size is XL, but Scotch and soda runs on the smaller size, so a size L is probably more comparable. If I were to rate this as a blazer size, it would be a 42. Fabric and materials are posted on label pictured. Great condition, super soft and warm. Loved wearing this with a hoodie and jeans, or some days wearing it with a long sleeve tshirt and sweat pants. Super versatile, can be dressed up or down depending on your style. Great details and 100% lined. Features a center vent in the back. Pockets can be worn tucked inside or out (like in the pictures) depending on what you prefer. Measurements: Shoulder to shoulder: 18.5” back and front Length: ~35-36” Opening at bottom: 23” Mid section: 21” Sleeve shoulder to end: 24.5” (with room to extend 1”) Sleeve armpit to end: 17” (again with room to extend 1”)
