Thank you very much for viewing. The zipper is from EMAR, so I believe this product is from the 1970s. *I am not an expert, so I would appreciate it if the buyer could make their own judgment.* EMAR aluminum zippers were mainly used in American vintage wear from the **early to mid-1970s (early 70s)**, especially flight jackets and parkas. It has a wide body and a short length, so it looks great when worn with a hoodie underneath. The size is marked as 42, so I think it's about L to XL in actual size. It's filled with padding. Actual size (flat measurement): cm Marked size: 42 Length: 60 Width: 63 Shoulder width: 51 Sleeve length: 66 *It's old, so it shows signs of wear, but the zipper is in good condition and it can still be worn.* Recommended for those who like American casual, military, L2B, B-15, N2B, N3B, m65, m47, m51, G-1, A-2, y2k fashion, vintage, etc. HO-1709
