M65 Field Jacket - Olive Drab

I bought this jacket (made by Propper) years back but never wore it due to the sizing. It's a medium regular size but fits way too big around my body (I'm slim). I'm 5'11" and weigh 155lb. The shoulder fit and arm length are good but it feels like a tent around my torso, even with the drawstrings at the waist and bottom cinched up. If you have more of a stocky build or you're expecting to wear a lot of bulky clothing underneath, it would be just fine. It's a shame because it's a high quality jacket and I love the features and I hate to sell it but if it don't fit, it don't fit. Would be great for camping, working outdoors, hunting or wearing casually. Here's the description from Propper: AUTHENTIC DESIGN – This M65 coat is built from military specifications down to its authentic NYCO sateen fabric, unlike many imitators using lower quality polyester blend fabrics. It offers a layering design that allows for use in any element or for casual wear. FUNCTIONALITY – Versatile coat with a storm flap and Vislon zipper, fully lined shell with a button-in removable quilted liner, and a packable hood hidden in the collar. It is the perfect fit for any weather or storm and will keep you warm and dry. COMFORTABLE FIT – With a loose fit across the shoulders, you have full mobility and range of motion while wearing the coat. There is an adjustable drawstring at the waist and bottom to accommodate any fit. STORAGE – There are 4 snap closure pockets conveniently located on the front of the coat for easy access and plenty of storage for your belongings. MATERIAL & CARE – treated with a durable water repellent to resist dirt and moisture. For fabric care, wash with a mild detergent in cold water and tumble dry on a low, warm, and gentle cycle.
