Garment Measurements | Virtual Size Chart


The Iron Heart IHM-38-OLV M-51 Type Field Coat is an improved, modern version of the old school military original produced in a 5 oz. heavy duty, lightweight, and water-resistant 70% Cotton and 30% Nylon cloth, paired with a removable quilted ripstop nylon liner to provide heritage style with four-season utility. This war-ready piece with new vintage appeal is an elevated reproduction based on the harsh weather coats introduced in 1951 for the Korean War, which remained in use by infantry and officer personnel for decades. This 70/30 cloth is fashioned after military-grade fabrics made from hearty cotton and high quality nylon milled into a lightweight fabric that is durable as a shell to be worn on its own, or paired with the button-in full body and sleeve liner for insulation in colder climates. This specialized M-51 Field Coat utilizes an improved modern fit that keeps a proportional silhouette while allowing for increased mobility and layering versatility with darted back shoulders, set-in sleeves, and articulated elbows. Furthering a tribute to the military original through enhancements and considered Iron Heart craftsmanship, this coat comes with a concealed Permex snapped storm flap and above military grade two-way YKK zipped front, concealed snap storm flap welted hand pockets, button tab adjustable cuffs, and a signature split fishtail center vent along with a drawcord adjustable hood, waist, and hem, finished with interior patch pockets on the liner. Over-engineered to start, the 38-OLV Field Coat will deliver a lifetime of durability in an unmistakable design that's packed with over-the-top details to strike a perfected balance between reproduction and evolved interpretation for a fall through spring staple with battlefield bravado.

Iron Heart Outerwear sizing is graded in small increments, and the 38-OLV generally runs true to Iron Heart sizing. To accommodate layering, consider going one size up from your common Iron Heart size, or the larger size of your range. For a tailored fit or to wear with just a base layer, consider going with your normal size or the smaller of your Iron Heart size range.

Our Method of measuring is different than Iron Heart. We recommend consulting our Sizing Guide and using our Virtual Size Chart to reference our Method when purchasing.
