The Iron Heart IHM-40-GRN A2 Deck Jacket is an improved, modern version of the old-school military original produced in an 11 oz. heavy-duty Whipcord twill that has been sulfur dyed in Olive Drab — which will patina over time — and is lined with a deep pile Wool flannel in the body and sleeves for warmth and luxurious comfort. This fall and winter weather, war-ready piece with new vintage appeal is an elevated reproduction based on the Naval Deck Jacket debuted in 1960 that was used by Navy deck and officer personnel for several decades. This Whipcord is fashioned after military-grade fabrics made from hearty cotton in a hard twisted yarn that's woven into a twill to create a corded ribbing effect while adding durability for a clean canvas that will evolve subtly with the heavy use this piece is intended to endure. This specialized A2 Deck Jacket is an improved military original — which will combat the cold with considered Iron Heart craftsmanship — that boasts a snapped flap patch chest pocket, flannel lined welted hand pockets, a buttoned and two-way zipper front with above military grade reproduction hardware, concealed ribbed storm cuffs, and adjustable waist cinches using military grade nylon strapping and buckles. Over-engineered to start, the 40-GRN A2 Deck Jacket will deliver a lifetime of durability in an unmistakable design packed with over-the-top details to strike a perfect balance between reproduction and evolved interpretation as a staple that's ready to roll into weather with battlefield bravado.

Iron Heart Outerwear sizing is graded in small increments. The 40-GRN runs on the large side of Iron Heart sizing, and for a standard fit consider taking the smaller of your Iron Heart size range or one size down. To accommodate heavy layering, or a roomy fit consider taking your common Iron Heart size.

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.
