Garment Measurements | Virtual Size Chart


The Iron Heart 30-IND N1 Deck Jacket is an improved, modern version of the old school military original produced in an 100% Cotton 11 oz. heavy duty Whipcord twill that has been Indigo dyed to evolve with wear, and is lined with an Alpaca Wool blend for warmth and luxurious comfort. This winter weather war-ready piece with new vintage appeal is an elevated reproduction based on the WWII Naval Jacket that debuted on the beachheads of Normandy, which remained in use by Naval deck and officer personnel for several decades. This Whipcord is fashioned after military-grade fabrics made from a hearty cotton in a hard twisted indigo dyed yarn that's woven into a twill to create a corded ribbing affect while adding durability for a clean canvas that will develop amazing character with the heavy use this piece is intended to endure. This specialized N1 Deck Jacket has an inter-lining to add wind and water resistance, and is lined with a long pile Alpaca wool blend in the body with a quilted satin sleeve lining to provide insulation, functionality, and a finished feel. This improved military original that will combat the winter cold with considered Iron Heart craftsmanship comes to fruition with alpaca lined snapped D-Patch front pockets, an interior snapped pocket, a buttoned and two-way zipper front with above military grade reproduction hardware, Permex snaps, buttoned throat and adjustable back waist and cuff tabs, concealed ribbed storm cuffs, and underarm eyelet vents. Over-engineered to start, this jacket 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 cold climate staple that's patina ready with battlefield bravado.
