The classic N1 deck jacket was first produced for the US Navy in the early 1940s. Much copied since then, it has become a true style icon in its own right. The Iron Heart version remains pretty true to the original jackets on the basis that "if it ain't broke, don't fix it". The one major, but unseen, change we have made is to add an additional interlining to increase wind resistance. A truly warm and great-looking winter jacket. For this year's rendition, we have added the interlining to the collar and tweaked the pocket placement very slightly.

12oz Japanese Whipcord

Whipcord (also known as "Jungle Cloth"), is a strong worsted or cotton fabric made of hard-twisted yarns with a diagonal cord or rib and a steep-angled twill. The ribs of whipcord are usually pronounced and the weft (filling) yarn may be visible between the ribs on the right side. Whipcord is usually found in durable military, outdoor, and workwear clothing — typically pants and jackets. The tightness of the weave means the fabric has excellent wind proofing qualities and is performs better in wet conditions than most other cotton fabrics.

- 100% cotton

- Twill weave

- Woven with hard twisted yarns

Hard twisted yarns are spun with a high degree of twist, which makes them stiffer and stronger. This type of yarn is used to weave whipcord (“Jungle Cloth”) fabrics, increasing durability and resistance to abrasion.

- Reactive-dyed warp

In weaving, the weft is the term for the thread or yarn which is drawn through the warp yarns to create cloth. Warp is the lengthwise or longitudinal thread in a roll, while the weft is the transverse thread. A single thread of the weft, crossing the warp, is called a pick. Terms do vary (for instance, in North America, the weft is sometimes referred to as the fill or the filling yarn).

- Two-way main zipper with button fastening placket

In modern usage, the term placket often refers to the double layers of fabric that hold the buttons and buttonholes in a shirt. Plackets can also be found at the neckline of a shirt, the cuff of a sleeve, or at the waist of a skirt or pair of trousers. Plackets are almost always made of more than one layer of fabric, and often have interfacing in between the fabric layers. This is done to give support and strength to the placket fabric because the placket and the fasteners on it are often subjected to stress when the garment is worn. The two sides of the placket often overlap. This is done to protect the wearer from fasteners rubbing against their skin, and to hide underlying clothing or undergarments.
