Drawing inspiration from classic 1940s U.S. Navy deck jackets, this lighter version of the N-1 replaces the traditional thick alpaca wool insulation and quilted sleeves with a significantly lighter, weather-resistant lining made of Japanese Ventile cotton. This gives the jacket a slimmer silhouette, enhances breathability, and provides added protection against wind and rain.
For the autumn/winter 2026 season, Iron Heart uses a reactive-dyed fabric, the same material found in the wool-lined versions. The jacket is finished with a corduroy-lined collar that contrasts with the whipcord outer shell. The result is a jacket that blends classic N-1 styling with an ideal weight for transitional weather.
