The Real McCoy's

N-1 Deck Jacket


USD 759.38 (Tax Free)


The N-1 Deck Jacket has become a staple of the modern man’s winter wardrobe. But N-1 refers not just to a jacket, but to an integrated clothing system designed for protection in cold climates and foul weather.

The U.S Navy developed three “N” systems. In addition to the cold climate N-1, the N-2 system was designed for rainy conditions and the N-3 system for tropical conditions. Despite these climate divisions, old photographs indicate sailors rarely used these systems according to regulations, opting instead to mix and match to suit their layering need and preferences.

Originally designed in the early 1940’s. The material for the outer shell is durable grosgrain cotton and the lining is a double-faced alpaca. The label 'NXss' shows a jacket was produced before 1944. After 1944, the label changes to 'NXsx' and the colour of the 'jungle cloth' also changes to a khaki colour.

The jacket also features 1940's bell-shaped Talon zippers and a Storm Flap Cover. An iconic jacket produced to the highest spec by The Real McCoys.

The Real McCoy's

The Real McCoy's is a brand like no other. To many the outdated features of vintage clothing have little significance in today's modern society, but this is exactly what influences the brand. American fashion of the 1940's and 1950's is a source of great inspiration; a young country unburdened by the restrictions of traditional customs, one that’s uninhibited, rational and innovative. 

However, this ideology is not enough. To make extraordinary clothing with vintage details and twists requires the sensitive minds and outstanding work of craftsmen in Japan. They are highly skilled at manufacturing materials using the same methods and machinery from the past. Whilst they endeavour to create the very best reproduction, they also seek to make it even better than the original.
