Alpha Industries N-3B Parka

The product shown is an Alpha Industries N-3B parka, also known as a 'snorkel parka.' Originally designed for the United States military in the early 1950s for air crews stationed in extremely cold climates, the N-3B became a staple of civilian winter wear due to its durability and insulation.

Key identifying features visible in the image include the characteristic high-contrast emergency orange lining, designed to help stranded personnel be spotted from the air, and the signature zippered utility pocket on the left sleeve (often referred to as the MA-1 pocket). Alpha Industries began as a military contractor in Knoxville, Tennessee, in 1959. Over decades, it successfully transitioned from government contracts to a global lifestyle brand. While the brand maintains deep roots in American military history, most of its commercial production is currently based in Asia, particularly China.
