Issued in 1958 by the U.S. Air Force, the N-3B commonly known as the "Snorkel Parka" due to its small opening when the hood is fully zipped. The parka was designed to withstand extremely cold environments and has undergone minor changes ever since. The Real McCoy's have faithfully reproduced this singled breasted 4 pocket classic using a beautiful 66 Nylon fabric with wool pile interlining. The Hood is lined with a soft mouton and then finished with coyote fur trimming.

Nylon 66 was invented by DuPont Co. Nylon 66 is more flame resistant and durable compared to other nylon fibers. The Real McCoy’s have studied the original Mil-Spec formula to replicate its yarn, density and weave, a full original of the brand.
