The warmest jacket in our lineup, the N-3B was originally issued in the 1950s as the answer to ultra-cold, windy environments some U.S. Flight Crews faced. Also known as the "Snorkel" parka, because the hood zips past the nose, leaving only the eyes exposed (much like how a snorkel would).

The N-3B features four external pockets that close with snaps - two handwarmer pockets on the chest, and two flap pockets down at the waist. An internal drawstring allows you to adjust the fit through the waist, and 100% wool knit storm cuffs keep your wrists secure.

Designed to resist cold temperatures, the N-3B is sewn up and lined with high-quality nylon, with a wool pile interlining sandwiched between the two. The hood of the N-3B is lined with 100% wool and trimmed with coyote fur. The jacket weights up to 2.5-3kg. The cold protection level can be comparable to 350g filling weight of high filling power down coat.
