Heavy-Weight: Protection against sub-freezing weather conditions. The Altitude is an N-3B inspired parka with an Oxford nylon shell and polyester twill padding and lining. The first N-3B jackets were produced in the 1950s for air crews who were assigned to transport troops in extremely cold climates.
This version of the warm parka comes with a soft faux mouton lined hood, inset knit cuffs and a removable faux fur strip around the hood to protect you against the elements. Other features include drawstring waist, right arm shoulder patch, and oxygen tab.
