The ANJ-4/AN-6552 was a late WW2 development of a sheepskin jacket designed to be more accommodating in a cockpit in lieu of the bulkier B-3 sheepskin, which was used by all aircrew but was not as comfortable in a tight confine. Experimental test samples were developed of this same jacket in leather with various types of linings for warmth and flexibility to accommodate those crewmembers that needed a lighter less bulky material. So a leather version of the ANJ-4 was drawn up and sampled but never produced.
Cockpit has taken this concept and created our own engineered version of this universally useful jacket, as it permits the wearer to use its two-way zip to sit in a cockpit or a vehicle and loosen the waist as well as side buckles to tighten it to keep the wind out, with added zip sleeves, similar to the British flight jackets, to allow gloves to fit under the sleeves; great for motorcycling as well. The leather is a supple but durable vintage lamb and carries the features of its sheepskin predecessor with USN style patch pockets and a large real shearling collar with throat latch to keep wind out and warmth in. The modern lining is our WW2 parachute pattern nylon quilted to trademark Primaloft for extra warmth, softness and flexibility and two added inside pockets for modern convenience. A truly unique, contemporary jacket with a vintage configuration that sits slightly lower than the sheepskin jackets of the same era for additional weather protection. Proudly made in the USA.
