Standard combat clothing included a utility uniform worn underneath the winter garment, which was an improved carryover of World War II herringbone twill clothing material. Boots, leggings, field equipment and weapon technology remained the same.
To brave winter, Marines donned several layers to enter the subzero climates to the north.
The parka was lined with alpaca fleece while the outer shell was made of a cotton canvas. Marines did not have standard cold-weather clothing, so their iconic parka actually came from the Navy, the M1947 Navy deck parka.
Alpaca fleece is the natural fiber harvested from an alpaca, is soft and durable, and can be light or heavy in weight.
The 1943 field jacket and trousers were heavy cotton outer garments designed to be worn over the M1941 service uniform. They could also be worn with an inner liner for weather protection.
To combat the frigid temperatures, several undergarments were worn including: cotton-wool blend undershirts, wool boot socks worn over regular socks and cotton-blend long underwear called drawers. (Not pictured)
Accessories such as mittens, gloves and scarf were made of wool.
The M1943 camouflage pattern poncho was a reversible green or brown, similar to the World War II camouflage poncho. It was made of two cotton cloth pieces bonded with a thin film of rubber in between to make it waterproof. Unlike the Army's, the Marine Corps' poncho did not have a hood.
