This is the sweater reminiscent of the original A-1 mechanic's sweater worn by USAAF ground crews during World War II. Favored for its overlapping v-neck that pulled easily over mechanics' overalls, it was originally made from worsted wool, but this one is improved by using 100% cotton for comfort. Like the original, it uses a rib-and-rack weave on the cuffs and waistband that provides a relaxed fit, allowing ease-of-movement, one of the reasons it was worn by wartime mechanics as well as the pilots they supported. Enhanced for modern wear, the sweater includes suede elbow patches for durability and a button-down shawl collar for locking out the cold. Olive. Sizes M (42), L (45), XL (48). (1 lb.)
