We find that as Buzz Rickson’s is made to an original spec, the brand is small compared to modern fits; therefore we advise customers to try at least a size larger than their standard size. We recommend that you contact our stores so our helpful retail teams can offer advice and give exact sizing information before you purchase. This Type M-1943 field jacket is reproduced by "Buzz Rickson's", based on vintage. The M-1943 Field Jacket is the successor of the M-1941 and was developed to integrate the various field uniforms the US Army had adopted until then. The silhouette is relatively loose-fitting as it is designed to be layered to cope with all possible situations. The buttons on the front placket and pocket flaps that fasten with buttons are of the concealed button design, thus avoiding snagging when wearing equipment over the jacket. The material is back-satin, a durable and water-resistant thick cotton satin, colored to olive drab to enhance the camouflage effect. The four front pockets are so large and capacious that a backpack is unnecessary if daily necessities are stored in them. The collar can be worn either open or closed, with the collar up and closed with a chinstrap, an excellent feature that shuts out wind. The basic design of the jacket was highly perfected and was succeeded by the M-51 and M-65 that were subsequently adopted.
