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 is a reproduction of a jacket for prisoners of war prepared by the U.S. Navy during World War II. The fabric used is a hickory stripe, and the shape is the same as the Navy's denim utility jacket, with a rounded shawl collar and patch pockets on the bottom. The buttons are change buttons that are fastened from the back with a G-shape ring. Unlike tack buttons, these buttons do not require a special hammer, and because they are not thread fastened, they are a rational detail that will not come off due to thread breakage.
