_We find that as Buzz Ricksons 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._ The Spec 55-J-14, adopted by the Navy Civil Aviation Bureau since the late 1940s, was the first jacket to be called the "G-1". The design that started with M-422 is a series of jackets that have been standardized through AN6552 and AN-J-3A jointly owned by Land and Sea, and their appearance and details have not changed significantly. There is no size notation on the main label, and a size ticket is inserted. Leather tanned with full vegetable tanning tends to be tight, but the goatskin with its flexible fibrous properties eliminates it.
