Barbour Men's Union Jack International Waxed Jacket. Although you may not be pulling stunts like Oliver and Lorenzo this jacket will have you pulling focus whenever its worn. Barbour has gone back into their archives to recreate the Union Jack International jacket. It was the original jacket, which was worn by virtually every British International motorcycle team from 1936 to 1977 that inspired this design. With the authentic size flag on the chest and bold union flag lining this jacket promises to ooze style. The slanted map pocket on the International range has been derived from Barbour's rich heritage. It was designed for practical purposes, as are most features on a Barbour jacket, to allow the wearer ease of access.
