As one of the biggest buyers of ultra-fine Merino wool, Ermenegildo Zegna has encouraged, supported and rewarded the efforts of the Australian wool industry since 1963 in the production of finer and softer wools. Despite this, the former Australian Prime Minister Paul Keating was criticised by the Liberal Party for wearing his favourite Zegna double-breasted suits as it has been a tradition since the 1960s that Australian Prime Ministers wear Anthony Squires suits.
In 2002 the Ermenegildo Zegna Vellus Aureum Trophy was launched for wool that is 13.9 micron and finer. Wool from Australia, New Zealand, Argentina and South Africa may be entered and a winner is named from each country. In 2010 a soft ultra-fine, 10-micron fleece, from Windradeen, New South Wales set a new world record in the fineness of wool fleeces when it won the Ermenegildo Zegna Vellus Aureum International Trophy.
