Su-Su-Suit provides air permeability as high as 180cc

The incredible innovations in Australian Merino wool continue with the launch of a new summer wool suit that breathes like a T-shirt.
Developed by Japanese clothing company Aoyama Trading in collaboration with Woolmark Japan, the Su-Su-Suit is a lightweight garment with a unique level of air permeability.
The suit was originally designed to support Japan's Cool Biz movement, launched in 2005 by the Japanese Government. The campaign asked office workers to shed jackets and ties, and set the air-conditioning in offices at 28C degrees, to save energy and meet the target CO2 emission rate set by the Kyoto Protocol.
The fabric specially developed for the Su-Su-Suit provides an air permeability as high as 180cc – allowing six times as much air to pass through it than a normal dress shirt.
The unique level of fabric breathability was achieved using the special Australian Merino wool yarn “tornado-twisted” with ceramic-mixed filament to reduce fibre-ends (make the yarn less fuzzy.) When this yarn is woven, the fabric also has a coarser weave which dramatically improves air permeability.
The ceramic-mixed fibre also gives heat insulation effects. When combined with its superior breathability, the fabric enjoys doubled cooling effects equal to around a 4C degree reduction in temperature compared with that of conventional mid-summer suiting fabrics.
Su-Su Suits were planned and developed by a team of specialist companies covering rawwool, textiles, making-up and marketing including Aoyama Trading, Nihon Keori and The Woolmark Company, with full support by Australian Wool Innovation (AWI) from fabric development to marketing. A total of 30,000 units were produced for the summer 2007 launch.
