Tretorn was established in Sweden in 1891 as a manufacturer of rubber boots. Having improved their initial poor-quality rubber, the company moved into various fields - shower caps, tires and tennis balls, for instance. Having designed many classic lines in footwear, outerwear and tennis equipment over the years, they were reinvented in the noughties as a trendsetter; their timeless, minimalist and practical design aesthetic being both historic and forward looking.
