While casually browsing in a sports store in Chelsea, Martina was struck by the softness and unique look of Tonic active wear. After wearing them for the first time at an exhibition match at Wimbledon in 2010, Martina approached the company with the idea of launching a tennis collection. The outcome of this collaboration is a technical line which brings fashion back into tennis wear, respecting the customs rooted in sport history. Tonic Tennis by Martina Hingis emerges from the extremely high standards of the two parties, each recognized for quality and class. Canadian and Swiss cultures synthesize beautifully for Tonic Tennis to create progressive designs with a thoughtful approach to environmental and economic sustainability.
