Armi Ratia founded Marimekko in the ’50s, and she believed a woman should be able to run in a dress if they wanted to. This adidas running t-shirt is designed with the same bold spirit that made the Finnish label ahead of its time. Wear the tee on race day, and the pattern will make it easy for your friends to find you. A loose cut gives you free movement, and AEROREADY keeps you dry.
