Club Tech Tracksuit 1979

Sergio Tacchini's Club Tech tracksuit from the late 1970s is the most undervalued Italian sportswear item in the current market. The brand founded by Italian tennis champion Sergio Tacchini in 1966 outfitted John McEnroe, Pat Cash, and Vitas Gerulaitis at their peak. The white polyester with colored stripe detailing created a template for luxury sportswear that Lacoste and Ralph Lauren studied carefully. Available: $60–$180. As tennis wear's cultural rehabilitation continues, Tacchini will follow Fila's trajectory. Upside: $300–$800.
