Rediscover a rare Grasshopper Club Zürich piece with this 1998/99 home jersey from Adidas. True to the iconic half-and-half blue and white design, it features the Leukerbad sponsor, used at the very beginning of the season before the official switch to Tele 24. This detail makes this jersey particularly sought after, as it represents a transitional version rarely seen on the market. A true treasure trove for collectors of vintage Swiss jerseys and GCZ enthusiasts.

To preserve your vintage jersey, hand wash or machine wash cold (30°C max) on a delicate cycle, always inside out. Use a mild detergent, without bleaching agents. Avoid tumble drying, ironing directly on the flocking, and prolonged exposure to sunlight. Air dry it, flat or hanging it upside down. For best preservation, store it in a dry place away from light.
