The yellow shirt from the Nostalgia collection, on the occasion of 50 years stadium anniversary, has a front print on the left side of the chest and a large back print. On the front print you can see a floodlight pole and the coordinates of the stadium are embroidered above. The back print consists of four illustrations from different periods of our stadium, above it is an embroidery with "Since 74" and the coordinates. The collection is made from organic cotton from India (GOTS in conversion) and carries the seal Fairtrade Textile Standard, Fairtrade Cotton and Green Button. The green button is a state seal for sustainably and socially produced textiles. GOTS is the Global Organic Textile Standard that defines recognised requirements for organic textiles. GOTS-certified textiles offer trusting safety for sustainable raw material harvesting as well as environmentally and socially responsible production. Fairtrade stands for sustainable trade and production and provides more transparency on the market with Fairtrade advantages such as fairer prices, better trading conditions and more stable contracts. The Fairtrade textile standard is used to strengthen workers and improve wages and working conditions in the textile industry.
