The fabrics used on solstice shirts (except the wool shirt) are fully Swiss made from the spinning of the cotton yarn to the finishing within an 80km circle around Zürich. Cotton is not growing in Switzerland; so certified organic cotton is imported from the United States.
Here is the fabric story in 5 steps:
- Cultivation: the certified organic supima® cotton is cultivated in the US
- Spinning: the chosen extra-long staple cotton fibers are spun by Hermann Buehler (the last spinner in Switzerland and the worldwide leader) near Winterthur.
- Weaving: the Yarn is then woven through a mechanical process to a fabric by Jenny Fabrics in Glaris.
- Finishing: the finishing processes include pre-treatment, dyeing, mechanical and chemical finishing are made by Cilander in Herisau. Usage of environmentally harmful chemicals is prohibited.
- The fabrics: are marketed by Stotz & Co. Ltd in Zurich and then delivered to Solstice.
On top, the products that carries the Swiss Organic Fabrics label ensures that all the production steps are made in Switzerland...
… and also guarantees high environmental standards for the manufacture of textiles as all operations must be certified according to GOTS (Global Organic Textile Standard) and Oko Test 100 with 3rd party assessment.
The swiss+cotton mark is the quality mark for the finest and choicest Swiss cotton textiles.
The garments are then manufactured in Portugal, in an atelier specialised in shirts’ conception.
