Mammut shirts fit with We Care policy

bioRe cotton part of environmentally friendly strategy


Continuing its commitment to its corporate responsibility plan outlined in 2018, using bioRe cotton in the manufacture of its range of climbing shirts.

The outdoor company says it wants to significantly reduce the environmental footprint of its collections and ban environmentally damaging substances from supply chains as part of its We Care strategy, focusing on the increased use of organic cotton to minimise the environmental footprint of its products. Life cycle analysis indicates that organic cotton consumes 91 per cent less water compared to conventional cotton and causes 46% less greenhouse gas emissions.

BioRe cotton is organically grown without genetic modification and under fair conditions by 6,000 small farmers in India and Tanzania. Since 2012, Mammut has been working with the Swiss fair-trade focused company Remei for its procurement.

Remei assures small farmers a purchase guarantee and pays them a 15 per cent organic premium on the regional market price. In additon, Remei advocates the training of farmers in organic farming methods.

Beyond the quality of bioRe fibre, Mammut places great importance on sustainable production throughout the entire textile supply chain. Remei-approved spinning mills are used to spin the yarn. The yarns and textiles are then dyed in strictly controlled dye works. For printing, embroidery and finishing, Remei has set up specific Mammut production lines with its long-standing production partner.

All products marked as bioRe sustainable textiles are also CO2‑neutral. Mammut attaches great importance to transparency in its WE CARE program. The bioRe® cotton climbing t-shirts offer consumers the opportunity to trace the entire textile chain all the way back to the farmers. The traceability code required for this is sewn into the Mammut Climbing T-shirts and can be entered at
