Synthetic material – especially polyester and nylon – has shaped the outdoor and adventure industry we know today, with outdoor gear lauded for its performance and durability. It’s tough, breathable, warm, waterproof, wind-resistant and lightweight – a step change from the gear of earlier explorers who were kitted out in natural fibres such as cotton, wool and down.
More recent climbing and exploration achievements wouldn’t have been possible with old-fashioned gear, says Gavin Davidson, design manager at Macpac. “Expeditions that took months and required an army of support teams are now being completed by small teams in record time – thanks, in some degree at least, to modern gear.”
But with this comes the uncomfortable truth that about half of the textiles used in outdoor clothing are materials that leave a big environmental stain. Synthetic fabrics are made from petroleum with a huge amount of water being used in the process. The fabrics are known to shed thousands of polluting microplastics or microfibres into the environment, which can take hundreds of years to degrade and decompose. That’s a worldwide problem when less than one per cent of clothing is recycled into new fabrics. The European Commission claims it leads to a garbage truck of clothing going to landfill or incineration every second. That’s 92 million tonnes globally every year, according to one 2020 estimate.
As well, more than 800 chemicals and dyes, including toxic perfluorinated compounds also known as PFCs, are used in the manufacturing processes. These can result in water pollution and are linked to impacts on human health.
