Microfibres are fragments of up to 5mm in length and a fifth the diameter of a human hair, they shed from all fabrics whether that be synthetic or natural. The majority of the microfibres in the environment are released through the laundry process.

It is estimated that over 14 million tonnes of microplastics (generated not just from clothing but other sources too) have accumulated on the floor of the Earth’s oceans. They are consumed by living organisms including plankton, fish, marine mammals, and land creatures. High levels of exposure to microplastics can induce inflammatory reactions and toxicity and play a role in the spread of pathogens and microbes.

The Ridge 100 pullover (1) is made of 100% recycled fibres, with PrimaLoft Bio, which are created to help reduce the long-term impact of microplastics on our oceans, landfills, and waterways. The fibre was chosen because it is lightweight, durable, and warm, meaning it provides premium performance during active pursuits. PrimaLoft Bio is made from recycled bottles and has been optimised to be more appetising to naturally occurring microbes in specific environments. By being consumed by microbes, the fabric is returned to elements found in nature, leaving behind components like water, carbon dioxide, methane, biomass, and humus. In accelerated landfill environments the material will biodegrade by 93.8% in 646 days, in accelerated marine or ocean environments it will biodegrade by 76.6% in 973 days, and in wastewater environments it will biodegrade by 17.8% in 241 days.
