Research has shown that On Running’s materials are responsible for as much as 80% of their carbon footprint. That’s why the brand makes materials their priority.
Running shoes materials
On Running’s running shoes are made of polyester and polyamide. These come from fossil fuels, which further warm the climate. The brand is fortunately aware of this and aims to gradually replace its polyester and polyamide with a 100% recycled variety. In this way, the brand can reduce its CO2 emissions, energy consumption and waste.
Yet recycled polyester is still harmful to the environment when it ends up in the landfill. On Running is, therefore, thinking even more ambitiously and would like to eliminate fossil fuel-based materials completely. They are looking for natural alternatives, such as bio-synthetic fibres, to do so. On Running is determined to use more sustainable materials in the future, and we at COSH can only applaud that!
Clothing Materials
On Running’s clothing today consists of a mix of different fibres. The well-fitting running shorts are made of a blend of polyester and elastane. Both are man-made materials, which leave microplastics behind when washed. The sports t‑shirts consist of 80% polyester and 20% lyocell (a sustainable variant of viscose). The waterproof raincoats are fortunately free of perfluorinated and polyfluorinated chemicals (PFC ). These harmful substances are often found in backpacks and raincoats.
On Running is also currently exploring ways to improve the materials used in its sportswear and running outfits. For example, they are experimenting with possibly converting tree bark into pulp and fibre.
In addition, the brand already partially uses Tencel™ (a sustainable alternative to viscose) in its sportswear. This fibre, in fact, requires less water and processing with chemicals.
Other materials that On Running would like to implement in their clothing are castor oil and sugar cane. The sportswear brand is working with the HIGG index and Life Cycle Assessments (LCAs) to make sure they are choosing the best possible options for the future.
