The Most Sustainable Running Clothing (2026)

Expert Advice on Running Clothing
The Most Sustainable Running Clothing (2026)

Twice a year we carefully choose our clothing range. We want you to fall in love with the products we love ourselves. It's not only about the colour, or cut, or the lightness of the fabric – although we love all of that too! – we also care how each product has been made.

We ask the same questions as you: What's the environmental impact of the products we stock? What's the carbon footprint of having these lovely items on our hanger? Are they made in a safe workplace, and in a socially responsible way? Is this material long-lasting? Is the fabric made from recycled materials?

Our goal is to select ranges that are going to last you a long time and perform really well, manufactured in a responsible way.

WHAT DO WE ACTUALLY MEAN BY SUSTAINABLE?

NATURAL FIBRES

Merino wool, Tencel, Modal and organic cotton. Merino wool (always Mulesing free) is used by some brands not only for winter baselayers but also short sleeve tees as it has natural thermoregulating properties. Cotton isn’t used much in running clothing, when we select an item with cotton we ensure it’s organic and combined with other fibres to ensure it's moisture-wicking.

RECYCLED MATERIALS

Many brands are now using polyester made from recycled plastics. The most conscious brands reach for REPREVE® with its traceable yarns.

ENVIRONMENTAL IMPACT

Reducing carbon emissions, as well as responsible use of chemicals and water. Recycled packaging. Products that are Bluesign® approved. Certified B Corp brands. Brands that work with local charities to support communities, and ensure fair working practices throughout the supply chain. Most running garments are durable, which reduces waste.

Sustainable Running Bottoms

For the bottom half of your body, select depending on the conditions you'll be running in, how long you'll be out for, how fast you'll be running – and therefore how warm you're likely to get.

Some shorts offer an inner lycra layer that fits close to the skin. This doubles as protection from unwanted friction. It also provides extra storage space, such as a drop-in pocket for your phone.
