The best sustainable men’s activewear for the gym, hiking, swimming and more…

After a new pair of summer beach shorts, a hoodie for the gym or perhaps a lightweight jacket for hiking?

Finding activewear that is both practical and comfortable, all while making you look and feel good, isn’t easy at the best of times – let alone when you add the criteria of sustainability on top.

That’s why below we’ve compiled a list of some of our favourite sustainable activewear UK items for men that, if you ask us, tick all the right boxes.

Each of the brands we feature offer better quality, longer-lasting and sleeker looking alternative apparel to the fast fashion sportswear industry. They prove that on-trend, stylish and functional design doesn’t need to come at the cost of the earth.

The Live Frankly seal of approval:

These are really good brands, doing good things. To be included in this list, each brand has been given the Live Frankly seal of approval. We are not a certification, but we talk with every brand and ask them to complete a comprehensive questionnaire about their ethical standards before we feature them. No brand is perfect – we’re all operating in an imperfect world – but only purpose-driven brands that are working to change things for the better are allowed on Live Frankly.

We ask that workers’ rights and pay are ensured across the supply chain, that brands use sustainable materials and want to know about their governance structures. This means you can be confident these brands are some of the most ethical and sustainable around. If you have any questions, please get in touch.
