Sustainable gym wear UK: 13 ethical activewear brands to wear for your workouts

Posted by for Fashion

We’ve rounded up an edit of eco-conscious gym wear pieces from sustainable and ethical brands that will look and feel great to work out in, at home or in the gym

From sustainable denim to vegan leather bags, there are a myriad of ethical and stylish updates you can make to your wardrobe. Now that we are back at the gym(or working at home more)  your workout kit too is poised for a sustainable makeover.

But just as you may need a refresher on which machines to use after so long away, your gym clothes will probably need an update too. 

Sadly, the majority of all synthetic activewear is made from plastic, and as all the squat-lovers out there will know, the pressure we put on our kit makes replacing our leggings and sports bras an inevitability. So what’s the solution to this sustainable dressing dilemma? Enter the fashion-led activewear brands who are as environmentally conscious and performance driven as they are stylish

When it comes to sustainable shopping, materials and how they’re made are key. Consider Tencel – the ultra-luxe fabric that you’d never guess is produced from wood pulp. Smoother than cotton and (whisper it) softer than silk, once you’ve worked out in a Tencel vest, you’ll love it for how incredible it feels against the skin as well as the fact that it has a significantly lower environmental impact than the cotton alternatives.

Maybe the first step of shopping ethically is admitting that you will, most likely, not end up keeping that must-have thing forever. So when you’re buying new workout kit it’s vital to consider all parts of your new piece’s lifecycle. ecoYoga’s yoga mats are made from 100% natural rubber, making them a completely biodegradable alternative to entirely synthetic alternatives. 

Whether you’re a runner or a yoga lover, can’t say ‘no’ to a 7am swim or prefer to break a sweat on the rowing machine, we’ve found 12 of the best ethical and sustainable activewear to reinvent your workout in 2021. 

  • Gym + Coffee
