The Best Eco Friendly Activewear For Your Workout

Say goodbye to recycled bottles shedding microplastics in the oceans! That’s thanks to this truly eco friendly activewear

By Lora O’Brien

Whether you like to pound the pavements with a run or grab your mat and relax with some yoga, exercise plays a pivotal role when it comes to your health. And of course, whilst you’re getting sweaty,  you’ll want the clothes that are so close to your skin to be made of natural – not petrol-based – fibres. Here’s why.

Why choose natural fibres for eco friendly activewear

Did you know that aside from being a burden on landfills, most workout gear is pretty toxic, too?

Sure, they might offer some stretch for working out easily. Some even wick sweat away from your skin. But there’s no denying activewear made from petrol-based materials or recycled plastic isn’t good for us, or the planet! These synthetic materials are incredibly slow to biodegrade, and they also leave micro-particles of plastic in our water systems every time you wash them.

What that means is that you, as well as wildlife, including birds and fish – end up consuming those fibres. Yep – you’re literally eating bits of your own clothes! 

These tiny plastic pieces can also absorb high concentrations of poisonous substances. Even those that escaped into our oceans years ago, such as DDT and other pesticides. Before the fibres reach the ocean, there’s a also good chance they’ve soaked up toxins from detergents and fire-proofing chemicals. Some of these pose a threat to our liver, kidneys and nervous system. Others are highly toxic to aquatic life. Every time you wash those yoga tights, you’re giving the oceans – and later, your body – another dose of pollution.

And as we all know, your activewear gets washed a lot! Eco friendly activewear is the only solution.

The benefits of natural fibres

Overall, eco friendly activewear made from natural fibres has many great benefits. For example, these materials are biodegradable, and are thus more sustainable. They’re also kinder to your skin, and don’t pollute waterways – especially if they’re dyed naturally.

Be on the lookout for accreditations such as the GOTS and the Fairtrade Textile Standard when purchasing eco friendly activewear. Also try to choose better alternatives, such as innovative fabrics like TENCEL whenever possible.

Types of fibres to look for in eco friendly workout gear

TENCEL fibres are made from sustainably sourced wood pulp and fully revert to nature. Providing the same high-performance qualities as plastic fabrics, TENCEL is both breathable and biodegradable. These soft fibres will help to keep your body pleasantly cool and dry with their natural comfort and versatility. It’s perfect for workouts!

Hemp is a great substitute for cotton and is more ethical than both cotton or bamboo. The sustainable fibre has been used in clothing for thousands of years, and there are loads of reasons why! Not only is hemp a sustainable and durable fabric to wear when it comes to activewear, but it’s also breathable, hypoallergenic, antibacterial and biodegradable.

Organic cotton is one of the most popular fabrics when it comes to activewear. The natural textile is non-GMO and uses natural fertilisers and pesticides, instead of the very hazardous chemicals used for conventional cotton. Though it does require a ton of water to grow, it uses 88% less water and 62% less energy to produce than non-organic cotton. The end result is eco friendly activewear that is light, durable, comfortable, moisture-wicking and fast to dry. Not to mention it’s biodegradable.
