It might surprise you to know that your favourite gym wear brands probably aren't as sustainable as you think. If a brand creates eco-friendly fitness apparel it means they make conscious choices to minimise the negative impacts of creating clothes on the planet. But, it goes further than that. It also means sourcing materials from sustainable and renewable sources, minimising carbon emissions and ensuring fair labour practices. And historically, gym clothes haven't been the most environmentally friendly due to the stretchy synthetic fabric they're usually made from, which is heavy in plastics and other oil-derived materials.

The best eco-friendly fitness apparel, at a glance:

• Best eco-friendly workout jacket: TALA DayFlex Zip Through Jacket - View on TALA

Now, more people than ever are investigating a brand's ethical practices and the fabric the clothes are made from before making a purchase. This is great because we hold brands responsible and drive positive change in the fitness-fashion industry.

Why should I choose eco-friendly fitness wear?

The most attractive thing about choosing fitness clothes that are made sustainably is that you know you're investing in a piece you'll be able to wear again and again (and again). Think about it: our workout clothes are put up with A LOT. All that sweat, dirt and stretching. Sustainable clothes are made to last and are less likely to stress, rip, or shrink. As a result, you'll save money in the long-run replacing sports bras, gym leggings and workout tops that will just end up in landfill.

It's no secret that the fashion industry are a big polluter. Choosing eco-friendly fitness apparel has a lower environmental impact as they're often made from organic cotton, hemp or even bamboo. With a whopping 90% of activewear being made from plastic that cannot ever biodegrade, it makes a real difference buying from somewhere that doesn't make their clothes from this.

Also, sustainable brands are more likely to pay their workers fairly. Fair Trade guidelines ensure that workers receive fair wages, they're treated ethically and the working conditions are safe. Most eco-friendly brands are transparent about the factories and facilities where their products are made, which means they're probably more ethical.

Buying from an eco-friendly brand will ensure your workout wear will last from one session to the next, have a lower impact on the planet and make sure the people who make your clothes are paid fairly. So, leaving you with a clear conscience, but also with a brand new workout wardrobe.

Eco-friendly fitness apparel: A buyer's guide

With more and more brands offering sustainable gym wear, or at least, partly sustainable workout wear (brands like Adidas and Nike have introduced eco-friendly initiatives but are yet to make their entire brand more conscious) it can be difficult to decipher bamboo from recycled nylon.

Our buyer's guide is here to clarify any worries you might run into when searching for a new workout wardrobe, or if you're worried about what to wear to a gym session.

What is the best natural fabric for athleisurewear?

When it comes to choosing a fabric for your sustainable athleisurewear, bamboo is the frontrunner. Renowned for its luxuriously soft texture and ability to keep you cool during sweaty workouts. Bamboo is also surprisingly sweat-wicking, as the material works to swiftly absorb sweat. Plus, it boasts natural antibacterial properties, combatting odour-causing bacteria to keep you smelling fresh all day long.

An alternative to bamboo is organic cotton, which has great eco-credentials as it's made without the use of harmful pesticides or synthetic fertilisers. Its cultivation prioritises soil health and biodiversity, fostering a better relationship with the environment. The feel of organic cotton itself is smooth, soft and breathable, which makes it great for workout wear.

Furthermore, there are a couple of other alternatives; like hemp or recycled polyester, but bamboo and organic cotton are two of the most common.

What fitness brand is the most environmentally friendly?

Pangaia is one leading fitness and athleisurewear brand that are extremely popular for both women's gym clothes and men's too. With their focus on eco-friendly materials and an ethical practice, Pangaia's environmental rating is 'good'. To make their clothes, this sustainable brand uses offcuts to minimise textile waste and they use natural dyes in most products. In addition, their packaging is compostable to ensure no cardboard or paper goes to waste. Other brands that deserve a mention are Patagonia, BAM Clothing and influencer Grace Beverley's brand TALA.

Why is eco-friendly fitness apparel more expensive?

Sustainable fitness wear often has a higher price tag due to the processes and premium materials that are involved in the production. Unlike fast-fashion activewear, which may prioritise cost-cutting measures to make their items cheaper for the buyer, eco-friendly brands will invest in sustainable sourcing, ethical labour practices and manufacturing techniques. For example, organic cotton and recycled polyester will be more expensive than ordinary cotton and polyester.

Additionally, certifications and standards that ensure a brand is being honest about their eco-friendliness require additional investments. Fair Trade or the Global Organic Textile Standard (GOTS) is a great label to have, but it comes at an extra cost.

Although the initial price of eco-friendly fitness apparel may be higher, investing in sustainable clothing is not just a singular purchase. It's a commitment to sustainability, ethical practices and the health of both people and the planet.
