Guide to Sustainable and Eco-Friendly Activewear

The activewear industry has an environmental problem. Fast fashion practices, synthetic materials derived from petroleum, water-intensive manufacturing, and short product lifecycles all contribute to a significant ecological footprint. But as consumers become more environmentally conscious, brands are responding with innovative sustainable options. This guide explores how to make eco-friendlier choices when shopping for workout clothes—without compromising on performance.

The Environmental Impact of Activewear

Understanding the problem helps inform better choices. Traditional activewear production impacts the environment in several ways:

Material Production

Most activewear is made from synthetic fabrics—nylon and polyester—which are derived from petroleum, a non-renewable resource. The production of these materials is energy-intensive and releases greenhouse gases. Additionally, synthetic fabrics shed microplastics during washing, which end up in our waterways and oceans.

Manufacturing Processes

Fabric dyeing and finishing processes use significant amounts of water and chemicals. Poorly regulated facilities may release toxic wastewater into local environments. The carbon footprint of global supply chains—shipping materials and finished goods around the world—adds to the environmental toll.

Product Lifecycle

Fast fashion encourages frequent replacement of workout gear, leading to overconsumption. When discarded, synthetic activewear doesn't biodegrade—it can persist in landfills for hundreds of years.

Sustainable Material Options

Recycled Polyester (rPET)

Recycled polyester is made from post-consumer plastic, often plastic bottles. This diverts waste from landfills and oceans while requiring less energy to produce than virgin polyester. Importantly, recycled polyester performs identically to virgin polyester—you're not sacrificing quality for sustainability.

Many major brands now offer rPET options. Look for specific claims about recycled content percentage and certifications like Global Recycled Standard (GRS).

Econyl (Regenerated Nylon)

Econyl is regenerated nylon made from waste materials including fishing nets recovered from oceans, fabric scraps from manufacturing, and industrial plastic waste. The regeneration process can be repeated indefinitely without losing quality. Econyl offers the same softness and performance as virgin nylon while helping clean up ocean pollution.

Organic Cotton

For low-intensity activities and everyday wear, organic cotton offers an alternative to synthetics. Organic cotton is grown without synthetic pesticides or fertilisers, uses less water than conventional cotton, and doesn't shed microplastics. However, it's important to note that organic cotton doesn't wick moisture like synthetic fabrics, so it's not ideal for high-intensity workouts.

TENCEL™ and Other Plant-Based Options

TENCEL™ (lyocell) is made from sustainably sourced wood pulp using a closed-loop process that recycles water and solvents. It's biodegradable, soft, and breathable. While not as common in performance activewear, TENCEL blends are appearing in more athletic products, particularly for yoga and low-impact activities.

Natural Rubber and Bio-Based Elastanes

Some brands are exploring alternatives to petroleum-based elastane (spandex). Natural rubber and bio-based elastanes made from plant sources offer sustainable stretch options, though availability is still limited.

Beyond Materials: Sustainable Practices

Ethical Manufacturing

Sustainability isn't just about materials—it's also about how products are made. Look for brands that:

• Pay fair wages to workers
• Provide safe working conditions
• Use renewable energy in manufacturing
• Minimise water usage and chemical discharge
• Maintain transparent supply chains

Certifications like Fair Trade, B Corp, and bluesign® can help identify ethically produced products.

Local Production

Products manufactured closer to home have smaller carbon footprints from transportation. In Australia, some brands produce locally or source from nearby countries, reducing shipping distances. Local production also often means better oversight of working conditions.

Durability and Longevity

Perhaps the most sustainable activewear is what lasts longest. A higher-quality item that you wear for years is more environmentally friendly than cheap pieces that need frequent replacement. When shopping, consider:

• Quality of construction and materials
• Brand reputation for durability
• Timeless styles over trends
• Care instructions that maintain quality

Reducing Your Activewear Footprint

Buy Less, Choose Well

The most sustainable purchase is often no purchase at all. Before buying new activewear, ask yourself:

• Do I really need this, or do I want it?
• Will I wear this at least 30 times?
• Does this fill a genuine gap in my wardrobe?
• Am I buying this because it's on sale?

Care for What You Have

Proper care extends the life of your activewear:

• Wash in cold water (saves energy and protects fabrics)
• Air dry instead of using the dryer
• Use a microfibre-catching laundry bag to reduce microplastic release
• Follow care instructions to maintain quality

Second-Hand and Rental Options

Consider buying pre-owned activewear through platforms like eBay, Facebook Marketplace, or specialty second-hand athletic wear sites. Some brands also offer rental programs or buy-back schemes where you can return old items for recycling or resale.

Certifications to Look For

Independent certifications help verify sustainability claims:

• Global Recycled Standard (GRS): Verifies recycled content in products
• OEKO-TEX Standard 100: Tests for harmful chemicals in textiles
• bluesign®: Ensures responsible use of resources and chemicals
• Fair Trade Certified: Ensures fair wages and working conditions
• B Corp Certification: Verifies overall social and environmental performance
• GOTS (Global Organic Textile Standard): For organic fibres

Sustainable Brands Making a Difference

Several brands have built their business models around sustainability:

Girlfriend Collective: Made from recycled water bottles, inclusive sizing, transparent about manufacturing in Vietnam.

Patagonia: Pioneer in sustainable outdoor wear, offers repair programs, uses recycled materials.

Pact: Organic cotton basics with Fair Trade certification.

Organic Basics: European brand using recycled and organic materials with focus on longevity.

The Microplastics Challenge

Even sustainable synthetic activewear sheds microplastics when washed. To minimise this:

• Use a Guppyfriend bag or similar microfibre-catching laundry bag
• Consider a washing machine filter designed to catch microplastics
• Wash less frequently (spot clean when possible)
• Wash on gentle cycles with cold water (less fibre release)

End-of-Life Options

When your activewear has truly reached the end of its life:

• Donate: If still wearable, donate to charity shops
• Recycle: Some brands accept old clothes for recycling
• Repurpose: Use old leggings as cleaning rags or for craft projects
• Textile recycling: Look for local textile recycling programs

Making sustainable activewear choices doesn't mean compromising on performance. Today's eco-friendly options offer the same quality and functionality as conventional products while reducing environmental impact. Every purchase is a vote for the kind of industry you want to support. By choosing mindfully, caring for what you have, and supporting responsible brands, you can maintain an active lifestyle while treading more lightly on the planet.
