Organic Cotton Tracksuits: The Best Sustainable Sets in Australia
These are the best organic cotton tracksuits and lounge sets available in Australia in 2026, from Melbourne-made matching sets and custom-fit Tencel trackpants to Australian merino for cold climates.
There’s something undeniably satisfying about a matching set you can throw on and instantly feel comfortable in. The problem is, most fast fashion tracksuits are made from polyester fleece, which is plastic. It’s derived from fossil fuels, sheds microplastic fibres every wash, and it’s not breathable. Organic cotton does the same job, and unlike polyester, it gets softer the more you wear it.
What to look for in a sustainable tracksuit
It all starts with the fabric. Look for Australian-grown cotton or organic cotton grown without synthetic pesticides, ideally GOTS-certified, which covers the dyes and finishing as well as the farming. Bamboo and Tencel are naturally derived fibres that are softer and lighter, which are great if you tend to overheat. Merino wool is the warmest natural option if your winters are proper cold rather than just Brisbane cold.
For Australian made pieces, an Ethical Clothing Australia accreditation means the people sewing your clothes are paid fairly. And as always, the most sustainable trackies are the ones you already own. If you’re buying new, buy the best quality you can afford, look after it, and expect to wear it for years.
A quick note about our brand guides
The Green Hub has been covering sustainable fashion for more than a decade. Our guides are put together by sustainability researchers and industry specialists, drawing on independent research and years of reporting on the space. We don’t include brands lightly. We consider material quality and how transparent a brand is about its production, with preference given to clothes designed to last.
Where to buy sustainable tracksuits in Australia
Organic Crew
Organic Crew’s loungewear is made in Melbourne from certified organic cotton. The best-selling Crew Pants are made from thick 100% organic French terry, and the matching sweater and jogger sets come in soft tonal colours you can mix and match across seasons. Some pieces are now made in India, with the Australian-made range clearly labelled on their site.
Bassike
Bassike has been making its signature organic cotton jersey in Australia since 2006, with around 90% of production still happening locally. Their track pants are made from heavyweight organic cotton fleece with an elasticated waist and ribbed cuffs, in both men’s and women’s fits, with matching sweats to complete the set. They’re an investment, and the kind of piece you’ll still be wearing in a decade.
DK Active
DK Active is made ethically in Brisbane, where design, manufacturing, warehousing, and distribution all happen under one solar-powered roof. They use organic cotton, hemp, and recycled fibres across the range, and their activewear is designed to be sweated in and made to last. If your tracksuit needs to do more than the couch, start here.
Citizen Wolf
Citizen Wolf makes custom-fit clothing in Sydney using their Magic Fit technology, and their sweat pants are cut to your measurements from French terry Tencel. They’re Ethical Clothing Australia accredited, certified carbon negative, and offer free repairs for life. Each pair is made to order, so allow a little extra time for delivery.
Toorallie
A Melbourne label with a 200-year merino legacy. Pieces are made from superfine 17.5 micron Australian merino, soft enough to wear directly against your skin, and all of their wool is Responsible Wool Standard certified, which guarantees non-mulesed sheep. Merino is naturally odour-resistant too, so these are pieces you can wear all week and wash rarely. If you’ve always found wool scratchy, Toorallie is worth trying.
Cloth & Co
Cloth & Co is an Australian brand that makes luxe-looking and feeling loungewear sets, and the waffle knit range is divine. They partner with women’s cooperatives and artisans in India, and all stages of production are independently certified from farm to stitch. Every piece is made with natural cotton sourced from organic and regenerative farms using natural dyes, so their pieces can be recycled, repurposed, or composted at the end of life.
Pangaia
Pangaia’s colour-pop tracksuits are made from organic cotton using natural botanical dyes and a recycled wastewater system, and the brand develops its own bio-based fibres for the rest of the range. Fun fact, they treat their fabrics with antibacterial peppermint so your clothes stay fresher for longer and you can wash them less.
Mate The Label
MATE makes its organic cotton sets in Los Angeles, with almost all production happening within a few kilometres of their headquarters. Having such a localised supply chain allows the brand to consider the full life cycle of their products and how sustainability fits in at every step. The sets themselves are seriously stylish, the kind you can wear from the loungeroom straight out to lunch, and they ship to Australia.
Frequently asked questions about sustainable tracksuits
Are cotton tracksuits warm enough for winter?
Yes, for most of Australia. A thick organic cotton French terry or fleece tracksuit handles Queensland and coastal winters comfortably. For genuinely cold climates, merino is the warmer natural option, trapping more heat at less bulk than cotton, while staying breathable indoors.
What fabric is best for a tracksuit?
Organic cotton French terry is the best all-rounder: warm, breathable, and durable without shedding microplastics the way polyester fleece does. Bamboo and Tencel are softer and lighter, merino is the warmest for winter, and hemp blends last the longest.
Why buy an organic cotton tracksuit?
Organic cotton is grown without synthetic pesticides, uses healthier farming practices, and is usually softer and longer lasting than conventional cotton because it’s processed more gently. Certified organic also means the dyes and finishing meet safety standards, which matters for something you wear against your skin all day.
How do I make a tracksuit last longer?
Wash cold and inside out, skip the dryer, and don’t wash after every wear; airing is enough unless they’re actually dirty. Cotton fleece softens with age, and a fabric shaver handles any pilling on high-friction spots.

Sustainability is an ongoing journey, and brands evolve over time. We do our best to keep this guide accurate and up to date, but certifications lapse and links occasionally break. If you spot something that needs a refresh, let us know.
The brands featured meet a range of ethical and sustainable standards, from certifications and living wages to transparent supply chains. That said, ethics are personal. This guide doesn’t cover every factor — like use of animal products or local manufacturing — so we always recommend checking a brand’s About page to see if their values align with yours.
