TL;DR: Polyester is a synthetic fabric made from petroleum through a chemical-intensive process. It's cheap and ubiquitous, but it doesn't biodegrade, releases microplastics, and may pose health risks through skin contact — especially during exercise.
What is polyester made of?
When you check the tag of your favorite Nike shorts, Lululemon yoga pants, or that stylish Alo shirt, chances are you'll find one common thread — polyester. Polyethylene terephthalate (PET), also known as polyester, traces its origins back to petroleum. Yes, the same substance that fuels your car also contributes to the creation of one of the world's most widely used textiles. From high-performance activewear to everyday clothing, polyester has woven itself into the fabric of our lives.
Is polyester biodegradable?
While certain forms of polyester claim to be biodegradable, the majority do not decompose easily. The production and widespread use of polyester contribute significantly to global pollution. The very garments we adore may come at an environmental cost that extends far beyond our closets. It's a sobering thought that prompts us to reconsider the choices we make as consumers.
How is polyester manufactured?
Polyester production is a chemical-intensive process, involving the use of numerous chemicals at high temperatures. This intricate manufacturing dance transforms petroleum into plastic fibers, creating a material that is conveniently cheap to produce but comes with a hidden cost. As consumers, we might not be aware that the polyester we wear could potentially have adverse effects on our health.
What are the health risks of wearing polyester?
As we revel in the comfort and style of our polyester-clad wardrobes, it's crucial to peel back the layers and consider the broader implications. The polyester predicament extends beyond fashion; it's a call to action for a more sustainable and conscious approach to our clothing choices.

What are natural alternatives to polyester?
Perhaps it's time to explore alternative fabrics or support brands that prioritize eco-friendly materials. There are a growing number of options for natural fiber shorts for men and natural fiber activewear for women. Let's not only check the tags for style but also for the story they tell about the impact on our planet and ourselves.
At Wayve, we care deeply about using natural materials when it comes to crafting high quality clothing. We crafted the Quad Short with a built-in merino wool liner and an organic cotton shell. The Only Tee is a premium organic cotton tee, and the Classic Short is a versatile everyday short made from organic cotton. Check them out and see for yourself why polyester activewear will be a thing of the past.
Frequently Asked Questions
Is polyester the same as plastic?
Yes. Polyester is a type of plastic made from petroleum (polyethylene terephthalate). It undergoes a chemical-intensive manufacturing process to transform petroleum into wearable fibers.
Does polyester release microplastics?
Yes. Every time polyester is worn or washed, it sheds tiny plastic particles called microplastics. These can be absorbed through the skin and enter waterways, impacting both human health and marine ecosystems.
What fabrics are better than polyester for activewear?
Organic cotton, merino wool, hemp, and linen are breathable, renewable, and biodegradable alternatives. Merino wool offers natural odor resistance and temperature regulation, while organic cotton provides softness and breathability without chemical exposure.
