What Is Fleece?
Fleece is a synthetic fabric celebrated for its warmth, softness, and versatility. Originally developed as an alternative to wool, fleece has become a popular choice for outdoor gear, jackets, and cozy blankets. But what exactly is fleece, and why has it gained such widespread use?
At its core, fleece is made from polyester—a man-made material derived from petroleum. Through a manufacturing process, the polyester fibers are spun, woven, and brushed to create a soft, fluffy texture that mimics the insulating properties of natural wool. This brushing process also creates tiny air pockets within the fabric, which help retain body heat, making fleece ideal for cold weather.
One of fleece’s standout qualities is its breathability. Unlike some other synthetic materials, fleece allows moisture to escape, making it a go-to fabric for activewear and outdoor enthusiasts. It’s lightweight, dries quickly, and resists shrinking, making it a low-maintenance option for everyday wear.
However, it’s not just functionality that makes fleece appealing. Its affordability and accessibility have made it a household name. From micro fleece used in lightweight layering pieces to thicker polar fleece for extra insulation, this fabric comes in various weights and styles to suit different needs. But as you’ll see in later sections, its benefits come with hidden costs to the environment.
Understanding what fleece is and how it fits into our daily lives is the first step in making more informed, sustainable choices. Keep reading to uncover its origins, environmental impact, and the alternatives that might just become your new favorites.

How Is Fleece Made?
Fleece is a synthetic fabric with a surprisingly intricate production process that starts with polyester. Polyester, the backbone of fleece, is derived from petroleum—a non-renewable resource. Let’s dive into how this soft, lightweight material is created and explore innovations making fleece more sustainable.
From Plastic to Fabric
Polyester Production: The journey begins with crude oil. Through a chemical process, petroleum is refined to produce polyethylene terephthalate (PET), a type of plastic. This is the same material used in making plastic bottles.
Thread Creation: PET is melted down and spun into threads. These threads are then woven or knitted into a fabric base.
Brushing the Fabric: To give fleece its signature softness, the fabric undergoes a brushing process. Tiny wire brushes fluff up the fibers, creating a texture that mimics wool while enhancing the fabric’s insulating properties.
Crude Oil → PET Plastic → Polyester Threads → Knitting/Weaving → Brushing → Fleece Fabric
Recycled Fleece: A Sustainable Twist
In recent years, manufacturers have turned to recycled polyester to create fleece with a lower environmental footprint. Instead of relying on new petroleum, recycled fleece repurposes materials like discarded plastic bottles. The process involves:
Collecting and cleaning plastic waste.
Melting the plastic into pellets.
Spinning the pellets into polyester threads, which are then transformed into fleece.
Plastic Waste → Cleaning & Melting → Polyester Threads → Fabric → Fleece
Why Brushed Polyester Stands Out
The brushing technique not only makes fleece incredibly soft but also traps air between the fibers. This trapped air boosts the fabric's insulating properties, keeping you warm in colder temperatures. It’s one reason fleece remains a favorite for outdoor gear and activewear.
The Hidden Cost of Fleece Production
While fleece is affordable and easy to produce, its reliance on fossil fuels and the energy-intensive manufacturing process raise concerns. Even recycled fleece, though a step in the right direction, requires significant resources to process plastic into wearable fabric.
Understanding how fleece is made allows us to appreciate both its ingenuity and its environmental impact. By choosing options like recycled fleece or wearing it responsibly, we can reduce its footprint and still enjoy its cozy benefits.
Environmental Impact of Fleece
Fleece may be soft and versatile, but its environmental impact is anything but gentle. Understanding the hidden costs of this popular fabric is essential for anyone striving to live sustainably. Let’s dive into the key environmental issues tied to fleece and why it’s worth reconsidering its role in your wardrobe.
The Fossil Fuel Connection
Fleece is primarily made from polyester, a synthetic fiber derived from petroleum. The production of virgin polyester not only relies heavily on fossil fuels but also emits significant amounts of greenhouse gases. This makes the manufacturing process energy-intensive and a contributor to climate change. While recycled fleece—often made from plastic bottles—offers a slightly greener option, it still ties the fabric to the petrochemical industry.
The Microplastic Problem
One of the most concerning impacts of fleece lies in the tiny, nearly invisible microplastics it sheds. Every time you wash a fleece garment, small fibers break off and flow into wastewater systems. These microplastics are difficult to filter out, eventually making their way into rivers, oceans, and even the food chain. Scientists have found microplastics in marine life, drinking water, and even human blood, raising serious ecological and health concerns.
Durability Meets Waste
Fleece is celebrated for its durability, but this longevity comes with a downside: it’s not biodegradable. Once disposed of, fleece garments can persist in landfills for centuries, contributing to the growing problem of textile waste. This creates a paradox—while fleece lasts long enough for years of use, it also outlasts our lifetimes in the environment.
Water and Energy Use
Though fleece doesn’t require the extensive water resources that cotton does, its synthetic nature means that its production is energy-intensive. Moreover, the dyeing and finishing processes often involve harsh chemicals that can pollute waterways if not properly managed.
While fleece offers undeniable comfort and practicality, its environmental impact makes it a fabric worth reevaluating. However, the story doesn’t have to end there—sustainable practices and eco-friendly alternatives can help minimize fleece’s footprint. In the next section, we’ll explore how you can enjoy the benefits of fleece while supporting a greener planet.

This process gives plastic a second life, reducing reliance on virgin polyester and cutting down on landfill waste. Look for certifications like Global Recycled Standard (GRS) to ensure the fabric meets sustainability standards.
Plant-Based Fleece Alternatives Some companies are innovating with fleece-like fabrics derived from natural, renewable resources such as organic cotton or bamboo. These alternatives mimic the softness and warmth of fleece while being biodegradable and free from microplastics.
Blended Fleece Hybrid fabrics that combine recycled polyester with sustainable materials, like hemp or Tencel, offer a middle ground. They maintain the functionality of fleece while lowering the overall environmental impact.
Practical Ways to Reduce Fleece’s Environmental Impact
Even if you already own synthetic fleece, there are simple steps you can take to minimize its ecological footprint:
Use a Microfiber Filter When Washing Fleece garments shed microplastics during washing, which can end up in oceans and waterways. Invest in a microfiber filter, such as a Guppyfriend washing bag, or install a filter on your washing machine to capture these harmful particles.
Wash Less, Wash Smart Reduce washing frequency to limit microplastic release. When you do wash fleece, use cold water and a gentle cycle to minimize shedding.
Extend the Life of Your Fleece Repair holes, reinforce seams, and properly store your fleece garments to keep them in use for as long as possible. The longer you use an item, the smaller its environmental impact.
