Meta Description: What kind of fabric is fleece? Learn everything about fleece fabric, from its origins and types to uses, pros, cons, and care instructions in this comprehensive guide.

Introduction to Fleece Fabric

Fleece is one of the most beloved fabrics in the world of textiles. Known for being incredibly soft, lightweight, and warm, it has become a staple in outdoor clothing, blankets, and loungewear. But what kind of fabric is fleece exactly? This guide explores everything you need to know about fleece—its history, how it's made, the different types, its pros and cons, and how to care for it properly.

History and Evolution of Fleece

Fleece as we know it today was first developed in the late 1970s by Malden Mills (now Polartec). It was a revolutionary synthetic alternative to wool—lighter, more breathable, and easier to care for.

Originally marketed under the name PolarFleece, it quickly gained popularity for use in activewear and cold-weather gear. Over the decades, fleece has evolved in texture, thickness, and function, with multiple subtypes available in today’s textile market.

How is Fleece Made?

Raw Materials Used

Fleece is primarily made from polyester, a synthetic fiber derived from petroleum. Sometimes it’s blended with natural fibers like cotton or wool to improve feel or breathability.

Recycled fleece, made from post-consumer plastics like PET bottles, has also gained traction as a sustainable alternative.

The Manufacturing Process

1. Polyester chips are melted and extruded into fibers.

2. These fibers are spun into yarns.

3. The yarns are knitted into fabric sheets.

4. The fabric is brushed on one or both sides to create a fluffy nap that traps air—enhancing insulation.

5. Additional finishes (anti-pill, water-repellent) may be applied.

Types of Fleece Fabrics

Fleece isn’t one-size-fits-all. Here's a breakdown of the most common types:

Polar Fleece

• Medium to heavy weight

• Soft on both sides

• Ideal for jackets and winter gear

Microfleece

• Lightweight and breathable

• Great for layering

• Often used in athletic wear

Sherpa Fleece

• Has a wool-like appearance

• Fluffy and thick

• Common in linings and cozy wear

Coral Fleece

Characteristics of Fleece Fabric

Texture and Feel

Fleece is ultra-soft, cozy, and plush to the touch. It’s designed to imitate the feel of natural wool without the itchiness.

Weight and Warmth

Even lightweight fleece traps body heat effectively. Its insulation power increases with fabric thickness.

Moisture-Wicking Ability

Unlike cotton, fleece doesn’t absorb moisture. It wicks sweat away, making it ideal for outdoor and athletic use.

• Avoid fabric softeners (they reduce wicking ability)

• Use a mild detergent

Drying and Storing

• Air dry or tumble dry on low

• Don’t iron fleece

• Store in a dry, cool place away from sunlight

Buying Guide: Choosing the Right Fleece

When selecting fleece, consider:

• Use case (outdoor, casual, bedding)

• Weight (lightweight for layering, heavyweight for outerwear)

• Finish (anti-pill for longevity)

• Material (recycled vs virgin polyester)
