What Is Fleece Fabric? Meaning, Types, Uses & Benefits
Fleece fabric is one of the most widely used insulating textiles in modern apparel, but most buyers know it better by feel than by composition. That soft, brushed surface that traps warmth without adding bulk is the result of a specific manufacturing process applied to knitted polyester fibres.
Most fleece available today is made from polyester, specifically PET (polyethylene terephthalate), the same material used in plastic bottles. The sustainable alternative, rPET or recycled polyester fleece, is made from post-consumer plastic waste processed at GRS-certified recycling facilities and carries approximately 50% lower carbon footprint than virgin polyester equivalent.
How Fleece Fabric Is Made?
Polyester fibres are knitted into a base fabric, then passed through a brushing machine that lifts the fibres and forms tiny air pockets across the surface. Those air pockets trap body heat, which is what makes fleece warm at low weight. Anti-pill treatment is applied afterward to reduce surface bobbling through repeated washing.
Key Properties of Fleece Fabric
Fleece delivers a combination of properties few other fabrics match at the same weight. The knit construction gives it natural stretch, and GSM (grams per square metre) determines its warmth level. Fleece below 200 GSM is microfleece for layering; 300 GSM and above is heavyweight polar fleece for outer insulation.
The core properties that define fleece fabric across all weight categories:
- Thermal insulation: the brushed pile traps air between fibres, maintaining warmth without adding bulk.
- Moisture management: polyester fleece moves moisture through the fabric rather than holding it against the skin, keeping the wearer more comfortable during physical activity.
- Quick drying: fleece dries significantly faster than cotton or wool after washing or rain exposure.
- Softness: the napped surface makes fleece one of the softer synthetics for skin contact, which is why it is common in children's garments and base layers.

Advantages of Fleece Fabric
Fleece holds consistent commercial appeal because it delivers warmth, durability, and ease of care at a price point that natural fibres cannot match at scale. For brands building winter collections or activewear ranges, these practical advantages are the primary driver of sourcing decisions.
The main advantages that make fleece fabric a preferred choice in apparel manufacturing:
- Lightweight insulation: fleece provides warmth comparable to heavier wool weights at a fraction of the mass, making it suitable for garments worn across a full day without fatigue.
- Machine washable and low-maintenance: unlike wool or down, fleece does not require special washing conditions. It holds its shape and pile through repeated machine wash cycles.
- Affordability at scale: polyester fleece is one of the most cost-efficient insulating fabrics available, with rPET options now available at comparable price points to virgin polyester from certified suppliers.
- Colourfast and printable: polyester accepts dye with high colour retention, and printed fleece holds pattern definition well across the fabric's usable life.
Organic Cotton Knit Fabric and Bamboo Knit Fabric carry the same softness advantage for lighter-weight knitwear where natural fibre breathability and skin comfort are the specification priority.
Types of Fleece Fabric
The fleece category covers several distinct constructions, each with different weight, texture, and performance properties. The right type depends on the end use, the required warmth level, and the garment construction.
Polar Fleece
The most common commercial fleece, typically 200 to 350 GSM. Polar fleece is mid-to-heavyweight, with a dense pile on both sides and strong insulation for its weight. Used in jackets, pullovers, blankets, and workwear. The pile is uniform and smooth, which allows garment construction and printing to work cleanly.
Sherpa Fleece
A high-pile fleece with a looped surface that mimics shearling, used primarily as lining in jackets, coats, and footwear. Sherpa adds significant warmth to any construction it lines.
Anti-Pill Fleece
A surface-treated fleece where fibres are processed to resist pilling during washing. Anti-pill treatment extends garment lifespan and is the standard specification for uniform programmes and children's wear.
Merino Wool Fabric delivers comparable insulation to polar fleece at similar weights and retains warmth in wet conditions where polyester performance declines. 100% Natural Hemp Fabric builds structural body into outerwear constructions and handles repeated laundering without synthetic content.

Common Uses of Fleece Fabric
Fleece is commercially versatile because its warmth-to-weight ratio and easy construction suit a wide range of product categories. GSM determines which weight is appropriate for each application.
Common end uses by category:
- Outerwear and mid-layers: polar fleece and sherpa are the standard for winter jackets, vests, and hooded pullovers.
- Base layers and activewear: microfleece is the preferred construction for next-to-skin performance layers, particularly in cold-weather sport and outdoor activity.
- Home textiles: fleece is widely used in blankets, throws, and cushion covers where softness and washability are the primary requirements.
- Children's apparel: the soft pile, easy care, and anti-pill variants make fleece the standard fabric for children's sleepwear, outerwear, and casual layers. Children's base layers in Bamboo Cotton Handloom Fabric combine the soft handle of bamboo with the breathability of natural cotton construction.
