Quick answer: Polar fleece is usually polyester-based and is widely used for lightweight, quick-drying outdoor layers. Cotton fleece has a softer, more natural hand and is common in casual or lifestyle garments, but it generally absorbs more moisture and dries more slowly. The better choice depends on the product position, care needs and expected use.
| Factor | Polar fleece | Cotton fleece |
|---|---|---|
| Common fiber | Polyester | Cotton or cotton blend |
| Moisture behavior | Lower absorption and faster drying | More absorbent and usually slower drying |
| Typical use | Outdoor mid-layers and lightweight jackets | Casual jackets, sweatshirts and lifestyle pieces |
| Hand feel | Varies from smooth microfleece to high pile | Soft, familiar cotton-rich touch |
Polar fleece is a knitted fabric with a raised surface that traps air. It can be produced in different weights, pile heights and finishes. Outdoor brands often choose it for mid-layers because it offers useful warmth without the moisture absorption of cotton-rich fabrics.
Not all polar fleece performs the same. Density, yarn, knit structure, brushing and anti-pilling treatment can change the appearance and durability. Buyers should approve the actual fabric rather than specifying only “polar fleece.”
Cotton fleece is commonly a knitted fabric with a smooth face and a brushed or looped inside. Some fabrics are 100% cotton, while many use blends to improve stability, durability or cost. It feels familiar and works well for casual collections where comfort and natural touch are more important than fast drying.
Fiber name alone cannot answer this. Warmth depends on fabric weight, thickness, density, pile and garment design. A thicker cotton fleece may feel warmer than a light polar fleece, while a high-loft polar fleece may provide more insulation at a lower weight. Compare physical swatches and samples made to similar constructions.
Polar fleece is usually the more practical option for hiking, travel and outdoor layering because it is lighter for its bulk and dries faster. Cotton fleece may suit urban outdoor collections, casual workwear or products designed around a cotton-rich feel. For wet conditions, neither should be presented as a waterproof outer layer unless a separate protective construction is used.

Start with the customer and use case, then compare fabric swatches against target weight, touch, care and price. Produce a sample in the selected fabric before locking measurements because stretch and shrinkage can affect fit. The broader fleece jacket manufacturing guide explains the full development process.
RUINIU works with brands on custom fleece jackets, including material review, sampling, branding and bulk production. Send the intended use, design file or reference garment to discuss suitable options. Final cost, MOQ and lead time depend on the confirmed specification.
