Content
Flannel is a woven fabric—traditionally made from cotton or wool—that gets its signature softness from a brushing process that raises tiny fibers off the surface, while fleece is a knit synthetic fabric (usually polyester) that achieves softness through its knit structure and pile, and standard cotton is a plain-woven fabric with no brushing at all, resulting in a smoother, crisper hand-feel. The core distinction is this: flannel and cotton are both woven fabrics that differ mainly in finishing (brushed vs. unbrushed), while fleece is a fundamentally different knit construction—meaning flannel actually has more in common structurally with plain cotton than it does with fleece, despite feeling similarly cozy.
How Flannel Fabric Is Made
Flannel Fabric starts as a standard woven fabric—typically a plain or twill weave—made from cotton, wool, or a cotton-synthetic blend. What makes it "flannel" is a mechanical brushing process applied to one or both sides of the fabric, which uses fine wire brushes to gently pull individual fibers up from the weave, creating the soft, slightly fuzzy nap flannel is known for.
Weight and Quality Indicators
Flannel quality is typically measured in grams per square meter (GSM). Lightweight flannel starts around 110 GSM and is common in warm-weather shirts, while heavyweight flannel used for bedding or outerwear often ranges from 170 to 200+ GSM, offering noticeably more warmth and durability.
Single-Nap vs. Double-Nap
Single-nap flannel is brushed on only one side, while double-nap flannel is brushed on both sides, making it noticeably softer and warmer—double-nap is the standard for premium flannel shirts and sheets.
How Fleece Fabric Is Made
Fleece is a knit fabric, almost always made from polyester (or a poly-cotton blend), constructed by knitting fine synthetic fibers into loops and then brushing the surface to create a raised pile—similar in concept to flannel's brushing but starting from a completely different base structure.
Why the Knit Structure Matters
Because fleece is knit rather than woven, it has natural stretch and traps air more effectively within its looped fiber structure, giving it a higher warmth-to-weight ratio than most woven fabrics, including flannel. This is why fleece jackets often feel warmer than a flannel shirt of similar thickness.
Common Fleece Weights
- Microfleece (100-weight) – lightweight, used for base layers
- Mid-weight fleece (200-weight) – general-purpose jackets and pullovers
- Heavyweight fleece (300-weight) – outerwear for cold climates
How Standard Cotton Fabric Is Made
Standard cotton fabric (like poplin or standard shirting cotton) uses the same basic weaving process as flannel but skips the brushing step entirely, leaving the surface smooth and the weave pattern clearly visible. This makes cotton lighter, cooler, and more breathable than flannel, but also less insulating in cold conditions.
Why It Feels Different from Flannel
Without brushed fibers trapping air near the skin, plain cotton relies solely on the weave's natural breathability, which is why it's favored for warm-weather clothing and bedding rather than winter layers.
Side-by-Side Comparison
Here's how the three fabrics stack up across the factors that matter most for everyday use.
| Factor | Flannel | Fleece | Cotton |
|---|---|---|---|
| Construction | Woven, brushed | Knit, brushed | Woven, unbrushed |
| Common Fiber | Cotton, wool | Polyester | Cotton |
| Warmth | Moderate–High | High | Low |
| Breathability | Moderate | Low–Moderate | High |
| Stretch | Minimal | Moderate | Minimal |
| Moisture-Wicking | Low | Moderate–High | Moderate |
Durability and Care Differences
Fleece generally resists pilling and shrinking better than flannel because synthetic fibers don't absorb moisture or shrink with heat the way natural cotton fibers do, but flannel tends to soften and improve with age rather than degrade, while fleece can flatten and lose loft after repeated washing.
Washing Flannel
Wash flannel in cold or warm water and avoid high heat drying, which can cause shrinkage and accelerate pilling on the brushed surface over time.
Washing Fleece
Wash fleece in cold water and avoid fabric softener, which coats synthetic fibers and reduces their moisture-wicking properties over repeated washes.
Washing Cotton
Standard cotton is the most forgiving of the three, tolerating machine washing and moderate heat drying without significant risk of pilling, though it can still shrink if not pre-treated (sanforized) by the manufacturer.
Best Uses for Each Fabric
Because each fabric has different strengths, the best choice depends heavily on the specific application.
- Flannel – Best for bedding, pajamas, and button-up shirts where a soft, breathable warmth is desired without bulk.
- Fleece – Best for outerwear, jackets, and blankets where maximum warmth-to-weight ratio and moisture resistance are priorities.
- Cotton – Best for warm-weather shirts, bedding, and everyday apparel where breathability and a crisp finish matter most.
Which One Should You Choose?
If you want a fabric that's soft, breathable, and gets better with age—for pajamas, shirts, or sheets—flannel is the better choice. If you need maximum warmth and moisture resistance for outdoor or active use, fleece wins. And if breathability and a lightweight, crisp feel matter most for warm-weather wear, standard cotton is the right pick. Many people actually own all three, using each for the season and application it's best suited for rather than treating them as interchangeable.
