"Natural vs synthetic" sounds like a simple question, but it covers a lot of ground: what each term actually means, whether a specific fibre like wool, cotton, nylon or polyester counts as one or the other, and which one wins for comfort, durability and the environment. Here's a clear answer to each of those questions — including how genuine sheepskin fits into the picture.

What Are Natural Materials?
A natural material is a fibre that comes directly from a plant or animal source, with no synthetic chemical process used to create the fibre itself. Common natural fibres include:
- Wool — from the fleece of sheep (or goats, for cashmere). Naturally elastic, breathable, and good at regulating body temperature.
- Cotton — from the cotton plant's seed pods. Soft, breathable, and highly absorbent.
- Linen — from the flax plant. Cool, breathable, and stronger than cotton, though it creases easily.
- Silk — from the cocoons of silkworms. Lightweight, smooth, and naturally hypoallergenic.
- Leather — made from tanned animal hides. Durable, flexible, and a good insulator.
- Hemp — from the hemp plant. Strong, UV-resistant, and softens with use.
Key takeaway: a few fibres marketed as "natural," like bamboo viscose, are grown naturally but require heavy chemical processing to turn the plant into fabric — that makes them more accurately "semi-synthetic" or "regenerated cellulose" fibres rather than fully natural ones, which is worth knowing if biodegradability matters to you.
What Are Synthetic Materials?
A synthetic material is a fibre manufactured through a chemical process, typically from petrochemicals or petroleum byproducts, rather than grown or harvested. The most common synthetic fibres are:
- Polyester — the most widely used synthetic fibre worldwide. Wrinkle-resistant, quick-drying, and inexpensive to produce.
- Nylon — strong and elastic, often used in activewear, hosiery, and outdoor gear.
- Acrylic — designed to mimic wool's warmth and softness at a lower cost.
- Spandex (elastane) — highly stretchy, almost always blended with other fibres rather than used alone.
Synthetic fibres are generally resistant to wrinkles, shrinking, and staining, but they don't breathe or absorb moisture the way natural fibres do, and most are not biodegradable.
Natural vs Synthetic: The Core Differences
Here's how the two categories compare across the factors that matter most day to day:
Is Wool Natural or Synthetic?
Wool is 100% natural. It's a protein fibre (keratin) grown in the fleece of sheep, shorn and spun into yarn with no synthetic chemical process involved in creating the fibre itself. That's what gives wool its natural moisture-wicking and temperature-regulating properties, and why it's also naturally flame-resistant — wool tends to self-extinguish rather than melt or continue burning, unlike most synthetics.
Is Cotton Natural or Synthetic?
Cotton is also fully natural — a plant fibre harvested from the seed pods of the cotton plant. It's soft, breathable, and highly absorbent, though unlike wool it doesn't insulate well when wet.
Is Nylon Natural or Synthetic?
Nylon is entirely synthetic. It was the first fully synthetic fibre, developed in the 1930s from petrochemicals, and there's no natural or plant-based version of it. It's valued for being strong, elastic, and quick-drying, which is why it's common in hosiery, activewear, and outdoor gear.
Is Polyester Natural or Synthetic?
Polyester is synthetic. It's made from petroleum-derived polymers (most commonly PET, the same polymer used in plastic bottles), spun into fibre. It's the most widely produced fibre in the world today because it's cheap, wrinkle-resistant, and holds colour well — but it isn't biodegradable and sheds microplastics when washed.
Advantages and Disadvantages of Synthetic Materials
Synthetic materials aren't without merit — they're just suited to different jobs than natural fibres:
- Advantages: lower cost, resistant to wrinkles and shrinking, quick-drying, and often more water-resistant — useful for sportswear, outerwear, and budget-friendly textiles.
- Disadvantages: less breathable, can trap heat and odour, non-biodegradable, and shed microplastics into waterways during washing. They're also harder to recycle than most people assume, often requiring manual separation or chemical processing.
Why Natural Fibres Like Wool Still Win for Comfort and Sustainability
For anything worn against the skin or used for warmth — clothing, rugs, bedding — natural fibres generally outperform synthetics on comfort. Wool and cotton are more breathable, better at regulating temperature, and gentler on sensitive skin, since they don't trap moisture and heat the way synthetics can.
Key takeaway: natural fibres are also biodegradable and require less energy-intensive processing than synthetics, and when they're produced through ethical farming and tanning practices, they support a lower overall environmental footprint from production through disposal.
How to Tell If Sheepskin Is Genuine or Synthetic
Sheepskin is one of the most commonly faked natural materials — "faux sheepskin" is usually a synthetic acrylic or polyester pile knitted onto a woven fabric backing. Here's what sets the real thing apart:
- The backing. Genuine sheepskin has a suede or leather backing (the tanned hide itself), not a woven or knitted fabric. On twin-faced sheepskin used for footwear, that backing is finished and dyed to look intentional; on faux versions, you'll find fabric or netting instead.
- The wool. Real sheepskin wool grows in individual, slightly irregular fibres rather than a perfectly uniform machine-made pile, and it springs back into shape after being pressed down. Synthetic pile tends to mat down and stay flattened.
- The feel and warmth. Genuine wool insulates in winter and stays breathable in summer; synthetic fill tends to feel warm and static-prone rather than naturally temperature-regulating.
Every product across our sheepskin rugs, sheepskin boots, and sheepskin slippers collections is made from genuine tanned sheepskin, not a synthetic substitute. Our sheepskin types guide goes further into the different types of genuine sheepskin we use and what each is suited for.
FAQ: Natural vs Synthetic Materials
What does "synthetic material" mean?
A synthetic material is a fibre manufactured through a chemical process, usually from petrochemicals, rather than grown or harvested from a plant or animal. Polyester, nylon, and acrylic are all synthetic.
What's the main difference between natural and synthetic materials?
Natural materials are grown or harvested and generally biodegrade, while synthetic materials are manufactured from chemical processes and generally don't. That difference carries through to breathability, durability, and environmental impact.
Are there similarities between natural and synthetic fibres?
Yes — both can be spun into yarn and woven or knitted the same way, both come in a wide range of weights and finishes, and manufacturers often blend the two (like cotton-polyester blends) to combine natural comfort with synthetic durability.
Can natural and synthetic fibres be combined?
Yes, blended fabrics are common — for example, wool-nylon blends for added strength, or cotton-spandex blends for stretch. The blend ratio determines which fibre's properties dominate.
Is faux sheepskin the same as synthetic sheepskin?
Yes — "faux sheepskin" and "synthetic sheepskin" both describe the same thing: an imitation made from synthetic fibres like acrylic or polyester rather than a genuine tanned sheep's pelt.
Conclusion
Natural materials like wool and cotton are grown or harvested and generally win on breathability, comfort, and biodegradability; synthetic materials like nylon and polyester are manufactured from petrochemicals and win on cost, wrinkle-resistance, and durability under hard wear. For anything meant to be worn, sat on, or slept under, that's usually a case for the natural fibre — and if you're choosing sheepskin specifically, browse our genuine sheepskin collection to see the real thing for yourself.
