Fiber Guide: Alpaca, Merino, Mohair, Cashmere, Linen & Cotton Compared

Choosing the right textile for your home comes down to understanding how each fiber feels, performs, and fits your lifestyle. Whether you're searching for a weightless summer throw or a deeply warming winter blanket, this guide will help you find the fiber that's right for you.

A note on fiber properties: natural fibers vary by breed, origin, and processing, so the qualities below reflect general characteristics rather than universal standards. Your experience may vary — and that's part of what makes natural textiles so beautifully individual.

Alpaca

Warmth: Alpaca fibers have a naturally hollow core that traps heat exceptionally well, making alpaca one of the warmest natural fibers you can choose. Many people find it warmer than sheep's wool of a similar weight.

Weight: Remarkably light for its warmth — alpaca throws and blankets tend to feel airy rather than heavy.

Breathability: Moderate. The hollow fiber helps regulate temperature reasonably well, though it shines most in cooler conditions.

Softness: Fine alpaca (especially baby alpaca grades) is notably soft and often described as gentle against sensitive skin.

Care: Best handled with care — hand washing in cool water or a delicate machine cycle, then laying flat to dry. Avoid heat and agitation.

Ideal for: Autumn and winter use; layering on sofas and armchairs; a cosy companion for cooler bedrooms.

Merino Wool

Warmth: Merino is a genuinely warm fiber that also breathes, making it one of the most versatile options across seasons.

Weight: Medium — merino weaves and knits have a satisfying drape and body without feeling overly heavy.

Breathability: One of merino's most celebrated qualities. The fiber actively manages moisture and temperature, helping you feel comfortable whether the room is cool or warm.

Softness: Much finer than standard wool, merino is soft enough that most people find it comfortable directly against the skin.

Care: Many merino pieces are machine-washable on a wool or delicate cycle — always check the care label. Reshape and dry flat.

Ideal for: Year-round use; bedrooms and living rooms; anyone who wants warmth without weight and a fiber that works across seasons.

Mohair

Warmth: Mohair is warm and insulating, with a natural loft that traps air effectively.

Weight: Light to medium, with a characteristic fluffiness that gives pieces a generous, cloud-like feel.

Breathability: Good — mohair tends to regulate temperature reasonably well and is less prone to feeling stuffy than heavier wools.

Softness: Mohair has a distinctive silky sheen and smooth texture. Fine-grade mohair (particularly kid mohair) is especially soft; coarser grades can feel ticklish to sensitive skin.

Care: Gentle hand washing is recommended. Avoid wringing or excessive heat. Lay flat to dry to preserve the fiber's natural loft.

Ideal for: Autumn and winter; adding texture and warmth to a living space; statement throws with a luxurious feel.

Cashmere

Warmth: Cashmere offers impressive warmth for its weight — a relatively thin cashmere throw can feel surprisingly cosy.

Weight: Among the lightest of the warm natural fibers, which contributes to its reputation as a luxury choice.

Breathability: Moderate to good. Cashmere breathes better than many synthetic alternatives and works well in layered styling.

Softness: Cashmere is widely regarded as one of the softest natural fibers available. The finest grades are exceptionally gentle and smooth.

Care: Requires gentle handling — hand washing in cool water with a mild detergent, or dry cleaning. Lay flat to dry and store folded, not hung, to prevent stretching.

Ideal for: A considered, lasting investment; cool living rooms and bedrooms; gifting to someone who appreciates true quality.

Linen

Warmth: Linen is not a warm fiber — and that's entirely the point. It excels at keeping you cool and comfortable in warmer conditions.

Weight: Light to medium, with a relaxed drape that improves beautifully with each wash.

Breathability: Outstanding. Linen is one of the most breathable natural textiles and is particularly well-suited to warm, humid conditions.

Softness: Linen softens noticeably over time and with use. It starts with a pleasantly crisp texture and becomes increasingly soft and supple through washing and wear.

Care: Generally easy to care for — machine washable in most cases, and it becomes softer with each wash. Avoid high heat to reduce shrinkage.

Ideal for: Spring and summer; warm bedrooms; layering for year-round use in temperate climates.

Cotton

Warmth: Cotton is a neutral-warmth fiber — neither particularly insulating nor cooling on its own, though heavier cotton weaves can add a comforting weight.

Weight: Varies widely by weave and construction, from light muslin to substantial waffle knits and chunky wovens.

Breathability: Good — cotton absorbs moisture well and feels fresh against the skin, making it a year-round favourite.

Softness: Cotton softness depends greatly on the quality of the fiber and weave. Long-staple cottons (such as Egyptian or Pima) tend to be noticeably softer and more durable.

Care: One of the easiest natural fibers to care for — typically machine washable and tumble-dryer friendly. Check the care label for specific guidance.

Ideal for: Everyday use across all seasons; family homes; anyone who wants effortless care alongside natural quality.
