Alpaca is a fibre, not a wool
Strictly speaking, wool is the fleece of a sheep. What grows on an alpaca is a fibre, closer in structure to hair than to fleece. The phrase "alpaca wool" has stuck because it is what people search for, and we use it for that reason. But the distinction is worth understanding, because it explains everything that follows.
Sheep's wool is coated in lanolin, a natural grease that has to be scoured out before spinning, and each strand is covered in overlapping scales. Those scales are what catch against the skin and cause the itch that has put so many people off knitwear. Alpaca fibre carries no lanolin and its scales are far smaller and lie flatter. The result is a strand that feels smooth rather than prickly, even in a close-fitting piece.
Why alpaca is warmer at a lighter weight
The core of an alpaca fibre is partly hollow. Those air pockets trap warmth against the body in the same way a down jacket does, without any of the bulk. Weight for weight, alpaca holds heat more effectively than sheep's wool, which is why an alpaca wrap can feel almost weightless across the shoulders and still be warm enough for a cold evening.
The same structure lets the fibre breathe. When you step from outside into a heated room, alpaca releases warmth rather than holding it, so you rarely find yourself too hot in it. Wool tends to insulate whether or not you want it to.
Softness, and how it compares to cashmere
Alpaca is often compared with cashmere, and the comparison is fair. The finest grades of alpaca sit in the same range as cashmere for fineness and feel very similar against the skin. Where alpaca differs is in strength. The fibre is longer and more resilient, which means it pills far less, keeps its shape longer and lasts for decades rather than seasons.
Why it rarely needs washing
Alpaca does not absorb odour or moisture the way wool and synthetics do. It wicks, breathes and self-regulates, so a wrap or jumper worn for weeks can be shaken out, aired and put back on. Most of our customers wash a piece once a year, if that. A full guide to caring for alpaca is here: Alpaca Apparel Care Guide
What "alpaca clothing" should mean
Not everything sold as alpaca is what it claims to be. Much of the market blends a small proportion of alpaca with acrylic or nylon to lower the cost and firm up the knit. It will not feel, breathe or last the same way.
Every piece we make is pure alpaca from our own herd in the New Forest. The fleece is scoured and spun at Two Rivers Mill, a small family-run mill, and knitted in Leicester by makers we know by name. Each piece can be traced back to the field it came from. From the alpaca to the apparel, nothing is hidden.
Where to begin
If you want to feel the difference for yourself, the wrap is where most people start: https://alpacaapparel.co.uk/collections/alpaca-capes It is the piece that made us, and it remains the one our customers reach for first.
Frequently asked questions
Is alpaca warmer than wool?
Weight for weight, yes. The hollow structure of the fibre traps warmth without bulk, which is why alpaca feels light on the shoulders and warm on the skin.
Can I wear alpaca if wool makes me itch?
Almost always. The prickle in wool comes from coarse, scaled fibres and lanolin. Alpaca has neither, and most people who react to wool wear it without any trouble.
Why do you still call it alpaca wool?
Because that's what most people search for. Technically it's a fibre rather than a wool, and we'd rather you know the difference than be sold on the wrong word.
