Alpaca is a beautiful fibre because it is actually warmer than wool due to the structure of the fibre itself, it is hypoallergenic (no lanolin), is naturally water-repellant and has great breathability, whereas wool can suck in water which causes it to create discomfort against the skin. It also is a much softer fibre than wool. Wool can vary in its texture based on the quality (measured in microns) of wool being used for a piece, the smaller the microns the softer the wool. Often alpaca is directly compared to merino wool or cashmere. Alpaca also comes in 22 natural colours and can be dyed, and I have seen some extremely vibrant colours that are just incredible.
