The benefits
Alpacas evolved where days run warm and nights turn cold. Their semi-hollow fibers trap insulating air, helping you stay comfortable as the temperature changes.
Alpaca’s smoother scales give the fabric a soft feel against your skin. Comfort comes from the fiber’s structure.
Alpaca wool naturally resists odor. Air your layer between wears, then wash it when it needs cleaning. Less time doing laundry. More time outside.
