How does alpaca fiber perform for outdoor clothing?

Alpaca fiber is a high-performance natural material that rivals merino wool in many outdoor applications. It is hollow, making it exceptionally warm relative to its weight, with thermal properties that exceed sheep's wool by a significant margin. Alpaca is also naturally water-resistant, with a smooth fiber surface that causes water to bead rather than absorb. Unlike merino, alpaca contains no lanolin, making it naturally hypoallergenic.

Alpaca fiber is stronger than merino wool and more resistant to pilling, giving garments longer life. It is lightweight, soft, and available in a natural range of colors that require no dyeing. The fiber's hollow structure also provides natural insulation that works in both cold and mild temperatures by regulating heat exchange.

Brands like Paka and Arms of Andes specialize in alpaca activewear and outdoor layers that demonstrate the fiber's versatility. Their products perform in demanding conditions without any synthetic fiber, PFAS treatment, or chemical finish. ONDU features these brands because alpaca is a compelling example of how natural fibers can exceed synthetic performance while being fully biodegradable.
