Before Karu, we spent years in the alpaca world, working alongside Peruvian artisans, testing fibers, and learning exactly what this material can do.
These socks aren’t a guess. They’re the product of relentless sourcing, refining, and pushing alpaca to its edge.
That’s what makes Karu different. We know this fiber inside out — and built the sock to prove it.
Alpacas evolved at 17,000 feet where temperatures swing from scorching to freezing in a day.
Their secret? Wool with hollow fibers.
Where cotton and synthetics are solid, alpaca fibers create microscopic air pockets that regulate temperature like built-in insulation.
