If you don't currently own any alpaca, chances are you've never felt anything this soft. It's spun from 100% baby alpaca, humanely-shorn each spring from the underside of the animal's neck and body (where the fiber is the softest and finest at an insane 22.5 microns). So why alpaca? It's as soft as cashmere, but 7x warmer than wool, not to mention breathable, stain and odor-resistant, eco-friendly, and durable as hell. With a flash-tat-looking rattlesnake motif, it's soft to the touch, but bad to the bone.
