Nicolas Louis/Courtesy of A.P.CA.P.C. Raised at high altitudes of 4,000+ meters above sea-level, in the freezing and inhospitable Andes Mountain range of Peru, these fibers have developed microscopic air pockets that act like natural thermal insulators, making this accessory lightweight while also retaining body heat for supreme warmth.

The fibers have evolved micro-pockets that help with insularity.
