What did the earliest Americans wear to survive brutal Ice Age winters? For decades, scientists could only guess. Clothing made from animal hides and plant fibers almost never survives millennia of decomposition. Now, two tiny scraps of elk hide from an Oregon cave are rewriting that story.

The fragments, joined by a cord of twisted fibers and preserved for roughly 12,400 years, appear to be the oldest sewn items ever discovered. They may also represent the world’s oldest known pieces of clothing, according to research posted to Science Advances on February 4, 2026.

What makes this find so unusual

The discovery challenges a fundamental limitation in archaeology: organic materials rot. Leather, plant fibers, woven textiles—the soft technologies that defined daily life for ancient peoples—almost never survive in the archaeological record. Stone tools endure. Bone needles persist. The actual garments people wore? They vanish.

These fragments beat those odds through a combination of geography and climate. Cougar Mountain Cave sits in Oregon’s high desert, where ultradry air created ...
