By Ewe Hoo Design. These unique hats are created by unraveling gently used sweaters and re-knitting the yarn into something entirely new. The result is a one-of-a-kind, hand-made garment that is built to last. Each hat is blended with all natural fibers such as cashmere, merino wool, and alpaca. Lined with made-in-the USA Polar Tech for extra warmth and comfort. Hand-wash, air dry. Made in Montana, USA.
