“At Pendleton Woolen Mills, Clarence Morton Bishop envisioned a different kind of fabric for a man’s wool shirt. Pendleton’s sophisticated weaving capabilities were producing vibrant Indian trade blankets. Why not bring that same weaving and color know-how to flannel shirting?  After much weaving experimentation and hard work, Pendleton’s innovative Umatilla shirting fabric rolled off the loom. The positive response was immediate. After World War II, the concept of sportswear emerged in American society.  While hunting, fishing, or pursuing his hobbies, Dad very often wore a Pendleton shirt.  Throughout the 20th century, clothing trends have emerged from workwear and traveled into the fashion mainstream. Casual and colorful, leisurewear symbolized the end of privation and the return of the good life.”
