The “DAD” shirt, throw this on to go out and grab some firewood in the chilly autumn mornings. Here’s what the company says of this classic top. Gold mining was serious business, so the original Woolrich designers didn’t fool around when they created a shirt especially for 19th-century Alaskan prospectors. We’ve updated it a bit since then, with a washable wool-blend fabric plus snap-front placket, pockets, and cuffs. Still one of our heaviest, toughest shirts, it will keep you seriously warm even if you don’t have gold fever. Inner comfort collar liner. 80% wool/20% nylon. Imported. Machine wash, line dry.
