I inherited a FiveBrother heavy flannel from my Great-Uncle, when he passed away 9 years ago. I don't know how long he had it but I wear it almost daily throughout the winter. It's thick enough to be damn near windproof yet comfortable enough to lounge about the house in. On top of that, the snap up buttons have held up to over a decade of being ripped open Hulk Hogan style, with no hint of wear to the fabric or buttons.
