I picked this beauty up at a Filson direct to customer Warehouse sale as a gift but never gave it, so it's got to go. made from filson's thickest and warmest Mackinac wool it is a timeless and durable classic that has function beyond compare. this one has never been worn still has its tags on but does have the strike through on the label indicating it was sold at a warehouse sale. I estimate this piece to be from the late 80s or early '90s but I'm not sure. note that it is designed as a liner so it has a button on the back collar to connect it to Filson jackets that take a liner. Also notice the very nice touch of the metal cinch cords at the waist to draw it in tight and keep out the cold air.
