This is one of our warmest jackets. It's made of 12-ounce 100% cotton sandstone duck that's lined with arctic-weight quilted nylon polyester -- which is just about as warm as it gets. The contrasting corduroy collar has under collar snaps for an optional hood. There are two convenient inside pockets and two deep hand-warmer-style side pockets. Rib knit cuffs also work keep you warm. And a split-back with bi-swing and pleated elbows allows for easier movement on-the-job.
