Made from a breathable cotton blend it has an amazingly soft fleeced interior to keep you toasty. There's no need to worry about it shrinking either. It's garment washed so it will keep its size even after you wash and dry it. No more warping zippers and short cuffs! Incredible. The fabric is substantial and durable as well so you'll get plenty of mileage out of it. The classic cut is flattering on every build and the zipper means it's easy to take on and off.
