This jacket is great. I ordered it 3XL, because I have a big stomach. I have room to layer a sweater underneath. The material is 100 polyester, and single layer. It has a smooth texture, that will repel water. The material is light weight. You can roll it up, to carry it, until needed. The sleeves are gently elastic, and the zipper front is zippy! The collar is thin, and folds over easily.
