I travel for a living and this is the ideal shell for walking around the cool, soggy cities of Europe. With an undershirt, collared shirt and then this shell and a hat (+ pants of course), you are ready to walk without having a bulky jacket to worry about. It's very lightweight and takes up literally no room in a suitcase. So good, I own two and will be ordering another after I finish this review.The negative reviewers obviously didn't understand the purpose of a lightweight shell. It's a complimentary and completing garment, not a solution by itself.
