Toasty warm and dry
I am 170 cm and 75 kg, with a slim but athletic build, and I usually wear just a shirt or a thinner crew neck sweater underneath my coats. On a recent trip to Chicago, I was on the open top deck of an architectural boat tour on the Chicago river where I experienced some chilly <5C temperatures, with wind and rain. And all the while, this jacket kept me toasty warm and dry! The small was perfectly sized; the medium was huge. I felt snug and the jacket looked well-fitted, but not puffy. Next stop: Reykjavik!
