Nice jacket but sizes run small - Marmot Featherless Component Jacket - Men's

Nice jacket. Had all the features you’d expect from reputable name-brand product. I’m six foot, 245 pounds and take a 2X size for everything above my waist. It appeared the jacket was labeled 2X, but when I put it on, I could barely zipper it. It fit like a large or XL size....needless to say, it went back.
