Hands down, the best winter shell I've ever had. And I'm something of a jacket junkie.Like a bomb shelter at the top of the mountain, windchills of 50 below didn't stand a chance. And when you're flying down or working hard, unzip the vents to stay comfortable - it vents like a champ (as opposed to others that seem to be more about show than function). Pockets are everywhere you want them with sealed zippers, so nothing gets in, and the large zipper pulls are mitten-friendly. The soft-shell fabric moves with you as advertised, a huge benefit over traditional hard shells.True to size: 5'8", 145lb, size medium. It fits a little big over just a fleece, but pairs perfectly with a puffy for wicked cold days on the mountain. It runs a little long on my short torso, but that's nothing to get excited about in an otherwise PERFECT jacket.
