REALLY wanted to like this one...
So i lusted for this jacket for quite a while. I wanted the Arc'teryx Atom LT but the price was too much - and I went w/ the Thermawrap BC after getting a deal. Plus, the orange is an awesome color and looks even better in person. I agree w/ the below reviewers on two main points: 1) the fit is not as advertised and 2) the stretchy material at the sleeves and sides degrades fairly quickly. I ended up sending this back and going with the Atom LT, as I should have done in the first place.
For reference, I am a lean 6'5", 190 lbs, and the Atom LT fits like a second skin.
