This jacket has a trim fit, like the flex pants. There is room for a base and a mid layer - as you would expect for alpine climbing and hiking, but you won't easily wear much more than that underneath. Despite the trim fit, there is no binding or lifting when you move your arms around. I liked all the features, the material, and the clean design of this jacket, with one exception: the hood. It has a single elastic drawcord that cinches at the back. There is indeed room for a helmet, so much so that without a helmet on and try as I might, I could not find a way to properly adjust the hood, and the visor kept falling down over my eyes. This was a deal breaker for me, and I returned the jacket. Too bad. It really is a nice jacket.
