This is one of the finest shells out there. It's cut roomy for layering. For me, in size small, a little too roomy; it would benefit from a drawcord adjustment in the torso, or just a slimmer cut. As with all Marmot gear the materials and workmanship are excellent. Great hood, Gore Tex Pro Shell is very nice; I like it better than XPR, but only because it's lighter, and this is a light shell. XPR is denser and tougher. The great thing about the Troll Wall is that it's usable for various activities; not just climbing. I have an Arc'Teryx Alpha SV (XPR), and it's ultra tough; great for climbing, but not much else. The Troll Wall will no doubt do it all; the removable snow skirt is a big plus. It's just a great piece of gear. But I am a Marmot freak; their stuff (all of it I've ever had) works for me. The extreme cold weather stuff (CWM bag and 8000m set) has saved my life more than once. But back to the subject. The Troll Wall shell is great; worth the price. You will not be disappointed.
