I have tried a few Norrona technical shells (thanks to BC for outstanding return policy). Great quality stuff, but sizing is tricky. The chart for Norrona is generic and I think refers to body size. Actual garment dimensions vary quite a bit, presumably based on design/usage considerations. I am 6' 4", 195#. I compared the actual garments to see how they differed.
Lofoten is probably the best fit for me for skiing, with longer arms and body, and athletic fit; I liked how the XL fit, if they had any good colors left; L is a little too trim for insulation.
Falketind is the trimmest model I tried, very slim, and shorter in body. Falketind XL is quite a bit smaller than the Lofoten XL in body width and length, and also shorter sleeve length.
My favorite in terms of quality build is the Trollveggen (pro shell version). Best fabric, great zippers, designed for mountaineering. It's a technical fit, but Trollveggen L is wider than Lofoten L, almost exactly the same as Lofoten XL. The Trollveggen L is a good fit for me in the body, but I wouldn't mind the sleeves a touch longer. The front on the Trollveggen is short, designed for harness access, which may not be ideal for skiing. There is a long drop back hem.
I didn't compare to the soft shells or insulated models. I do own the Svalbard soft shell in XL, which is one of my all time favorite jackets for less intense ventures.
What would be great would be a Norrona garment measurement chart by model and size. I had one once from Arcteryx years ago, and it was interesting how different the specs were between models.
