In reply to Bigbadbarry:
I'm 6'7" with a 34" waist, 36" inseam and 46" chest.
Haglofs fits well, Rab are usually long enough in the arms but baggy around the waist and tight across the back and shoulders. Mountain Equipment seem OK but variable, and have changed over time. Arcteryx are pretty good, but there are variations and they generally seem to fit less athletically than they used to.
I can't really fit with Berghaus stuff at all. Patagonia is almost always too short in the arms, tight across the shoulders and loose around the waist, though their lines vary, a bit. Montane has always been too short in the arms and tight across the back, though I haven't tried anything from them for a while.
Dynafit clothing is great, if you can find it, but you need the biggest sizes. They're very trim around the waist while still being wide enough in the shoulders. Pants are too short though.
I can't find any decent trousers, especially hard shells, that are long enough.
Soft-shell? Haglofs and Arcteryx make Long sizes but are hard to get, expensive and usually only 34" inseam anyway. Mammut used to make extra long versions of their softshell pants but they're impossible to find and were very expensive. I have a pair of Rab VapourRise pants size XL that are quite long, but baggy and not good for many things.
EddieBauer/First Ascent in the US ( can order online) do plenty of Long sizes and I have some light soft-shell pants of theirs that are good, plus two jackets ( a shell and a Primaloft belay jacket) through their recent models are not as good.
