In reply to fozmeister:
People will tell you Haglofs, though I don't find them long enough. Mammut made their pants in an extra long leg (size 104, 106 etc) but these are very hard to find, and expensive. Arcteryx are OK, but not really long enough for 36".
I have a few pairs from www.beyondclothing.com and they are excellent - best fitting pants ever. I have both the Cold Fusion pants (like Powershield) from the Classic range, and the Glacier Shock pants (Epic shell) and a lighter pair. Crap colour range, but unsurpassed fit, if you fill in the form right.
