Tourmaster stuff also seems to work well for we men of dimension.
Both can be had for very reasonable sums from Newenough.com (I refuse to use their stupid new generic name) clearances. They also gave a "hard to fit" section with good advice. Get on their email list and wait.
I have a pair of Aerostich Darien pants that I had custom-made with a slightly shorter thigh section. This moves the knee armor up to the vicinity of my knees instead of resting against my shins. The total was almost $400, but worth it because it solved a longstanding problem. Apparently I have strange knees...
