Yeah, I've got an Olympia jacket in either 3XL or 4XL that I really like. It fits well and is a high quality piece of gear. I believe it's a Moab. Olympia can be hard though because various jackets seem to fit differently even in the same sizes. Nice stuff though.
I also have a bunch of Tourmaster gear that is very roomy for bigger guys. I've got a Sonora and a Transition and a pair of their mesh pants and they all fit really well. The sizing is pretty consistent too so once you find your size you are good. The quality isn't as high as Olympia or maybe FirstGear, but it's still good gear and the pricing is very reasonable. I still wear my TourMaster stuff more often than anything else.
So that's my $0.02.... :-)
