Bike Fridays are made in Eugene, Oregon. Lunas were made in New Mexico and Colorado but are no longer made at all.
Arkel panniers and stuff is made in Quebec. Cocotte is a Canadian maker of courier bags (Montreal). There are several Canadian bike builders, but I don't know the names. Other bag makers in the US are Rickshaw and quite a few other small shops in SF and other places. I'm not sure that Timbuktu bags are still made in the US, but they might be.
Ortlieb is a German company, but I don't know where their items are actually made.
