If you are talking about goretex bibs, then also consider MEC.
If you are talking about softshell bibs, then yes the ArcTeryx gamma salopette is pretty much the only thing left. My religious fondness for softshell bibs been made fun of in previous threads along these lines, but I still don't know why softshell bibs have fallen off the market so much. Moving more than 10mins in goretex pants is a friggin sauna for me.
