I've searched all over and found varying bits of advice on what's the best type of suit is to commute in.. One piece or two.. I'm commuting on a 800GS through the typical Sonoma Coast fog and 30ish temps for roughly 30 minutes. I'm currently using 10 year old "stay-puff marshmallow" suit, one piece - no armor. The suit is literally disintegrating more at every use.. I want to upgrade, but not sure if I want to continue with the one piece suit, or just buy some nice pants to go with my new jacket.. I really like the Aerostitch one piece, but they don't look at all insulated - so that won't work.. Leaning now toward a First Gear Thermo - but I would really want a bit of armor. Any opinions as to what works better for water proof, cold resistant and longevity??
