I've been commuting 20 miles each way here in NY and although I have Klim gear I've been getting chilled on my ride home below 40deg. I have heated gear but find it heats unevenly. I don't want to layer too much because when I'm at work, I'll roast. So, while looking for a 1 piece to go over my street clothes I see that unless I spend over $1000 for an Aerostich, there aren't too many manufacturers making one piece gear with built in protection. What are riders doing to get the protection and stay warm while commuting on their bike?
