This is my first winter biking outdoors in Ohio. I've been using Bar Mitts, riding in temps down to 30 degrees (20s with wind chill) and they work great. I'm curious to know what you guys use when temps get to around 45-50. I've found those temps to be too warm for the Bar Mitts, but I had trouble in the fall finding gloves that provided coverage but didn't make my hands too hot. Any suggestions? Are there gloves that are semi-warm but breathable? Thanks
