I wear these most of the time when it's below 60 degrees. Below 40 I wear heavier Pearl Izumi gloves. The temperature range and wind resistance is excellent.
I have tried these gloves in a variety of temperatures below 50F. They are well made but don't depend on them to be be comfortable in the mid-40F's and below without wearing additional glove liners underneath. Love the neon/black.
I'm pleased with the fit and performance of these gloves. They fit well and are comfortable when cycling.
