Not That Warm
I have used these gloves twice in 33-37 degree weather and the my hands were cold in the first 5 minutes. I had to go back and get my Defeets and wear them under the liners to keep my hands warms. Sorry Giro but for $70 I would expect more. The liners do absolutely nothing and are very thin. I even sized up as tight gloves mean cold hands.
For sizing, my hand measure 8 7/8 inches around the knuckle and they fit well.
