My hands tend to run cold even in cooler weather, so figure that in, but I am glad I found these gloves. I have tried other gloves, recently the Castelli Cw.3.1 and Gore Tool SO, and none kept my fingers warm. They were cold from the start and took a long time to finally start to warm up. These Craft gloves are great and my fingers were warm from the start. Never got too hot and seemed to pull the sweat away well. The lobster design takes a few minutes to get used to but gives you plenty of dexterity on the bike. Nice material on the back of the thumb for the occasional nose wipe and the velcro cuff is of decent length and nice closure. My hands measured 8.5" around without the thumb and I went with the Mediums. Fit great. A large would be a little too big and extra material I believe. I was riding in windy conditions around 35 degrees and all digits were toasty. Highly recommended.
