The Pearl Izumi Gel-Vent gloves keep you cool and comfortable on hot days. The patented Direct Vent palm design includes ventilated gel padding, plus mesh fabric on the back of the hand to help keep your hands dry.
If you've cycled for a while (years), most everyone has tried various brands of gloves. But for years Pearl Izumi have been the leaders. The Men's PRO Gel Vent are about the best I've found. Very comfortable, lightweight and easy to remove (with sweaty hands).
