Insulated leather gloves hold off the bite of winter, but they'll suffocate your hands in hot weather. Like the jacket we just talked about, look for gloves with mesh or perforations on the knuckles and leather on the palms. The mesh redirects airflow to cool your hands, while the leather lessens the vibrations pulsing through your hands and protects them in the event of a crash.
Many pairs incorporate carbon fiber -- a material that is as strong as steel while carrying a fraction of its weight -- to protect the fingers and knuckles. Always wear gloves designed for motorcyclists: Don't substitute golfing or batting gloves, and never wear gloves with open fingers.
