Bontrager's Rhythm Comp Gloves are serious gloves for serious riders. Heavy duty Clarino palms with light padding keep your precious grip when you're on the bike. Knuckle Dragger pads, Aeroprene at your index fingers and wrists and abrasion-resistant nylon protects your hands when you're off the bike, too. Plus, the stretch mesh and air vents keep your hands comfortable. If you do heat up, the fleece thumbs make quick work of that.
