The small tendons, ligaments, and muscles around your knees play an integral role in your ride quality, so don't leave them cold and exposed when you're riding in unpredictable shoulder season weather. A light breeze in your driveway turns brisk in a hurry when you drop into a long descent, so cover your 'caps with the Castelli Thermoflex Knee Warmers to help ward off stiffness after hours on the roads. These stretchy fleece warmers insulate but remain breathable when you break a sweat, making them ideal for the changing temps during spring and fall.
