Fall and spring are a fine line for riding weather, my friend. It's almost impossible to know how to dress for a day that starts cool, gets hot, then gets cold again. Nashbar Thermal Knee Warmers take some of the guess work out of it though. They help protect your knees from the cold and damp without covering your entire leg, so you don't turn into a huge, sweaty mess after the third pedal stroke.
Warm fleece backing wicks away moisture and helps retain heat in cold weather
Stretchy lycra construction moves with your body to eliminate chaffing or rubbing
Silicon grippers on top help the warmers stay in place while you're riding hard
