The GripGrab Classic Knee Warmers are both insulating and breathable making them ideal for keeping your knees warm while cycling on cold days. Temperature is regulated thanks to a breathable brushed fleece fabric. A silicon elastic grip at the top of the knee warmer and diagonal stitch on the rear panel behind the knee ensures maximum comfort. The silicon grip hugs your leg creating an anatomical fit. By placing the seam diagonally down the back of the leg there is no rubbing caused by the seam increasing the comfort. Reflective logos add to your visibility and safety.
