MicroSensor-Thermal material wicks perspiration and insulates your lower extremities on cold days.

If you don't want all the fabric coverage of a traditional leg warmer Pearl Izumi's Microsensor-Thermal Knee Warmer gives you the right amount of warmth along your upper leg and knee area. Unlike some bike clothing manufacturers who treat the construction as a matter of stocking design Pearl Izumi opted for a three-panel anatomically-shaped process that feels right around your legs--especially after grinding up a series of switchbacks or steep hills. The Pearl Izumi Microsensor-Thermal Knee Warmer uses chafe-free flatlock stitching with external silicone hits along the hem that help create a secure seal where the warmers and your shorts meet.
