Comfort Riders, LLC
The semi-solid thermal energy storage material (PCM) is designed to absorb heat generated by the wearer. It remains thermally stable at 65°F. With PCM technology, you'll stay cool, dry and comfortable at a temperature that feels natural to your skin. So comfortable in fact, the Comfort Rider Cool Vest can be worn directly against your skin without the fear of frost-bite.
Unlike evaporative technology cooling vests, the Comfort Rider Cool Vest is completely dry.... you do not soak it in water. This allows you to ride without the "slimy", wet feeling associated with evaporation vests. Since the phase change technology incorporated in the Comfort Rider Cool Vest is a conductive heat transfer technology, we can guarantee that, not only will you "feel" the difference, your body's core temperature will remain stable longer than with any other "portable" technology.
