Whether you are using it as a standalone pad for summer fast-packing or as a protective, insulating layer beneath an air pad for winter expeditions, the Z Lite SOL delivers consistent performance in any environment.

This "SOL" version features a specialized ThermaCapture™ surface—a reflective coating that captures radiant heat and reflects it back to your body, increasing overall warmth by nearly 15%.
