Therm-a-Rest Z Lite Sol Sleeping Pad

The Z Lite SOL features a specialized ThermaCapture™ reflective coating on the surface. This aluminized layer reflects radiant heat back to your body, increasing the pad's overall warmth by approximately 15% compared to the original version.

With an R-Value of 2.0, the Z Lite SOL is best suited for warmer weather when used on its own. However, many backpackers use it as a base layer underneath an inflatable pad during colder trips to add extra insulation and protect the inflatable pad from punctures.

Yes, the pad is constructed with dual-density foam. The bottom layer is denser and tougher to withstand rough ground, while the softer top layer provides necessary cushioning for comfort.

The Z-fold design allows the pad to accordion-fold into a compact rectangle rather than rolling up. This makes it very easy to strap to the outside of a backpack or slide into a pack, though it will remain a fixed size rather than compressing further.

While the reflective coating may show signs of wear or minor flaking after extensive use and abrasion, this is normal for closed-cell foam pads. It does not significantly impact the pad's structural integrity or its ability to provide insulation.
