Thermarest's lightest most compact closed-cell mattress is now warmer than ever: a new aluminized surface reflects heat increasing overall warmth by nearly 20%.

Therm-a-Rest says:

Always a favorite of the ultralight elite, the Z Lite SOL expands upon the utralight performance of the Original Z Lite by adding our reflective ThermaCapture™ coating to capture radiant heat and increase overall warmth by nearly 15%. Factoring in the system of heat trapping dimples, the Z Lite SOL has an R-Value of 2.0, making it perfect for use on its own in warmer weather or layering under another pad for extra warmth in the cold. The proprietary foams are softer on top for extra comfort and denser on the bottom for extra durability, making the Z Lite SOL an idealclosed-cell foam pad for those in need of an ultralight, highly compact and super-reliable sleep system.

The Z-Lite from Thermarest takes the closed cell foam mat to the next stage moulded with an egg box surface it offers more comfort and insulation that conventional closed cell foam mats. The SOL version is warmer for minimal weight penalty.

*ASTM R-Value:

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.

You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.

In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
