The proprietary foam is designed for both comfort and durability, with a softer top layer for cushioning and a denser bottom layer for protection against rough terrain. The ThermaCapture coating helps reflect body heat back to you, providing additional warmth on chilly nights.

Comfort & Insulation Performance

For a lightweight closed-cell foam pad under an inch thick, the Thermarest Z Lite SOL delivers surprising comfort and impressive ground insulation, making it a reliable choice for minimalist backpackers. The egg carton-style dimples help distribute your weight and provide cushioning.

While not as plush as an inflatable pad, I found it comfortable enough for side and back sleeping. This will vary person to person though.

The 2.0 R-value offers decent insulation for 3-season camping. In temperatures down to about 40°F, I stayed warm with just the pad and my sleeping bag. The reflective ThermaCapture coating noticeably retains body heat better than standard foam pads, making a difference on chilly nights.

Tip for Side Sleepers: Pair the Z Lite SOL with a lightweight inflatable pad for extra comfort and warmth, especially for colder nights or frozen ground.

Durability and Reliability: Bombproof and Worry-Free

One of the biggest advantages of closed-cell foam pads is their bombproof durability. There’s no risk of punctures or leaks like with inflatable pads. This makes it a stress-free choice for thru-hikers and off-trail adventurers.

I’ve dragged the Thermarest Z Lite SOL over rocks and roots with no damage. The dense bottom layer holds up against wear and resists compression over time, which is a common issue with cheaper foam pads.

You shouldn’t have to worry about your sleeping pad ruining your trip. There’s no setup or maintenance needed – just unfold and sleep!

Packability and Versatility: More Than Just a Sleeping Pad

At 14 ounces for the regular size, the Z Lite SOL is one of the lightest closed-cell foam pads on the market. The accordion-style folding allows it to compress down to about 20″ x 5″ x 5.5″.

While bulkier than some inflatable pads, I found it easy to strap to the outside of my pack.

The folded pad also serves many purposes around camp. I often use a section as a seat pad or to kneel on while cooking.

The full pad makes a great yoga mat for morning stretches too!

Backpacking Hack: Some minimalist backpackers even cut the pad in half to use part under their torso and the rest as a sit pad or gear protector.

Best Uses for the Thermarest Z Lite SOL

The Thermarest Z Lite SOL is a multi-purpose closed-cell foam pad that is better in some scenarios than others:

Ultralight Backpacking: Perfect for minimalist backpackers looking to shed every possible ounce from their pack.

Budget-Conscious Campers: An affordable option that doesn’t compromise on reliability and functionality.

Simplicity & Reliability: No risk of punctures or maintenance headaches – just unfold and sleep.

Winter Camping (as a Layer): Use it under an inflatable pad for extra insulation during cold-weather trips.

Thru-Hiking: Highly durable and ideal for long-distance hikes where gear failure is not an option.

Car Camping: If comfort is your top priority, there are thicker, plusher pads better suited for car camping.

Standalone Cold Weather Use: The R-value of 2.0 isn’t sufficient for sub-freezing temperatures on its own. Pair it with another pad for better insulation.

Side Sleepers: Those who sleep on their sides may find the cushioning too thin, especially compared to inflatable pads.
