Key features & specs

How it compares

Unlike inflatable sleeping pads that can leak or pop, the Therm-a-Rest Z Lite Sol is virtually indestructible. While it offers less cushioning than a 3-inch air mattress, it provides immediate utility as a sit pad or a changing station during trail breaks. Compared to standard green foam pads, the Sol version features a silver ThermaCapture coating that reflects radiant heat back to your body, increasing warmth by nearly 20% without adding weight.

How to use it

1. Undo the elastic closure straps and unfold the pad onto your tent floor or a flat patch of ground.
2. Place the silver (reflective) side facing up toward your body to maximize heat retention.
3. If using as a sit pad, leave the pad partially folded to create a thicker, cushioned bench.
4. To store, simply refold the accordion sections; the nesting dimples ensure it stays compact.
5. Clean by simply hosing it down or wiping with a damp cloth; the closed-cell foam will not absorb water.

Frequently asked questions

Is the Therm-a-Rest Z Lite Sol worth it?

Yes, for under $60, this pad is one of the best values in the industry due to its lifetime durability. It is a piece of gear that literally cannot fail you in the field.

Does it work for side sleepers?

While side sleepers can use it, some may find the 0.75-inch thickness too firm for their hips. It is best suited for back sleepers or those who prefer a very firm sleeping surface.

How does it compare to inflatable pads?

The Z Lite Sol is much more durable and faster to set up, though it offers less cushioning and a lower R-value. It is often used as a backup or a foundation for an inflatable pad in harsh conditions.

Which side of the Z Lite Sol goes up?

The silver, reflective side should face up toward your sleeping bag to reflect your body heat back to you. The colored side faces the ground to provide the primary barrier against the earth.
