User Review: Therm-a-Rest Original Z-Lite

The Therm-a-Rest Z-Lite is plenty light, but for comfort it is sorely lacking. I took it on a trip to the high Sierras in California and did a lot of sleeping on hard surfaces and the mattress just did not provide adequate comfort. After tossing and turning for hours, I found that the only position that was tolerable was flat on my back. I was ready to toss the mattress in the garbage when I got back home.
