Best praise vs top criticism for Therm-a-Rest Z Lite Sol

Best Praise
+33 pts
The sleeping pad you seek is a used Therm-a-Rest Z Lite. It's good to just above freezing temperatures, findable for $20, 10oz before you cut it to size. It's not fun and it's big but warmth per weight and weight per dollar are unbeatable.

The ridgerest is really bulky, probably better to do the Z lite purely for that reason
