The Prolites are good. My SO has the Prolite Plus Women's model which has a higher R value due to a bit more insulation in the lower and foot part of the mattress. She swears by the sleeping pad and has logged plenty of nights of comfortable sleep on it over the last couple of years.

I don't have a Prolite but instead, use a MEC Kelvin model non-insulated air pad. The Kelvin models are no longer made but I have had mine now for about 3 years with no problems and no leaks. Like the Prolites, the Kelvin rolls up very compact and is not much taller in height then a Nalgene bottle.
