Reasons NOT to buy:
User Reviews

- “Self-inflation” is not very effective.
Expert Reviews

Summary:
The Therm-a-Rest ProLite Plus Sleeping Pad is a revelation for campers who have never used a foam-based inflatable pad, as it offers more comfort and warmth than more simple air mattresses. Although the insulation sacrifices some packability and makes the pad heavier, most reviewers are happy to take on the extra weight for the increased comfort. Although there are mixed reviews about the comfort of this pad for side-sleepers, it is certainly more quiet, comfortable, and durable than ultra-light camping pad models.
