Therm-A-Rest's ProLite is the perfect three-season mattress providing comfort with minimal weight and max compactness. It's 20 percent lighter than the previous prolite model thanks to a die cut foam which eiminates excess weight. However, you still get the reliable performance and comfort you need.  Bottom grips and textured top surface hold the mattress in place while you sleep.
