Thermarest: ProLite 4 - Sleeping Pad (Small)

Great for backpacking and mountaineering, the Thermarest Prolite 4 Sleeping Pad, Small weighs barely more than a pound, which isn't all that much when you consider the importance of a good night's sleep on strenuous backcountry trips. It provides enough insulation for use on snow but because it's only 47 in. (119 cm) long many experienced alpinists and weight-conscious backcountry skiers pair it with a full length and lightweight Thermarest Z-Lite™ or RidgeRest® for deluxe warmth and cushioning from head to toe. And for trips that don't involve snow camping, they prefer the Prolite 4 Sleeping Pad, Small alone for the extra half inch (1.3 cm) of cushioning than offered on the Thermarest Prolite 3 Sleeping Pads.
