It's a sleeping pad for when you're "roughing it" when camping. . Anyway you shape it, sleeping on the cold, hard, rocky ground is no fun. This pad softens the blow when you are sleeping on the ground so you sleep better in nature and can enjoy the next day. It can help you learn to love camping.
The Therm-a-Rest ProLite Sleeping Pad ($84.95) rolls up tightly and it's really lightweight, so if you're hiking to your campsite, you'll hardly feel it in your pack.
