Mark Wwrote a review of Therm-a-Rest ProLite 4 Sleeping Pad on February 13, 2007
As you age, this stuff gets more important. From nothing, to foam, ensolite, thermarest foam, UL thermarest 3/4 lentgh,...at 46 years old, I want the thickest pad with a reasonable weight, otherwise you don't sleep well and your trip sucks. I got a reg pro lite 4 and it works great. No complaints. My wife also uses and loves the womens version. If your 18, buck up and sleep on the ground, 35 plus...get this pad!
