First and foremost, it is a sleeping pad...the 10% is just a perk of the pad. A goose down sleeping bag will do little to offer comfort over a rough sleeping area. Also, while I have not invested in a top of the line sleeping bag, the purpose of the pad is to get you off the ground, so that it does not suck the warmth out of you. Any bag I have been in on bare cold ground does little to keep you comfortable. Hiking is not about comfort...but resting is!!!
