Therm-a-Rest Dream Time Sleeping Pad
While these are perfectly functional, it is $200 for a mattress that could be replaced by $20 of foam. They weigh 8lbs and roll up to about 36" long by 12" in diameter. Unless you are on horse or car, your aren't taking these far. that said, I enjoyed borrowing these and they helped me stay toasty warm and comfortable. Good but not worth it. Buy a small thermarest and a foam pad for the cold,luxury nights.
