I have been out my new x-lite for two nights, mid-20's on Pike's Peak, and low 30's another night up in the mountains. Amazingly warm for the weight. Although I anticipated lot's of noise based on what it "seemed" it would be when squeezing it in hand, it was not noisy at all when laying on it. Surely the increased air pressure from laying on it removes the "crinkling" noise almost altogether! I was pleasantly surprised, surpassed my expectation for comfort, heat, and noise.
