I've spent at least 8 nights on my XLite regular in above and below freezing temperatures and it has been great. Every morning I've rolled it back up and stuffed it back in my pack in its little stuff sack. It's been a piece of cake to inflate and deflate as well. Except for once I've always put down a protective sheet below it; either the floor of my bivvy or tent, my hammock, or simply a groundcloth. I usually roll around a lot at night to get comfortable but this one lets me sleep comfortably on my back and side. It fits great inside my bivy and my Clark hammock, even when paired with a 0ยบ bag.
I have noticed some loss of the silvering on the edges only of the inside reflective barrier but I haven't noticed any loss of warmth. Since I bought mine at REI I am not worried about it; if the silvering all disappears I'll simply exchange it for a new one.
