i've been looking for a uq in man made insulation- mostly be casue i dread getting down wet. and having to suffer. i don't think i'll be camping in winter, but do want full comfort for the 3's.mostly motorcycle stealth camping and in a year or two getting back into hikeing. anyway i have stumbled onto the mm and ttt sites and am trying to evalueuate the shamu ix. they don't cover much in the way of hard numbers. i'd like to know the width and packed size. another question i have, and a lot harder to answer is- what low temps. can i reasonably expect from this uq?
