>>1070261i've got a multimat ice mat 100 XXL that i've used for fifty-something winter camps.
pros: very thick = very comfy. i'm a side sleeper, but i can leave it underinflated and squashy without my hip and shoulder pushing through to the frozen ground. thinner mats i've owned would need to be inflated as tight as a drumskin to remain insulating, which is not comfy at all.
i can roll over in my sleep and still be on it (it totally fills a 2-man tent)
the 'self inflation' actually fills it most of the way.
carry bag is microfibre lined and big enough to be a body pillow.
cons: the packed size is very large. much larger than exped mats with comparable R-values.
squashing and rolling all the air back out to pack up is a ten minute job and can't be done quietly.
the extraordinarily aggressive velcro down one side has yanked loops out of my wool socks and gloves and torn holes in wicking polyester shirts.
