+ durable, sturdy, - gapes, not soft
I bought this for my large Neoair All Season (2.5 inches thick, 25 inches wide). Unfortunately it gaped severely - maybe it is for even thicker mattresses like the MondoKing? Or I should have got the 20-inch wide? Seemed obvious the fabric would bunch up and bother me while sleeping.
I also found the fabric hard, so durable, yes (two stars for that and the sturdy buckles), but if you are buying it for the other feature of leaving it on as a sheet for your mattress, I don't think it would be comfortable to sleep on (except the cushy suede-like pillow which is very nice). Not to mention the design with the bottom curled under to form a seat - basically the bottom would pick up leaves, dirt, even mud - and then you sleep on that? This one is a miss for me, unfortunately, back it goes.
