The mat acts curled quite large for 190x120, will give it a try with wrinkles, possibly taking the backpack not as much space as the great role.
Spread it is very difficult alone, because they are not of themselves completely unroll and you like four hands would have to lay it on the floor.
About the insulation I will report.
The tabs that will prevent the mat on the roll, are not really suitable for this purpose. One side is me already torn from the attachment, but does not bother me, because I always do not wear it on the tab, but the backpack. In general, the seams appear very banal high. Eyelets at the corners would still like to see me, but will probably have to upgrade themselves.
