Therm-A-Rest MondoKing Mattress

Item No.   10212369

The Therm-A-Rest MondoKing Mattress is a self-inflating air mattress for super comfortable nights at the campground. The MondoKing is four inches thick for plenty of cushion underneath in any season. The R-value of 11.4 allows warm down to -40°F to give you an idea of the incredible range. Since it is self-inflating, all you need to do is open the valve and go about setting up the rest of your camp. Once you return, add in a little lung power to adjust firmness via breaths of air. Lay out and relax, the width and length has plenty of room to move about. The included stuff sack makes packing up the station wagon when heading to and from the site.
