Mega in size, comfort and warmth: this is as comfortable as it can get away from your bed at home (warning: might be better than your home sleep experience!). In a campground, van or as a guest bed, MegaMat is the most luxurious mat available. Vertical sidewalls provide comfort from edge to edge. 10 centimeters of plush, open cell foam and a stretch tricot top surface cradle the body in comfort. Smart pack sack: Height-adjustable roll top bag with carry strap, which can also be used as a shoulder bag.
