The Thermarest MondoKing 3D is a luxurious mattress with sidewalls, designed to give to most comfortable nights sleep when camping. The sidewalls give the major advantage of increasing the usable sleep surface by 20% as you can now lie all the way to the edge of the mattress without it collapsing and you rolling off onto the floor. It also makes using it with another 3D mattress to create a double bed much easier as they can now be put directly side by side. At 10cm thick, with an R-Value of 7.0 it provides excellent insulation from the ground and will cope with the coldest temperatures. The foam core means that it is a self inflating mat so there's no need for pumps and batteries, just unroll it, open both the TwinLock valve and leave it to do its thing, it will then require a few breaths to get it to the desired firmness. The new TwinLock valve system uses two one-way valves which allows for easier inflation and more rapid deflation. The outer fabric is a supple stretch knit fabric which breathes well to prevent clamminess and give next to skin softness. It also comes with a stuff sac with a carry handle.
