Therm-a-Rest MondoKing 3D L 2XL - 80 x 30 Inches
If you want the best possible sleeping comfort when camping, you can't go past the MondoKing 3D sleeping pad from Therm-A-Rest. In its latest edition, it is more comfortable than ever before, even though it has shed a lot of unnecessary weight compared to its predecessor. The StrataCore construction gives the mat a ribbed shape with alternating air and foam ribs, which are underlaid with thermal foam throughout. This saves the mat a whole 500 g without compromising on sleeping comfort. On the contrary, the new MondoKing is now 11 cm high, still has the soft stretch knitted fabric on the outside and, thanks to its 3D shape, retains its height evenly right up to its edges. Another change concerns the valve. The new MondoKing 3D now has two independent valves - one for quick inflation and one for quick deflation. The TwinLock valve works in harmony with the pump bag supplied so that you can get the mat to the desired firmness quicker and without the hassle of re-inflating. The deflation valve and the ribbed shape also make it easier for you to roll the mat up again and store it in its pack sack.
