Built with StrataCore construction, the Therm-a-Rest MondoKing 3D Sleeping Pad lets you camp like royalty with luxury support and 3D shape.

The MondoKing 3D provides the highest level of comfort and support in the Therm-a-Rest sleeping pad range. With an incredible 4.25 inches (11cm) of premium foam, this ultra-cosy sleeping pad features a plush next-to-skin feel and a 7.0 R-value that will keep you warm and comfy in any condition or season. The StrataCore construction provides lofty three-dimensional shape, and compresses easily to save room in your trunk or closet. The easy-to-use TwinLock valve means the sleeping pad can inflate three times faster and deflate five times faster. Like all Therm-a-Rest pads, the MondoKing 3D is made in market to ensure quality and minimize environmental impact.

The pad includes a go-anywhere stuff sack with a built-in pump sack.
