MondoKing™ 3D Sleeping Pad is built with StrataCore construction, camp like royalty with luxury support and 3D shape.

The MondoKing 3D provides our highest level of comfort and support. Boasting 4.25 inches (11cm) of premium foam, the ultra-cozy pad combines a plush next-to-skin feel with an 7.0 R-value to keep you warm and comfy in any condition or season. StrataCore construction provides lofty three-dimensional shape, and compresses easily to save room in your trunk or closet.

The extra-comfy self-inflating pad features the easy-to-use TwinLock valve, allowing the pad to 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.
