Product Description

The MondoKing 3D provides Therm-a-Rest's 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.
