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.
 WARNING: Can expose you to toluene, which is known to the State of California to cause birth defects or other reproductive harm.

  • Stable Comfort: 4 inches (10 cm) of stabilized loft provides the comfort of home anywhere.

  • Giant Sleep Surface: Vertical sidewalls maximize useable sleep surface.
  • Incredibly Warm: Foam core delivers all-season warmth to assure a great night's rest anytime.
  • Easy to Pack: StrataCore construction allows the pad to easily compress and pack away.
  • Mateable: Mates perfectly with other 3D mattresses.
  • TwinLock™ Valve: Utilizing two one-way valves, one for inflation and one for deflation, the TwinLock valve system makes setting up and breaking camp a breeze.
