Any outdoors person will tell you a comfortable night's sleep is integral to enjoying the outdoors. The MondoKing 3D from Thermarest will ensure you are recharged for the next day of adventure.


Drawing on years of experience, reseach and development, Therm-a-Rest have produced another quality bedding component to include in your outdoor sleeping experience. Boasting an R-Value of 7.0, this all season matress is designed durable for longevity and comfort that you can't leave home without. The TwinLock valve allows inflation three times faster but also deflate five times faster.

Designed for the camper that relies on their gear and with the bonus of added comfort, the MondoKing 3D is an easy choice. Also able to be connected to any other Therm-a-Rest 3D mat you can make it into a double with ease. The pad includes a go anywhere stuff sack with a built-in pump sack to add more firmness if desired.

  • StrataCoreTM Construction: Yielding an impressive warmth-to-weight ration. StrataCore uses a continuous layer of thermal foam nestled between alternating ridges of air and foam
  • Comfortable Fabric: Supple stretch knit fabric provides deluxe breathability and plush surface
  • Giant Sleep Surface: Vertical sidewalls maximise the usable 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
  • TwinLockTM Valve: Utilising two one-way valves, one for inflation and one for deflation, the TwinLock valve system makes setting up and breaking camp a breeze.
  • Pump stuff sack included
