Therm-a-Rest MondoKing 3D Sleeping Pad - Unisex


See available self-inflating sleeping pads


Comfort on a massive scale: this is the thickest Therm-a-Rest® self-inflating mattress ever. Vertical sidewalls max out the sleeping surface to give you a huge, soft space to sink into at your campsite. It’s warm – like, really warm – and offers more stability than a standard air mattress that’s twice as thick. No pump is required to puff it up, which your campground neighbours will appreciate if you roll in after dark.

  • Made of long-lasting 75-denier polyester
  • 10cm thickness smooths out rough campsite surfaces
  • Generous width and length gives you room to move around
  • Toasty R-value of 11.4 means lots of warmth
  • Compressible foam core expands when you unpack it
