Therm-a-Rest MondoKing 3D (Closeout) Self-Inflating Sleeping Pad

If you are looking for maximum comfort and a sprawling sleeping base for your next camping trip, look no further. The Therm-a-Rest MondoKing 3D self-inflating sleeping pad is 4" thick, has a comfortable "next to skin" feel, and delivers an R-value (11.4) worthy of year-round use.

Designed for campers who aren't necessarily looking for a streamlined backpacking pad and aren't concerned with packed weight, the mattress offers extra-thick foam padding for warmth and comfort. A full 4" layer of foam serves as a comfortable sleeping base and the ultra-responsive foam core contours to your body to provide great comfort and support. Soft stretch-knit fabric offers cozy next-to-skin comfort. The pad has a sprawling sleeping surface and the vertical sidewalls maximize loft.

The self-inflating design allows you to simply unroll the pad and open the integrated air valve. The open-cell foam core responds by soaking up air, similar to a sponge absorbing liquid. Once the mattress has reached initial inflation, you can achieve the full 4" thickness by adding a few puffs of air through the dual valves or you can fine-tune the density by pressing down lightly on the pad to release air.

The Therm-a-Rest MondoKing 3D is available in Large (25" x 77") and XXLarge (30" x 80") size options.
