Description

For basecamp comfort when packed size is less important than sleeping room, MondoKing 3D uses a self-inflating foam core and vertical sidewalls. Its ASTM R-value is 7.0. Compare the size you choose with the usable floor of a tent or sleeping platform, leaving space for wheel wells and other obstructions if camping in a vehicle.

Questions

What does MondoKing 3D R 7.0 tell me?
It describes the pad’s tested thermal resistance, not a guaranteed overnight air temperature. Pair it with an appropriate bag and shelter for the full sleeping system.
Will self-inflating foam reach my preferred firmness without adjustment?
Opening the valves allows the foam to expand and draw in air. Top up or release air to adjust support, following the TwinLock valve instructions. Self-inflating does not mean automatic pressure regulation.
Can I assume MondoKing fits any vehicle sleeping platform?
No. Compare the length and width of the size you choose against the usable platform, including wheel wells, folded seats and tailgate clearance. The product is a sleeping pad, not a vehicle-specific fitted mattress.
