Self-Inflating Pad with Built-In Pump

The Elegear CumbreX pad integrates a rechargeable electric pump that inflates the mattress in about one minute and deflates it in two. A full charge takes roughly three hours and provides up to twenty minutes of pump runtime, so campers can set up or pack away without manual effort.

R-Value 9.5 for Four-Season Warmth

With an R-value of 9.5 the pad delivers high thermal resistance suitable for spring, summer, autumn and winter conditions. The 26D memory foam core distributes weight evenly across the 78 by 51 inch surface, supporting up to 800 lbs without bottoming out on uneven ground.

Single-Person Full-Size Footprint

The mattress measures 78 inches long by 51 inches wide and rises 3.15 inches when inflated, offering one sleeper a full-size footprint. Buyers needing a double-width pad or a lighter backpacking option will find this model too wide and heavy for those uses.
