Thermarest MondoKing 3D XXL Camping Mattress

Camping equipment Rental Description

The MondKing 3D XXL is thick, warm, and comfortable. Whether you’re car camping, setting up a basecamp, or need a guest bed that isn’t an air mattress, this one does the job.
With 4.25 inches of foam, you won’t feel the ground beneath you, and at 80 x 30 inches, there’s plenty of space to stretch out. The R-value of 8.0 means it holds warmth well, even in cold conditions or on frozen ground. The TwinLock valves make inflation simple—just open them up and let it fill on its own. A few extra breaths can adjust the firmness, and packing it up is easy with the one-way deflation system.
The top fabric is soft and comfortable, while the bottom is tough enough for regular use. It comes with a stuff sack for storage and packs down to 31 x 10 inches. At 5 lbs. 8 oz., it’s not meant for backpacking but is perfect for car camping and van life.
