Thermarest Neoair Uberlite Review

Therm-a-Rest NeoAir XLite Sleeping Pad w/ WingLock Valve Review

OutdoorGearLab

The Therm-a-Rest MondoKing 3D, like other self-inflating camping mats in this review, is comprised of four inches of luxurious foam comfort. This model matches the warmth and comfort of the plushest mattresses in the test, facilitating some of the best sleep we've ever experienced outdoors. Its updated dual-valve system is what nudged it into the top spot. It is incredibly easy to inflate by attaching the stuff sack to the inflation valve and using the sack as a pump. The deflation valve is huge, meaning that air dumps out of it faster, and we were able to make quick work of rolling up the mattress and packing it away.  
If there is a downside to the MondoKing, it is simply the enormous packed size. It is not the biggest on our test, but it is close. If you camp with a significant other, you will need two. Trust us. That takes up a lot of real estate in the back of the car and the gear closet. We tested the XXL version for extra-deluxe sprawling pleasure, though it is available in a smaller size, meaning you might be able to fit two in your tent. The MondoKing is lighter than other mattresses of this type, but you aren't going to take it into the backcountry unless you have a packhorse. However, for car camping adventures, this is our favorite.
