"So comfortable you won't want to get up"
Got this for year-round car camping, and it's awesome. My winter backpacking setup is a Thermarest Prolite Plus on top of a Thermarest Z-Lite Sol, and this Mondoking is way more comfortable than those two stacked together. As a side-sleeper, it's a real blessing. Comes with nice stuff sack, too. It rolls up to a size which is about 150% the volume of the Z-Lite Sol. For cool weather use, note that the rated R-value for insulation is very high, but I have not yet tested it in winter to see if the rating is accurate for real-world conditions. Having used Thermarest's other mattresses, I am confident that their rating was carefully considered. Lastly, it's always nice to buy stuff made in the USA, and this is made in Seattle. If this were stolen from my tent, I would replace it in an instant.
