Cimarron is a great tent (as most of SO's lineup), but some folks have the wrong idea about a lightweight hot tent- the stoves are very light, but also very small- they are really meant to take the chill off in the evening/morning, help dry clothing, cook a meal, etc but it's unrealistic to think that it's going to keep you warm all night long. Simply too small of a wood box, you'd have to be feeding the stove all night long- which means not a lot of rest.
I love mine, but always plan on the proper rated sleep system for the expected weather.
