Cots breathe way better than inflatable mattresses.
Cots have just about been the best idea we have had after a couple of bonnaroos. Positive aspects of a cot...
They breathe. You won't wake up to as big of a pool of sweat compared to a blow up mattress.
still small in packing size. check out this cot. it folds up into something about the size of a folding chair.
You get more storage space in your tent. You can now pack stuff under your mattress.
it is cleaner. if your tent gets dirty, at least you are up and off the ground area.
