Thermarest Neo Air All Season
Cant be beat by anyone, IMO
I have used that product -30 multiple nights 7-10 k out
In the woods, multiple trips, All seasons, they are light, warm and safe
In the really cold season I use a 4 season Bivy bag , foil blanket on the bottom than mattress
It keeps you insulated and warm, and also prevents you from falling off of said air mattress,
A proper bivy will also keep you face vented from your body, keeping moisture down.
I have slept on the Ice of frozen lakes with that setup and woke up warm and happy
Therma rest is the origonal mattress maker and has been doing it right for a long time
They do come with repair kits, and there is a slew of accesories to inflate, or turn into
A chair etc etc,
