I just bought this mattress using my normal obsessive scrutiny of available products. I really wanted the Thermarest Neo but at twice the price, I baulked and opted for the Prolite Plus which is new. It is very light and the thermal properties are amazing so I was well pleased with my decision. It is, however, very narrow and inconvenient for a base camp. I bought it mainly for packing in the kayak and I can easily say it will be perfect. My two nights on it so far have been comfortable and warm. I can understand why old hands love Thermarest mats. I will too.
