Have you ever wondered how the insulation in a NeoAir works? It’s surprisingly simple.
All Therm-a-Rest NeoAir air mattresses have the same honeycombed air baffles, shown in the photo above. These run from one side of the air mattress to the other, unlike many other manufacturer’s sleeping pads where the baffles run lengthwise.
Therm-a-Rest adjusts the insulation power or R-value of each pad in its NeoAir product line by adding a metallic reflective coating to the inside of the baffles: the more baffle surfaces that are covered, the higher the R-value of the pad. See Sleeping Pad R-Values.
|Model||Size||R-Value||Weight (oz)||Width (in)||Length (in)||Thickness (in)|
|NeoAir All Season||Medium||4.9||18||20||66||2.5|
|NeoAir All Season||Regular||4.9||19||20||72||2.5|
|NeoAir All Season||Large||4.9||25||25||77||2.5|
|Womens NeoAir Xlite||Regular||3.9||11||20||66||2.5|
Think about it this way: when you lie on a NeoAir sleeping pad, your body heat warms the air inside the mattress baffles. The metallic coating helps reflect that heat back at your back and helps regulate the rate in which the trapped heat is radiated out of the pad and back into the air surrounding you.
Therm-a-rest also adjusts the rate of radiation loss by using different exterior fabrics on their sleeping pads, letting them dial-in different R-Values for different customer preferences and uses.
Pretty clever, huh?
